NOTICE:

This manual shall be left with the owner/user of this equipment.

Depth 2.47" (62.7mm) 2.50" (63.5mm) BEFORE INSTALLING Please read the System Sensor Audible Visible Application Reference Guide, which provides detailed information on notification devices, wiring and special applications. Copies of this manual are available from System Sensor. NFPA 72 and NEMA guidelines should be observed.

Important:

The notification appliance used must be tested and maintained following NFPA 72 requirements. GENERAL DESCRIPTION System Sensor series of notification appliances offer a wide range of audible and visible devices for life safety notification. Our 4-wire horn strobes come with 10 field selectable tone and volume combinations and 7 field selectable candela settings. Intended for indoor applications and approved for ceiling mount installations. 4-wire horn strobes and strobes are public mode notificati2on appliances in tended to alert occupants of a life safety event. The horn is listed to ANSI/ UL 464 requirements (public mode) and the strobe is listed to ANSI/UL 1638 (public mode). System Sensor strobes are designed to be used in 12 VDC, 24VDC, or 24V FWR (full wave rectified) systems. System Sensor AV devices can be activated by a compatible fire alarm control panel or power supply. Refer to the appropriate fire alarm control panel manufacturer or power supply for more information. System Sensor ceiling 4-wire horn strobes are electrically backward compat ible with the previous generation, since 1996, of notification appliances. They come enabled with System Sensor synchronization protocol which requires connections to a power supply capable of generating the System Sensor syn chronization pulses, a FACP NAC output configured to System Sensor synchro nization protocol, or the use of MDL3 module to generate the synchronization protocol. FIRE ALARM SYSTEM CONSIDERATIONS The National Fire Alarm and Signaling Code, NFPA 72, requires that all noti fication appliances, used for building evacuation installed after July 1, 1996, produce temporal coded signals. Signals other than those used for evacuation purposes do not have to produce the temporal coded signal. System Sensor recommends spacing notification appliances in compliance with NFPA 72. MOUNTING BOX OPTIONS 4-wire Indoor Products 4" x 4" x 1½", Double Gang, 4" Octagon, SBBCRL/WL (ceiling) SYSTEM DESIGN The system designer must make sure that the total current draw by the devices on the loop does not exceed the current capability of the panel supply, and that the last device on the circuit is operated within its rated voltage. The current draw information for making these calculations can be found in the tables within the manual. For convenience and accuracy, use the voltage drop calculator on the System Sensor website (www.systemsensor.com).

When calculating the voltage available to the last device, it is necessary to consider the voltage due to the resistance of the wire. The thicker the wire, the smaller the voltage drop. Wire resistance tables can be obtained from electri cal handbooks. Note that if Class A wiring is installed, the wire length may be up to twice as long as it would be for circuits that are not fault tolerant. The total number of strobes on a single NAC must not exceed 69 for 24 volt applications.

AVAILABLE TONES System Sensor offers a wide variety of tones for your life safety needs, includ ing temporal 3 pattern (½ second on, ½ second off, ½ second on, ½ second off, ½ second on, 1½ off and repeat) which is specified by ANSI and NFPA 72 for standard emergency evacuation signaling. To select the tone, turn the rotary switch on the back of the product to the desired setting. (See Figure 1.) Available horn settings can be found in Table 1. NOTE: The standard mini-horn sound is 3.1 kHz. The legacy sound of the SpectrAlert Advance line is EM (Electro-mechanical): this hops frequencies between 2Hz and 4Hz. For EM Coded positions, temporal coding must be provided by the NAC. If the NAC voltage is held constant, the horn output will remain constantly on.

WIRING AND MOUNTING All wiring must be installed in compliance with the National Electric Code and the local codes as well as the authority having jurisdiction. Wiring must not be of such length or wire size which would cause the notification appli ance to operate outside of its published specifications. Improper connections can prevent the system from alerting occupants in the event of an emergency.

Wire sizes up to 12 AWG (2.5 mm²) may be used with the mounting plate. The mounting plate ships with the terminals set for 12 AWG wiring. Make wire connections by stripping about 3 / 8 "of insulation from the end of the wire. Then slide the bare end of the wire under the appropriate clamping plate and tighten the clamping plate screw. We provide a wire strip guide. See Figure 6 for wiring terminals and strip guide reference.

CAUTION

Factory finish should not be altered: Do not paint!

CAUTION

Do not over tighten mounting plate screws; this may cause mounting plate to flex.

WARNING

THE LIMITATIONS OF HORN/STROBES

The horn and/or strobe will not work without power.

The horn may not be heard.

The horn/strobe gets its power from the fire/security panel monitoring the alarm system. If power is cut off for any rea son, the horn/strobe will not provide the desired audio or visual warning.

The loudness of the horn meets (or exceeds) current Underwriters Laboratories’ standards. However, the horn may not alert a sound sleeper or one who has recently used drugs or has been drinking alcoholic beverages. The horn may not be heard if it is placed on a different floor from the person in hazard or if placed too far away to be heard over the ambient noise such as traffic, air conditioners, machinery or music appliances that may prevent alert persons from hearing the alarm. The horn may not be heard by persons who are hearing impaired.

NOTE:

Strobes must be powered continuously for horn operation.

The signal strobe may not be seen.

impaired.

The electronic visual warning signal uses an extremely reliable xenon flash tube. It flashes at least once every second. The strobe must not be installed in direct sunlight or areas of high light intensity (over 60 foot candles) where the visual flash might be disregarded or not seen. The strobe may not be seen by the visually

The signal strobe may cause seizures.

Individuals who have positive photoic response to visual stimuli with seizures, such as persons with epilepsy, should avoid prolonged exposure to environments in which strobe signals, including this strobe, are activated.

The signal strobe cannot operate from coded power supplies.

Coded power supplies produce interrupted power. The strobe must have an uninterrupted source of power in or der to operate correctly. System Sensor recommends that the horn and signal strobe always be used in combination so that the risks from any of the above limitations are minimized.
