gENERAL DESCRIPTION

System Sensor Model BEAM1224/BEAM1224S is a long range projected beam smoke detector designed to provide open area protection. It is to be used with UL-listed, separately supplied power (4-wire) control panels only. The detector consists of a transmitter/receiver unit and a reflector. Smoke entering the area between the transmitter/receiver and reflector causes a reduction in signal. When the obscuration reaches alarm thresholds (chosen at the transmitter/receiver unit), the detector generates an alarm signal. Complete blockage of the beam causes a trouble signal. Slow changes in obscuration due to a build up of dirt or dust on the lens of the detector are compensated for by

D400-73-00 1 I56-2294-006R

a microcontroller that continuously monitors the signal strength and periodically updates the alarm and trouble thresholds. When the self-compensation circuit reaches its limit, the detector generates a trouble signal, indicating the need for service.

Three LEDs on the detector indicate the current status: a red LED for alarm, a yellow LED for trouble, and a blinking green LED for standby operation. The alarm signal latches and can be reset by a momentary power interruption, by using the remote reset input to the detector if using the remote test/reset station model RTS451, or with the local reset button located on the detector. The local reset button is accessible by removing the outer paintable trim ring. The yellow LED will blink in specific patterns to provide a diagnostic aid when diagnosing the cause of a trouble signal. It will also blink the amount of drift compensation that has been used at the conclusion of the test. Trouble signals automatically reset upon removing the cause of trouble. Red and yellow LEDs can be remotely connected to the remote Alarm and Trouble outputs. These outputs mimic the functions of the detector’s red and yellow LEDs. In addition to these indicators, there is a dual digital display that reads 00 to 99. This display is used to indicate the signal strength of the beam in alignment mode and to indicate the sensitivity setting of the detector in percent obscuration when setting the sensitivity of the detector. No additional equipment is needed for alignment of the beam.

Each detector contains one Form A (normally open) contact for alarm signals and one Form B (normally closed) contact for trouble signals. The trouble contact will open if power is removed from the detector. Thus, an additional

EOL power supervision relay is not necessary. The trouble contacts from all the beam detectors on one initiating circuit must be connected after the last indicating device on the loop. This prevents a single beam detector in trouble from disabling other initiating devices on the same loop.

SPECIAL APPLICATIONS

Due to the inherent capabilities of projected type beam detectors they are often installed in locations where spot-type detection is impractical. Projected type beam smoke detectors are ideally suited for environmental conditions that might include high ceilings, dusty and dirty environments, or environments that experience temperature extremes. Often these conditions present special problems for the installation of spot-type detectors and even greater problems for their proper maintenance. Due to the inherent flexibility of mounting locations and large coverage area of projected type beam detectors often the conditions above can be addressed or minimized.

Some examples of applications for beam detectors might include freezers, aircraft hangars, cold storage warehouses, shipping warehouses, enclosed parking facilities, sporting arenas and stadiums, concert halls, barns, or stables.

Some of these environments might be considered too hostile for spot-type smoke detectors. If the environment is considered to be hostile then the colder alarm threshold settings should be used.

Before installing the transmitter/receiver unit or reflector in these types of applications special consideration should be given to ensure proper operation of the beam detector. The beam detector should not be installed in environments where heavy condensation or icing is likely. Condensation or icing of the reflector surface or the outer surface of the transmitter/receiver unit will obscure the light beam resulting in a false alarm. If elevated humidity levels and rapidly changing temperatures can be expected then condensation will likely form and the application should not be considered acceptable for the beam detector. The beam detector should not be installed in locations where the transmitter/receiver unit, the reflector, or the optical pathway between them may be exposed to outdoor conditions such as rain, snow, sleet, or fog.

These conditions will impair the proper operation of the detector and must be avoided.

APPROvED ACCESSORIES

The following accessories can be purchased separately for use with this beam detector.

BEAMLRK

The BEAMLRK allows System Sensor reflected beam detectors to be installed at separations between 230 and 328 feet (70 to 100 meters). At these distances, four 8˝×8˝ reflectors must be used to provide enough reflected infrared light.

This kit includes 3 additional reflectors with new test scale legends. The reflector included with the transmitter/receiver unit is the fourth reflector to be used. This kit is not compatible with the multi-mount kit (BEAMMMK).

BEAMMMK

The BEAMMMK allows System Sensor reflected beam detectors and reflectors to be mounted to either a vertical wall or the ceiling. The kit allows for additional alignment range in cases where the detector and reflector cannot be mounted within 10° of each other. The kit includes the hardware necessary to mount either a single transmitter/receiver unit or a single reflector.

(To mount the transmitter/receiver the surface mount kit, BEAMSMK, must also be used). If the transmitter/receiver and the reflector require additional alignment range two kits are required. The kit is not compatible with the longrange reflector kit (BEAMLRK).

BEAMSMK

The BEAMSMK allows System Sensor reflected beam detectors to be mounted when surface wiring is used. This kit must be used when mounting the transmitter/receiver unit with the multi-mount kit (BEAMMMK).

6500-MMK

The 6500-MMK provides a heavy-duty multi-mount bracket for installations prone to building movement or vibration. It offers similar tilt and swivel flexibility found on the BEAMMMK. (To mount the transmitter/receiver to the

6500-MMK, the surface mount kit, 6500-SMK, must be used).

6500-SMK

The 6500-SMK allows the transmitter/receiver to be mounted to the 6500-

MMK heavy duty multi-mount kit.

BEAMHK

The BEAMHK allows the transmitter/receiver unit to operate in environments prone to the formation of condensation. Condensation forming on the beam detector unit may result in trouble or false alarm conditions. BEAMHK will lessen the likelihood of condensation by maintaining the unit at a temperature that is slightly higher than the surrounding air. Please refer to the BEAMHK installation manual for operation instructions.

BEAMHKR

The BEAMHKR allows the reflector to operate in environments prone to the formation of condensation. Condensation forming on the reflector may result in trouble or false alarm conditions. BEAMHKR will lessen the likelihood of condensation by maintaining the reflector at a temperature that is slightly higher than surrounding air. The kit requires a 24V power supply. When used with the long-range reflector kit (BEAMLKR), it is necessary to purchase and install four BEAMHKR kits. Please refer to the BEAMHKR installation manual for operation instructions.

RTS451/KEY or RTS151/KEY

The remote test accessory allows for the beam detector to be tested remotely.

The test accessory provides test and reset functions and green and red LED’s that mimic the LED’s on the detector.

DETECTOR PLACEMENT

This section of the manual discusses the placement of projected beam detectors. Though this information is based upon industry expertise, it is intended to be used only as a technical guide. Always comply with the requirements of applicable codes and standards such as, NFPA 72, National Fire Alarm Code, as well as directives of the Authority Having Jurisdiction (AHJ). For general information on the placement of detectors, read System Sensor’s Projected

Beam Detector Application Guide.

Projected beam detectors are usually located with their beams parallel to the ceiling. However, they can be mounted vertically or at any angle to protect the area involved. Since beam detectors sense the smoke buildup over a distance, they are ideal for locations with high ceilings. They can also be mounted on a wall or ceiling below the level of a spot type detector, reducing the effects of air stratification. Some typical locations would include large areas with high ceilings such as atriums, warehouses, and factories.

NOTE: Projected beam smoke detectors should always be mounted to stable mounting surfaces. See the MOUNTING LOCATION section for details.

Some fire codes specify spacing on a given center-to-center distance between detectors under ideal conditions. This spacing is based on rooms with smooth ceilings and no physical obstructions between the contents being protected and the detectors. Moreover, they are also based on a maximum ceiling height, and on the assumption that the value and the combustible nature of the contents of the room being protected do not warrant greater protection or closer spacing.

In a room with a smooth ceiling, detectors should be spaced horizontally between 30 and 60 feet (9.1 to 18.3m). One-half that spacing between the beam and the sidewall may be used as a guide. See Figure 1. The beam detector can be mounted with the transmitter/receiver on one wall and the reflector on the opposite wall, or both suspended from the ceiling, or any wall/ceiling combination. In the case of the ceiling mount, the distance from the end walls should not exceed one-quarter of the selected spacing (7.5 ft. [2.3m] maximum if the spacing is 30 ft. [9.1m]). See Figure 2.

In the case of peaked or sloped ceilings, codes may specify spacing of detectors by using horizontal spacing from the peak of the roof or ceiling. Figures 3 and

4 show the spacing for both the shed type and peaked type sloped ceilings.

On smooth ceilings, beam smoke detectors should generally be mounted a minimum of 12 inches (0.3m) from the ceiling or beneath structural obstructions such as joists, ducts, etc. See Figure 1 In addition, beam smoke detectors should be mounted vertically at least 10 feet (3.0 m) from the floor to avoid common obstructions from normal building usage. In many cases, however, the location and sensitivity of the detectors shall be the result of an engineering evaluation that includes the following: ceiling heights above 30 feet (9.1 m) – refer to the “Single-Ended Reflected Beam Smoke Detector” application guide A05-0095 for more information regarding the effects of stratification, structural features, size and shape of the room and bays, occupancy and uses of the area, ceiling height, ceiling shape, surface and obstructions, ventilation, ambient environment, burning characteristics of the combustible materials present, and the configuration of the contents in the area to be protected. As a general rule, reflective objects such as ductwork or windows should be a minimum of 15 inches (38.1cm) from the path of the beam

MOUNTINg LOCATIONS

Beam detectors require a stable mounting surface for proper operation. A surface that moves, shifts, vibrates, or warps over time will cause false alarm or trouble conditions. Initial selection of a proper mounting surface will eliminate false alarms and nuisance trouble signals.

Mount the detector on a stable mounting surface, such as brick, concrete, a sturdy load-bearing wall, support column, structural beam, or other surface that is not expected to experience vibration or movement over time. DO

NOT MOUNT the beam detector on corrugated metal walls, sheet metal walls, external building sheathing, external siding, suspended ceilings, steel web trusses, rafters, nonstructural beam, joists, or other such surfaces.

16 FT. (5M) MINIMUM

328 FT. (100M) MAXIMUM

C0255-00

In cases where only one stable mounting surface as defined above can be used, the transmitter/receiver unit should be mounted to the stable surface and the reflector should be mounted to the less stable surface. The reflector has a much greater tolerance for the unstable mounting locations defined above.

D400-73-00 3 I56-2294-006R

MOUNTINg INSTRUCTIONS

The transmitter/receiver unit may be mounted over a recessed junction box.

The cavity behind the detector is then used for routing of the wiring from the junction box to the terminal blocks on the detector. The transmitter/receiver unit should be mounted to the wall such that unit covers the recessed junction box in the wall completely. If the junction box is not recessed then you may use the surface mount kit (BEAMSMK). See the BEAMSMK installation instructions for surface mounting instructions. The transmitter/receiver unit can be mounted to the wall using the supplied drilling template (see Appendix

II). The detector base has 4 primary mounting keyholes, one in each corner of the base. All four hole locations should be used to provide a secure mounting.

The outer housing of the beam detector is held to the base using four screws.

In order to mount the detector you must remove the outer housing first.

The reflector can be mounted to the wall using the supplied drilling template see (Appendix III). The reflector has 4 mounting holes, one in each corner.

All four hole locations should be used to provide a secure mounting. The reflector must be mounted such that it is within 10° in both the X and Y planes of the transmitter/receiver unit. See Figure 5a. The reflector must also be mounted such that the plane of the reflector is perpendicular to the optical line of sight to the transmitter/receiver unit. The maximum tolerance for nonperpendicular mounting locations is 10°. See Figure 5b. If the reflector cannot be mounted within 10° of the transmitter/receiver unit then the multi-mount kit (BEAMMMK) or the heavy-duty multi-mount kit (6500-MMK) may be used to provide greater angular adjustment of the transmitter/receiver unit. If the perpendicular plane of the reflector cannot be mounted within 10° of the optical line of sight then the multi-mount kit can be used for the reflector. See

BEAMMMK or 6500-MMK instructions.

To aid in locating the reflector in the alignment mirror at long distances a an orange, adhesive-backed sheet of paper is provided. Remove the protective backing from the orange paper. Temporarily affix the orange paper next to the reflector. The location of the paper is not critical. It may be placed anywhere near the reflector as long as it not covering the reflective surface of the reflector. This paper should be removed once the installation is completed.

MOUNTINg CONSIDERATIONS fOR SINgLE ENDED BEAM DETECTORS:

There must be a permanent clear line of vision between the detector and the reflector. Reflective objects must not be near the line of vision between the detector and reflector. Reflective objects too near to the line of sight can reflect the light beam from the transmitter to the receiver. If this occurs, the detector will not be able to distinguish these reflections from those of the reflector and the protected space will be compromised. Reflective objects such as ductwork or windows should be a minimum of 15 inches (38.1cm) from the path of the beam. In cases where reflective objects cannot be avoided, the complete reflector blockage test can be used to determine if the installation is acceptable.

See Testing and Maintenance Section of this manual.

Light sources of extreme intensity such as sunlight and halogen lamps, if directed at the receiver, can cause a dramatic signal change resulting in fault and alarm signals. To prevent this problem direct sunlight into the transmitter/ receiver unit should be avoided. There should be a minimum of 10° between the pathway of the light source and detector and the line of sight between detector and reflector.

Operation of the detector through panes of glass should be avoided. Since single ended beam detectors operate on a reflection principle, a pane of glass perpendicular to the line of sight between the detector and the reflector can reflect the light beam from the transmitter to the receiver. If this occurs, the detector will not be able to distinguish these reflections from those of the reflector and the protected space will be compromised.

Panes of glass will also absorb some of the light as it passes through it. This absorption of light will reduce the acceptable installed distance between the detector and the reflector.

In cases where operation through panes of glass cannot be avoided some specific installation practices can help to minimize the effects of the glass. These practices include: avoid penetration of multiple panes of glass, position the glass so that it is not perpendicular to the line of sight between the detector and the reflector, (A minimum of 10° off perpendicular should be considered), and make certain that the glass is smooth, clear and mounted securely. The complete reflector blockage test can be used to determine if the installation is acceptable. See Testing and Maintenance Section of this manual.

Where high ceilings (in excess of 30 feet or 9.1 meters) are present additional beam smoke detectors mounted at multiple heights may be required to detect smoke at lower levels. See the Detector Placement section in this installation manual.

wIRINg INSTALLATION gUIDELINES

Always install all wiring in compliance with the National Electrical Code, and/ or the applicable local codes, and any special requirements of the local authority having jurisdiction. Proper wire gauges and suitable means for strain relief should be used. The conductors used to connect beam smoke detectors to control panels and accessory devices should be color-coded to reduce the likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire.

Installation wire used for the beam detector shall be no smaller than 22 AWG

(1.0 mm2). For best system performance, all wiring should be twisted pair and installed in separate grounded conduit. Do NOT mix fire system wiring in the same conduit as any other electrical wiring. Shielded cable may be used to provide additional protection against electrical interference.

When installing the beam smoke detector in applications where the head unit will be mounted to either a wall or the ceiling using the multi-mount kits(BEAMMMK or 6500-MMK) flexible conduit will be used. The surface mount kits (BEAMSMK or 6500-SMK) and multi-mount kits (BEAMMMK or

6500-MMK) must be installed with the cable before wring the unit, according to the instructions supplied with the kit.

When the detector has been mounted over a recessed junction box, all wiring should be routed out of the box and behind the detector to the bottom of the detector where the terminal blocks are located. When installing the wiring in the junction box be sure to leave enough wire in the box to connect to the terminal blocks. (Approximately 9˝ [23cm) of wire outside of the junction box will be required for proper installation). All wiring to the detector is done via pluggable terminal blocks. In order to properly make electrical connections strip approximately

˝ (6mm) of insulation from the end of the wire, sliding the bare end of the wire under the clamping plate screw.

Figure 7 shows all the wiring connections to the transmitter/receiver unit.

Figure 6 shows the proper wiring diagram for either class A or class B operation. Figure 8 shows the connections that are necessary when using one of the optional remote test stations. Figure 9 shows the remote outputs for trouble and alarm.

INSTALLATION/ALIgNMENT

Reference Figures 10 through 14 for installation, alignment, and maintenance.

Please make sure to complete all steps in order to ensure a successful installation. Proper application, mounting, alignment, and set-up will minimize false alarms and nuisance trouble signals.

C0271-00

WARNING: Disable the zone or system before applying power to the beam detector to prevent unwanted alarms. When applying power to the beam detector before the alignment procedure has been completed the detector may enter alarm or trouble.

D400-73-00 5 I56-2294-006R

PRE-ALIgNMENT ChECkLIST

• Ensure that both the detector and reflector are mounted securely to stable surfaces.

• Ensure that all wiring is correct.

• Ensure that terminal blocks are fully seated into their receptacles on the detector.

• Complete any wiring dressing to minimize movement to the detector once the alignment procedure is completed.

• Ensure that the appropriate number of reflectors are used for the installed distance. Distances between 230 & 328 Feet (70 - 100m) require additional reflectors (4 total). The BEAMLRK accessory should be used in these cases.

• Ensure that the line of sight between the detector and reflector is clear and that reflective objects are not too near. See mounting Instructions for more details.

• Ensure that both the detector and reflector are mounted within their operational parameters for off axis angles. See Mounting Instructions for more details.

• Disable the zone or system to prevent unwanted alarms before applying power.

• Ensure power to the detector is “ON”.

You are now ready to begin the alignment procedure.

STEP 1. COARSE ALIgNMENT

Refer to Figures 11 and 12 for this step.

1. Ensure that both optics lock-down screws are loose (Figure 11).

2. Look through the alignment mirror and find the reflector (Figure 12). If it is difficult to spot, use the orange adhesive-backed paper installed with the reflector as a reference. Make sure there are no people or objects obstructing your view of the reflector. This is also a good time to confirm that there are no obstructions or reflective objects within 15” (38.1cm) of the beam’s path.

3. Once you’ve located the reflector in the mirror, adjust the horizontal and vertical alignment wheels (Figure 11) until the reflector is centered in the mirror. The objective is to align the reflector with the hole in the gunsight and the circle on the mirror. This step will take some practice.

Your eyes must shift focus between the reflector and alignment gunsight in order to successfully complete step 3.

STEP 2. fINE ADjUSTMENT

Refer to figures 10 through 12 for this step.

1. Ensure that neither you nor any other objects are in the line of sight between the detector and the reflector.

NOTE: This detector has a built-in amplifier that will occasionally adjust its gain, or detection sensitivity, throughout the alignment process. This will be indicated by a “--“on the digital display. Do not disturb the detector while the gain is auto-adjusting.

2. Depress the alignment switch once (Figure 10). Both the digital display and yellow LED should turn on (Figure 11). The display should read

“--“ indicating an electronic gain adjustment. After a few moments, the display should show a number. If the display reads “Lo”, confirm that you’ve completed the steps in the pre-alignment checklist and repeat the coarse alignment process. The display will continue to read “Lo” until the detector receives enough light from the reflector to function properly.

3. With the display indicating a numeric value, begin adjusting the horizontal adjustment wheel in the direction that increases the number on the display. When the number starts decreasing, continue rotating the knob

3-4 revolutions past the peak value to confirm that you’ve truly reached the peak. Once you have confirmed that the true peak was reached, rotate the knob back until you reach the peak value again. Repeat this process with the vertical adjustment knob.

NOTE: If a value of 90 is reached, the detector will display “--“, indicating that it is auto-adjusting its gain. Once a numeric value returns on the display, you can continue adjustment. The number displayed after the gain adjustment will be much lower than 90 in order to make it easier for you to find the peak value. The number only aids in alignment – it is not an indicator of signal strength.

4. Repeat step 3, switching back and forth between the horizontal and vertical adjustment knobs until you have achieved the peak value. Remember that the goal is not to reach a value near 90; rather, it is to reach a peak whereby the numbers decrease with further rotation of either the horizontal or vertical adjustment knob.

5. Once satisfied with the alignment, depress the alignment button. The digital display will turn “OFF” and the yellow LED will remain “ON”.

This step must be performed or else the alignment procedure is void and the information will be lost.

STEP 3. SENSITIvITy SELECTION

Set the sensitivity of the detector using the sensitivity switch (Figure 10) and digital display. Use the chart below to determine which setting is acceptable

(per UL 268) for your installed distance. Before attempting to set the sensitivity, make sure that you have completed the fine adjustment process (the digital display should be “OFF”). To set the sensitivity, depress the sensitivity button once. The digital display will illuminate and read the current sensitivity setting as indicated on the chart. Continue to depress the sensitivity button until the desired setting is achieved. The display will turn off automatically. The default sensitivity will be factory set at level 4 or 50%.

In addition to the four standard sensitivity selections the detector has two Acclimate settings. When either of these settings is chosen the detector will automatically adjust its sensitivity using advanced software algorithms to select the optimum sensitivity for the environment. The sensitivity will be continuously adjusted within the ranges specified in the chart above.

STEP 4. COMPLETINg ThE INSTALLATION

Refer to Figure 13 for this step.

1. Tighten the optics lock down screws so the optics are secure. Take special care not to shift or disturb the optics. Use a hand screwdriver to avoid over-tightening or jarring the optics.

2. Install the outer housing of the detector, making sure to tighten all four screws in each corner of the housing.

NOTE: The housing contains a gasket seal that protects the detector from moisture.

3. Remove the protective film from the front surface of the outer housing.

4. Press the reset button, making sure to avoid blocking the line-of-sight between the detector and reflector. The yellow LED will begin to blink for about 20 seconds. At this time, the detector is making its final gain adjustment to compensate for the effects of installing the outer housing.

When the gain adjustment is complete, the yellow LED will turn off and the green LED will begin blinking, indicating a successful gain adjustment.

5. Install the trim ring by snapping it onto the outer housing. If the trim ring was painted, ensure that the paint is completely dry before installing.

STEP 5. fINAL vERIfICATION

1. Block the entire reflector with an opaque material. Nearly any non-reflective opaque material will do, including this manual or the cardboard packaging inserts. The detector should enter a trouble condition, indicated by the fault relay and the yellow LED (see Appendix 1) after 30 seconds. If the detector does not enter a trouble condition, there is a problem with the installation. Refer to troubleshooting section in Appendix 1 for assistance.

2. Complete a sensitivity test of the detector. Refer to the Sensitivity Testing section of this manual for the appropriate procedure.

3. Remove the orange adhesive-backed sheet used to aid in coarse adjustment.

Congratulations. You have completed the final installation and alignment procedure.

SENSITIvITy TESTINg

NOTE: Before testing, notify the proper authorities that the smoke detector system is undergoing maintenance, and therefore the system will be temporarily out of service. Disable the zone or system undergoing maintenance to prevent unwanted alarms.

Detectors must be tested after installation and following periodic maintenance.

The sensitivity of the BEAM1224/BEAM1224S may be tested as follows:

NOTE: Before testing the detector, check for the presence of the flashing green

LED at the receiver, making sure not to disturb or block the beam. If it does not flash and the detector is not in trouble or alarm, power has been lost to the detector (check the wiring).

A. Calibrated Test Filter

The sensitivity of the detector can be tested using an opaque material to cover the reflector by an amount indicated by the graduated scale on the reflector.

(Due to the high optical efficiency of the reflector the selection of the opaque material used to block the reflector is not critical. Acceptable materials include, but aren’t limited to, this manual or the cardboard packaging inserts.)

Refer to Figure 14 for this procedure.

1. Verify the sensitivity setting of the detector in % obscuration. See the

Sensitivity Selection section of this manual for sensitivity determination if sensitivity is unknown.

D400-73-00 7 I56-2294-006R

2. Place the blocking material over the reflector, lining it up with the graduated marks that are 10 less than the detector’s setting in percent obscuration. The detector should not alarm or fault. Keep the material in place for a minimum of 1 minute.

3. Place the blocking material over the reflector lining it up with the graduated marks that are 10 more than the detectors setting in percent obscuration. The detector should enter alarm within 1 minute.

4. The detector can be reset with the reset switch on the detector unit, remote reset, or momentarily interrupting power.

5. Notify the proper authorities that the system is back on line.

fIgURE 14. REfLECTOR TEST CARD PROCEDURE:

LINE UP EDGE OF

APPROPRIATE

Note: For the BEAM1224 this test does not satisfy the requirements of NFPA72 for periodic maintenance and sensitivity verification of beam type detectors.

For the BEAM1224S this test in conjunction with the complete reflector blockage test (see step 4 of the Installation/Alignment procedure in this manual) does satisfy the requirements of NFPA72 for periodic maintenance and sensitivity verification of beam type detectors.

If the detector fails this test several steps should be taken to determine if the detector is faulty or simply needs to be re-adjusted before returning the unit for repair. These steps include:

1. Verify all wiring connections and appropriate power is applied to the detector.

2. Verify that the optical line of sight is free from obstructions and reflective objects.

3. Apply the maintenance procedure in this manual. Repeat the test procedure. If the detector still fails the test procedure proceed with step 4.

4. Repeat the alignment procedure in this manual. If the alignment procedure is successful repeat the test procedure. If the detector still fails the test it should be returned.

MAINTENANCE

NOTE: Before cleaning the detector, notify the proper authorities that the smoke detector system is undergoing maintenance, and therefore the system will be temporarily out of service. Disable the zone or system undergoing maintenance to prevent unwanted alarms.

1. Carefully clean the outer housing lens face. A damp soft cloth with a mild soap may be used. Avoid products with solvents or ammonia.

2. Carefully clean the reflector. A damp soft cloth with a mild soap may be used. Avoid products with solvents or ammonia.

3. Notify the proper authorities that the system is back on line.

PAINTINg

The outer aesthetic ring may be painted using a spray or brush type paint of appropriate type. See specification section of this manual for paint types.

NOTE: Never paint the flat lens surface of the outer housing.

SPECIAL NOTE REgARDINg SMOkE DETECTOR gUARDS

Smoke detectors are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.

MOVE TEST CARD TO DESIRED AMOUNT OF OBSCURATION

C0267-00

If the detector fails this test several steps should be taken to determine if the detector is faulty or simply needs to be re-adjusted before returning the unit.

These steps include:

1. Verify all wiring connections and appropriate power is applied to the detector.

2. Verify that the optical line of sight is free from obstructions and reflective objects.

3. Apply the maintenance procedure in this manual. Repeat the test procedure. If the detector still fails the test procedure proceed with step 4.

4. Repeat the alignment procedure in this manual. If the alignment procedure is successful repeat the test procedure. If the detector still fails the test it should be returned.

B. Test Switch

The detector can be tested using the local test switch on the transmitter/receiver unit or remotely using the remote test station.

The remote test can be used with the BEAM1224/BEAM1224S beam smoke detector. Follow instructions included with the test station for proper use. See

Figure 8 (Remote Test Station) for wiring diagram.

The BEAM1224S is equipped with an integral sensitivity test feature that consists of a calibrated test filter attached to a servo motor inside the detector optics. When a test is initiated using the remote test station or local test switch the test filter is moved in the pathway of the light beam. The on-board microprocessor then determines if the proper level of signal reduction is received at the receiver. If the proper level of signal reduction is received the detector will enter alarm. If the proper level of signal reduction was not achieved, indicating that the sensitivity of the detector is out of tolerance, the detector will enter the trouble condition.

Always perform a complete reflector blockage test as in step 4 of the Installation/Alignment procedure to ensure that the pathway between the detector and reflector is clear.
