Installation instructions are provided in the first part of the manual with the following sections dealing with commissioning, full technical details and operating procedures. A separate Log Book is also provided. System Design and Planning It is assumed that the system, of which this control panel is a part, has been designed by a competent fire alarm system designer in accordance with BS 5839-1:2002 and with regard to BS EN 54 parts 2 and 4 in the case of control equipment and power supplies. Design drawings should be provided to clearly show the position of any field devices and ancillary equipment. Panel Types FCPENV-1 A single zone, non extendable control panel with an integral 1.0 Amp PSU and space for 2 x 12V S.L.A batteries. Cabinet size: 277mm Wide x 200mm High x 97mm Deep FCPENV-1EXT A single zone control panel with the capacity to be extended up to 4 zones via plug in zone cards. Integral 1.0 Amp PSU and space for 2 x 12V S.L.A batteries. Cabinet size: 400mm Wide x 200mm High x 97mm Deep. FCPENV-1EXT-L As above but in larger cabinet to allow batteries to be fitted without removing the PCB. Cabinet size: 400mm Wide x 300mm High x 97mm Deep. General The control panel is a micro-processor controlled, conventional fire alarm control system, comprising of one circuit board, plus add on modular circuit boards, for additional zones (extendable version only). The enclosure consists of back box and hinged, removable lid. Constructed of 1.2mm (18swg) zintec mild steel and powder coated in textured light grey. The enclosure is designed to give protection to IP30 level. Control panels are available from 1 to 4 zones. They are supplied as a one zone non extendable control panel or a one zone extendable control panel. The panel is extended using either the hy-spec single zone cards, which consist of one zone, one sounder circuit and one aux relay, or a three zone budget zone card which consists of just three zones on a single card plus zone +ve for 3 wire connections. A 4 zone repeater is available and requires one core per zone plus three additional cores. These panels are designed to comply with the requirements of BS EN 54 part 2 1998, but include integral facilities to enable connection to older systems, which may not comply with current standards. Envoy Installation, Commissioning & Operating Manual 4 General – Continued The control panels are compatible with a wide range of detection and alarm devices. Refer to technical specification for details. The panel can be, CONVENTIONAL with separate detection and alarm circuits or “TWIN-WIRE“, with detectors and sounders on the same circuits. This is selectable internally and can be set differently for each zone if using the hy-spec single zone extension cards. The ENVOY control panel has integral detector removal monitoring and no special active end of line units are required. ENVOY control panels are simple to install and operate. Control functions are enabled by keyswitch. The panel fascia is retained by a security cam lock . No internal access is required under normal usage. SECTION 2 – INSTALLATION General • The installation of fire detection and alarm systems should be carried out in accordance with B.S.7671, IEE wiring regulations and in line with B.S.5839 British Standard codes of practice for fire alarm installations. The installation should be carried out by suitably qualified and experienced technicians. • Care should be taken with regards to avoiding the close proximity of high voltage cables or areas likely to induce electrical interference. Earth links should be maintained on all system cables and grounded in the control panel. • Any junction boxes used should be clearly labelled FIRE ALARM. • Any ancillary devices, e.g. door retaining magnets, must be powered from a separate power source. • Any coils or solenoids used in the system must be suppressed, to avoid damage to the control equipment. Envoy Installation, Commissioning & Operating Manual 5 ESD PRECAUTION Electronic components are vulnerable to damage by Electrostatic Discharges (ESD). An ESD wrist strap, suitably grounded, should be worn at all times when handling pcbs. These wrist straps are designed to prevent the build up of static charges, not only within a persons body, but on many other materials. ESD damage is not always evident immediately, faults can manifest themselves at anytime in the future. All pcbs should be stored in static shielded bags (silvered) for safe keeping, when not mounted in the control panel. Do not use “black” or “pink” bags and never allow pcbs to come in contact with bubble wrap or expanded polystyrene (packing chips). Static shielded bags and disposable wrist straps are available from the manufacturer. ! Warning, Control Panel Access Keys The keys to the control panel must be kept, safely, by a responsible person. Hazardous voltages may be present. Access to the inside of the panel is not normally required. Disconnect mains supply prior to opening cabinet. Cable Types and Limitations To comply with EMC (Electro Magnetic Compatibility) regulations and to reduce the risk of electrical interference in the system wiring, we recommend the use of screened cables throughout the installation. Acceptable, commonly available, screened cables, which can be used on both the sounder and detector circuits include NoBurn™, FP200™, Firetuff™, Firecel™, or any other cable complying with BS 6387 categories C, W, Z. Mains Wiring The mains supply to the fire alarm panel should be hard wired, using suitable three core cable (no less than 1.0mm2 and no more than 2.5mm2) or a suitable three conductor system that meets the appropriate national wiring regulations. The panel should be fed from a double pole, isolating, switched, fused, spur, fused at 3A. This should be secure from unauthorised operation and be marked ‘FIRE ALARM: DO NOT SWITCH OFF’. The mains supply must be exclusive to the fire panel. As an alternative to a switched fused spur, a double pole isolating device may be used (see diagram) providing it meets the appropriate national wiring regulations. NOTE: Any isolating device used, must have a minimum 3mm contact gap. Envoy Installation, Commissioning & Operating Manual 6 Planning the Cable Layout in the Panel The detector and sounder circuit cabling is classed as extra low voltage and must be segregated away from mains voltages. Careful planning is needed to ensure this, refer to Figure 1 (below) for guidance and important information on how to remove the panel’s knockouts. Always ensure that if a knockout is removed, the hole is filled with a good quality cable gland. Any unused knockouts must be securely blanked off. Figure 1 : Location of knockouts for cable entry and knockout removal details Fixing the Cabinet Remove outer cover by unlocking the door, drop down fully, remove Earth connection, slide lid to the right, then pull gently towards you. Disconnect transformer and earth connections at top l/h corner of PCB using small terminal driver. The terminals are marked ac (white wires) and Earth (green and yellow wires). Remove circuit board from back box by unscrewing 3 in number M4 cross headed screws from the circuit board supports. Place circuit board, lid and fixings in a safe position. Secure cabinet to the wall using the four indented holes in the back box (see figure 2). Ensure that the box is mounted in a convenient location where it may be easily operated and serviced and where it is away from possible sources of vibration or shock, i.e., on partition wall next to a slamming door. External cables should be glanded via pre-formed knockouts at the top and rear of the box as provided. The enclosure should be cleaned of swarf etc., prior to refitting of printed circuit board. Disconnect the battery leads from the circuit board by a pull out connector at the top l/h corner of the PCB. Insert batteries and connect the battery leads to the battery terminals before replacing circuit board. Ensuring the white link lead is also connected. Figure 2 : Fixing the cabinet (Drawing shows model FCPENV-1 with 2 x 4.5Ah, 12v batteries). (Models FCPENV-1EXT and FCPENV-1EXT-L have space for up to 2 x 7.0Ah, 12v batteries) Envoy Installation, Commissioning & Operating Manual 7 Additional Zone Cards If fitting additional zone cards to the extendable version of the ENVOY control panel, first refit the main circuit board. Slide additional cards into position using the locating pins, see figure.3. Particular attention must be made to ensuring that the pins are located correctly in the connector. Misalignment of these pins will result in damage to the zone card when the panel is powered up, see figure.4. Fix the card into position using clips and self tapping screws provided. Pre-drilled fixing holes have been made in the mounting rail but they are obscured by a foam strip which is designed to protect tracks on the back of the zone card. It is advisable to locate these fixing holes before attempting to screw down the circuit board. Mains Connections The general requirements for mains wiring is described on page 6. Do not connect the mains supply to the panel until you are fully conversant with the layout and features of the equipment. A rating plate is fitted in the bottom left hand corner of the panel describing the nature of the supply permitted. The incoming mains supply should be brought into the panel in the bottom left hand corner, via the knockout provided. A suitable cable gland must be used to secure the outer sheath of the cable used. The earth must first be connected to the primary earth stud (peg) marked with a crimp provided. symbol using ring Sufficient earth lead should be left to allow Live and Neutral connections to be accidentally pulled from terminal block, while leaving earth connection intact. Secondary earths may be connected to the brass earthing block.

This method of wiring does not meet current standards for new systems, but may be suitable for upgrading certain existing installations. Three wire circuits may contain high current and / or unpolarised sounders or other unsuitable equipment, so care should be taken to upgrade equipment when connecting in these circuits. CAUTION: Ensure all solenoids, relays and sounders fitted to the circuits are polarised and suppressed with back EMF diodes. It is recommended that old heavy current sounders are changed to light current. Maximum sounder load on the total 3 wire system is 1 Amp. The following modifications must be made for the circuit to function correctly: • The detector zone must be configured for short = fire and no head removal monitoring by switching SW4 on DIL switches. Refer to Engineering Options. • The sounder circuit is not monitored, therefore a 4K7 resistor must be fitted to the sounder circuit terminals in the panel.

By following a logical sequence any faults that may occur can be quickly identified and rectified before moving on to the next step. Before connecting external circuits to the control panel it is recommended that the panel is powered up and tested, and any faults cleared before proceeding. Ensure that 4K7 resistors are fitted into zone and sounder circuit terminals (see drg.no. S1597 on page 10) before applying power. To clear the battery fault indication when the mains is connected, a battery must be connected to the battery terminals; it is not possible to inhibit the battery fault by the insertion of a resistor. The system may be operated on the battery supply, i.e. if the mains supply is not available. Powering the Panel Remove the fuse from the mains input. Connect the supply wiring to the terminal block. Check that all connections are sound and that 4K7 EOL resistors are fitted to zone and sounder circuits. Refit the fuse and switch on the mains supply. The panel LEDs are illuminated momentarily, the ARW LED remains lit and a battery fault is indicated. The internal buzzer sounds. Connecting the Battery The standby battery comprises two 12V cells of a capacity suitable for the required standby period and total alarm load. Batteries may be located in the panel or in a separate cabinet depending on the battery size. Battery leads are provided, including a battery link. The SUPPLY HEALTHY LED should now be illuminated. The ARW LED should be illuminated and the internal buzzer pulsing. Turn the CONTROLS keyswitch to ON, and press RESET. All the LEDs are lit momentarily, the ARW LED should extinguish and the buzzer should be silent. The panel is now operating correctly in the quiescent mode. Any faults that are indicated at this stage should be investigated and cleared before proceeding. If necessary refer to the fault location chart on page 22 for further information. If unfamiliar with the Surveyor ENVOY Series equipment, it is advisable to explore the panel operation and become conversant with the controls before proceeding. Faults can be simulated by open and short circuiting zone and sounder circuits, fire alarms can be generated by shorting the zone terminals with a 470R resistor. Refer to the Operation section if required. Disposal of Batteries Respect the environment. Batteries must be disposed of responsibly and in accordance with any local regulations. Envoy Installation, Commissioning & Operating Manual 17 Initialisation of Zone Cards For added security, the master card (PCENV-M-5) keeps a log of fitted zone cards and will indicate a system fault, with a warbling tone, if zone cards are removed, or cease to function. To achieve this, zone cards are logged ‘on’ and ‘off’ of the panel. Proceed as follow: 1 Ensure panel is completely powered down by disconnecting both mains and battery supplies. 2 Insert, or remove, required zone card(s), ensuring pins are securely located. 3 Press and hold button No.1 on keypad and at the same time apply either battery or mains power. 4 Observe the zone fault illuminating on each zone card, this indicates acknowledgment of ‘learning’ mode. 5 Release button 1 and press Reset to clear fault indications and ‘ARW’. If a panel should start to warble and show system fault, check the following:• If a PCENV-NET card is fitted, refer to network instructions. • If no network is present, check whether zone cards will function i.e. go into fire, or fault. • If a zone card appears to be faulty, replace it, or remove it. • If a problem persists, try to re-log the card by following the procedure 1-5 again, as above. • If ‘Disablement’ indicator is on, but no zone is illuminated, it is possible that the internal memory is out of synchronisation. This can be corrected by the following procedure: 1 Completely power down panel 2 Press and hold button No.2 on keypad whilst powering up 3 The panel will enter a self diagnosis mode, which resets the memory 4 Pressing the ’Enter’ button will step through a test routine, which will operate LEDs and outputs in a sequence. To exit this mode, power down the panel and power up again, as normal. Envoy Installation, Commissioning & Operating Manual 18 Twin Wire Operation The panel can be converted to ‘Twin Wire’ operation by selecting Dil switch 5 on each zone card (hyspec zone cards only). Any individual zone, or all zones , can be selected as twin wire. The twin wire is designed to operate with polarised 470R call points, Apollo and Hochiki ‘SAV-WIRE’ bases only. See page 24 for part No.s. Any standard 24v bell, siren or strobe, that is polarised and suppressed can be used, providing sounder o/p limits are not exceeded. Short circuit as fire and non latching zones cannot function on a twin wire zone. When twin wire operation is selected, the conventional zone circuit is disabled by the software. The sounder CCT terminals should be used for connection of detectors, call points and sounders. When used as a twin wire system, use sounder 1 on the main card (PCENV-M-5) and remove the 4K7 resistor in sounder 2, to enable correct monitoring, as these circuits work in tandem. Where a single zone twin wire system is installed (normally non compliant) and two sounder outputs are required the following modification can be employed: Remove both 4K7 EOL resistors from SNDR 1 and 2 and substitute with 10K ohm resistors (or 2 x 4K7 in series). This enables sounders and / or detectors to be used on both legs to provide 2 monitored circuits on one zone, thus enabling full compliance for twin wire, with only one zone. Envoy Installation, Commissioning & Operating Manual 19 Zone Circuits The default mode of operation assumes that the zone circuit is configured for open and short circuit fault monitoring, and detector removal monitoring, i.e. detector bases are fitted with a diode. If these conditions do not apply, e.g. when connecting a circuit from an existing system, the operating parameters for each affected zone must be changed. Refer to the Engineering Options section for details. It is recommended that each zone is connected in turn and its operation proved before moving on to the next zone. Check that all detectors are fitted into their bases and that a 4K7 Ohm resistor has been fitted to the last device. Remove the 4K7 Ohm resistor from the selected zone terminals and connect the zone pair, observing polarity. If a zone fault is indicated, investigate and clear before proceeding to the next circuit. If necessary refer to the fault location chart on page 22. Continue to connect each zone circuit until all are connected and fault free. It may be preferable to test the operation of zone devices before proceeding with the connection of sounders. Sounder Circuits The Master PCB has two sounder circuits and each hy-spec zone card has one sounder circuit that by default operate in “constant sounder” mode on the activation of any zone. “ Zone of origin operation” can be achieved by changing the operating parameters. Refer to Engineering Options. Sounders must be polarised and suppressed and connected in a parallel circuit with no spurs or tees. Ensure that the load of the sounders is within the individual circuit limits, and that the total load does not exceed the panel limits, taking into account any additional load imposed by auxiliary circuits, repeaters, etc. Remove the 4K7 Ohm resistor from the relevant sounder circuit terminals and connect the circuit pair, observing polarity. Ensure that a 4K7 Ohm resistor is fitted in parallel with the last device on the circuit. Clear any faults before proceeding – refer to the fault location chart on page 22 if necessary. Sounders can be tested by operating the SOUND ALARMS push button. Three-wire Circuits (budget pcb only) A typical connection for a three-wire circuit is shown in drg. no. S1599 (page 12); however, the following modifications need to be made for the circuit to function correctly: • The detector zone must be configured for Short = Fire, unless the circuit is compatible with open and short circuit monitoring, i.e. detectors with an alarm impedance of > 100 Ohm and < 700 Ohm are fitted, and call points are fitted with a 470 Ohm series resistor. Refer to Engineering Options. • In these circumstances the sounder circuit is not monitored, therefore, a 4K7 Ohm resistor must be fitted at the sounder circuit terminals. Envoy Installation, Commissioning & Operating Manual 20 SECTION 5 – FAULT FINDING General A fault is indicated by the illumination of the SYSTEM FAULT LEDs and a buzzer tone. Specific faults are identified by additional fascia indicators, e.g. zone fault. The buzzer tone varies depending on the fault and may, or may not, be silenceable. Fault Latch If an intermittent fault exists it is possible to make all fault indications latch to help identify problems. To activate fault latch press the TEST MODE button and then the ENTER button. The Test Mode LED will be lit but no buzzer sounds. Any faults occurring while this mode is active will be latched until the RESET button is pressed. Pressing RESET at any time will exit fault latch mode. Envoy Installation, Commissioning & Operating Manual 21 Fault Finding Chart The following chart identifies the indications that may be displayed, with the possible cause and the recommended action. Fault location should be tackled logically by isolating fault paths until the source is apparent, e.g. disconnecting zone and sounder circuits to prove if the fault is on the circuit or in the panel, etc. Faults on external circuits can be traced by breaking down the circuit, e.g. placing the EOL at the mid point of the circuit and determining which half is affected. Panel Indication Possible Cause Action Supply Healthy extinguished. No other indications Mains failure & Battery failure Check supply / fuse Check battery / fuse Change batteries Apply Mains System Fault + PSU fault Mains failure/fuse failure Battery disconnected or open circuit. Battery Fuse failed Voltage too high (>30V) or too low (<19V) Check supply / fuse Check battery / fuse Adjust to 27.6V. Measure voltage using the battery terminals on pcb, with the batteries disconnected. System Fault + Earth fault One or more cables in contact with earth Disconnect ext. cables until fault clears. Investigate circuit and rectify. If fault persists with all circuits disconnected, then fault is on PCB. Replace. Hint: Remove the pcb to earth block earth wire, if the fault dissapears then you have an earth fault. If not the fault is on the pcb. System Fault + Sounder fault Sounder circuit open circuit (LED slow Check circuit integrity/EOL pulse) or short circuit (LED fast pulse) Sounder not polarised or reverse polarity – correct fault System Fault + Zone Fault Zone open circuit (LED slow pulse) Zone short circuit (LED fast pulse) Confirm fault is on external circuit by disconnecting zone wires and fitting 4K7R in zone terminals.

All standard panels of verion 5.0 and above can be networked. The PCENV-NET is an ‘add-on’ card which provides the RS 485 interface and address switches. A PCENV-NET is required for each panel in the network. Up to four panels can be networked. A ‘comms’ terminal is provided on the master pcb as standard (although this is not shown on the schematic diagrams on the previous pages), but this terminal is not active without the network card fitted. Network Philosophy Up to four standard panels can be connected. 1 way or 3 way zone cards can be used in any combination. Ideally on a four zone system, four indicating zones must be available. Several interesting scenarios can be achieved: 1. A simple panel with up to three repeaters 2. Connect two zones on one panel two on the other and both panels will show all four zones 3. Connect one zone on each of four panels and display all zones on all panels 4. Have zones on one panel and sounders on another Other permutations are possible. Limitations The system is limited to four zones, although sixteen could be connected, only four can show at one panel. For example, when zone 1 is put into fire, it will display as zone 1 on all panels regardless of which panel zone 1 wiring is connected to. Installing PCENV-NET 1. Turn off power to panel 2. Remove PCENV-M (Master pcb) 3. Locate mounting hole and fit small 3mm threaded spacer (supplied) to PCENV-M. Make sure insulated washer (supplied) is used under screw head. 4. Plug in PCENV-NET to 10 way header, (see drawing1832M) ensure alignment with small spacer and check all connector pins are aligned correctly. 5. Fit screw through PCENV-NET into spacer and tighten to secure pcb. 6. The communications cable is connected to ’comms’ terminals at top of pcb (see drawing 1831M) Envoy Installation, Commissioning & Operating Manual 25 Set Up Network Once all cards are fitted , set Dil switch addresses on PCENV-NET. Designate one panel as the ‘master’ Dil switch positions:Both off 1 off 2 on 1 on 2 off 1 on 2 on = = = = Master First repeater / panel Second repeater / panel Third repeater / panel Each panel must have a different setting. For monitoring purposes, the master must be instructed how many panels are in the network. If it changes, the panel will show system fault and will warble. To enter quantity of panels: At the master panel (panel with both address switches ‘off’) 1. Turn off power to panel 2. Press and hold button 4 on keypad whilst powering panel back up. (when powered up the panel will beep continuously) 3. Enter total number of panels in the network, including the master, by pressing the relevant keypad number (1-4), followed by the enter button. When all panels are addressed correctly, the master is set-up and all panels are powered, the TX and RX LEDs will flicker on all panels to confirm communication between panels. In the event of a ‘comms’ failure the affected panels will warble and show a fault. Note:- panels will function as stand alone in the event of ‘comms’ failure. Network Control and Operation As standard, the network / repeater panels are configured to provide basic operation. If non standard functioning is required, please contact our technical department for advice. The table below details the functionality of the system.

The sounders on panel A will sound continuously only when an alarm is received from one of ‘A’s zones. With due consideration at the design stage, networking could provide useful solutions. Please contact our technical department for further advice.

Envoy Installation, Commissioning & Operating Manual 32 Test Mode ZONE TEST To put zone(s) into test mode, turn the Activate Controls key-switch to the ON position and press the TEST MODE button on the keypad. Now use buttons 1 – 4 to select which zone(s) to put into test mode and press ENTER when all selections have been made. The test mode entry will “time out” within 5 seconds if the ENTER button is not pressed. It is possible to have any or all zones in test mode at the same time. The Test Mode and Common Fault LEDs will be pulsing. The fault LED of the zone(s) in test mode will be illuminated and the internal buzzer will be sounding. The operation of any smoke detector or call point will now ring all bells or sounders for one second. The panel will automatically reset, providing that the detector is clear of smoke or the call point glass is back in position. The alarms will then sound momentarily to acknowledge that the panel has reset, so you can move on to the next device. Press the RESET button on the keypad at any time to exit Test Mode. The removal of a detector while in test mode will also cause the alarms to sound for one second and then again momentarily when the detector is replaced, thus enabling a Detector Removal Monitoring Walk Test. N.B the panel may take a few seconds to recognise a detector has been removed due to it’s normal monitoring cycle. ZONE TEST WITHOUT SOUNDERS To test zones without the operation of any sounders, i.e. visual indications and panel buzzer only. Press the TEST MODE button on the keypad followed by buttons 1 – 4 to select the zone(s) to put into test. Then press the SILENCE ALARMS button and then ENTER. The sounders will now be disabled during all testing. Should a zone which is not in test go into alarm the sounders will operate as per normal. SOUNDER WALK TEST A sounder test can be activated by using the SOUND ALARMS button instead of buttons 1 – 4. This will cause the panel to sound all the bells for one second every eight seconds, allowing the user to walk to each sounder to check that it is working correctly. Remember to push each button slowly and deliberately. There is a half second delay on the buttons to prevent misuse. The panel will bleep to acknowledge each push of the button. Envoy Installation, Commissioning & Operating Manual 33 Disable Zones or Sounders DISABLE ZONES To disable / isolate zones , turn the Activate Controls key-switch to the ON position and press the DISABLE button on the keypad Now use buttons 1 – 4 to select which zone(s) to disable and then press ENTER when all selections have been made. The disable mode will “time out” within 5 seconds if the ENTER button is not pressed. It is possible to select any, or all zones, to be isolated at the same time. The disable LED will be illuminated, the common fault LED’s will be pulsing. The fault LED of the zone that is disabled will be illuminated and the internal buzzer will be sounding. DISABLE SOUNDERS To disable sounder circuits press the SOUND ALARMS button instead of buttons 1 – 4 (see above) and then press ENTER. The sounder fault LED will be illuminated. It is not possible to select individual sounder circuits.This routine will disable all sounder circuits. To enable the zones or sounder circuits again simply repeat exactly the same procedure. WARNING zones and sounder circuits that have been disabled cannot be enabled by the use of the RESET button. Remember to push each button slowly and deliberately. There is a half second delay on the buttons to prevent misuse. The panel will bleep to acknowledge each push of the button. Envoy Installation, Commissioning & Operating Manual 34 Routine Maintenance and Testing It is essential that the fire alarm installation is checked regularly by a responsible person for correct operation in accordance with EN54 Part 2 or BS5839 Part 1. or applicable standard. CLEANING The exterior of the cabinet may be cleaned when required using a clean, moistened cloth. Do not use solvents or abrasives as these will damage the panel. ROUTINE TESTING Routine checks should be carried out as detailed in this section of the manual. It is essential to keep the log, in order to maintain a record of tests, checks, alarms and faults. A log book is provided with this instruction manual. The log book should be kept with the panel and be available for inspection by an authorised person. DAILY Check that the green, “SUPPLY HEALTHY“, indicator is lit. If the indicator is not lit, record the fact in the log book and call for a qualified electrician to check the power supply. WEEKLY Carry out the daily check. Operate one detector or call point on one zone and check that the panel responds to the alarm and operates the warning devices. Record the results of the test and the zone detector/call point operated, in the log book. A different zone detector/call point should be operated each week, to ensure that all detectors/call points are tested in turn. Visually inspect the batteries and all connections and ensure that they are in good condition. Visually inspect all call points and detectors and ensure that none is, in any way, obstructed or damaged. QUARTERLY Check all previous entries in the log book and ensure that all necessary remedial action has been carried out. Carry out the daily check. Carry out the weekly test. Isolate the mains supply, then test that the battery is capable of operating the warning devices by operating a detector or call point. Reconnect the mains supply. Record the results of the tests in the log book. ANNUALLY Carry out the daily, weekly and quarterly tests. Test all the detectors and call points for correct operation. Visually inspect all cable fittings and equipment to ensure that they are secure, undamaged and adequately protected. Record the results in the log book. EVERY 5 YEARS Renew the sealed lead acid batteries and record the fact in the log book. The installation requires to be tested in accordance with the testing and inspection requirements of the Local or National Standards. Any defect should be recorded in the log book and action should be taken to correct it. DETECTORS Renew or return the smoke detectors for cleaning, as directed in the manufacturer’s data, to ensure correct operation and freedom from false alarms. Cleaning smoke detectors is a specialised activity. If in doubt consult the supplier. Record the actions in the log book. NOTE: Ionisation smoke detectors contain a radioactive source and should only be disposed of in the recommended manner. Contact your Service Company for further advice. Envoy Installation, Commissioning & Operating Manual 35 USER INSTRUCTIONS Alarm Condition If all the sounders or bells are ringing, the system is in an alarm condition. YOU MUST EVACUATE THE BUILDING OR FOLLOW YOUR NORMAL FIRE DRILL PROCEDURES. A responsible person should then:1 2 3 4 Check the control panel to see which area or zone has caused the system to go into alarm. The zone in alarm will be indicated by a red light on the front of the control panel, see fig 1. Go to the area which has caused the alarm to check if a fire exists. Only when it is safe to do so should the alarms be silenced. Turn the “activate controls” keyswitch to the ON position and press the SILENCE ALARMS button, see fig 2. If it was a false alarm look for the device that has caused the alarm. A detector will have a red light lit, or check to see if a call point glass is broken. (If so replace the glass or call an engineer.) When fully satisfied that there is no fire, return to the control panel and press the RESET button, see fig 3. Once the system has been reset the light on the detector should extinguish and only the green SUPPLY HEALTHY lamp should be lit on the control panel. If the system continues to false alarm, call an engineer. Fault Condition If a buzzer is sounding in the control panel but the sounders or bells are not ringing, then there is either a fault on the system or zones / sounders have been disabled. Call an engineer. The internal fault buzzer can be silenced by pressing the ENTER button. DO NOT RESET THE SYSTEM UNTIL AN ENGINEER HAS INVESTIGATED THE FAULT. See relevant section in the installation and operating manual for details of disabling and enabling zones and sounders.
