Before Installing

Please read the System Sensor Voice Evacuation Application Guide, which provides detailed information on speaker notification devices, wiring and special applications. Copies of this manual are available from System Sensor. NFPA 72 and CAN/ULC-524 guidelines should be observed. System Sensor also recommends installing fire alarm speakers in compliance with NFPA 72, NFPA 70, NEC 760, CAN/ULC-524 and Canadian Electrical Code.
Important: The notification appliance used must be tested and maintained following requirements of NFPA 72 in UL applications or CAN/ULC-S536 in ULC applications.

General Description

System Sensor series of notification appliances offer a wide range of audible and visible devices for life safet notification. Our indoor speaker strobes come with 7 field delectable Mandela settings. The strobe portion is designed to be used in 24VDC systems. The speaker is designed to be used at either 25 or 70.7 volts, and operate at any one of four input power levels. Our speaker strobes are suitable for dry environments. The devices are intended for indoor applications and approved for wall mount and ceiling-mount installations. These products are electrically backwards compatible with the previous generation of System Sensor speaker strobes. With its low total harmonic distortion, the System Sensor L-Series Speakers offer high fidelity sound output.
Speakers Strobes are public mode notification appliances intended to alert occupants of a life safety event. The speaker is listed to ANSI/UL 1480/ULC 541 (public mode) and the strobe is listed to ANSI/UL 1638/ULC 526 (public mode).
System Sensor amber lens ALERT Speakers Strobes are private mode notification appliances intended to alert trained personnel to investigate a life safety event. The speaker is listed to ANSI/UL 1480 (public mode) and the strobe is listed to ANSI/UL 1638 (private mode).

Fire Alarm System Considerations

System Sensor recommends spacing notification appliances in compliance with NFPA 70 and NFPA 72 (UL applications) or CAN/ULCS524 (ULC applications).
System Sensor also recommends installing fire alarm speakers in compliance with NFPA 70, NFPA 72, and NEC 760.
(CAN/ULC-S524 in ULC applications).

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 electrical 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. Total number of strobes on a single NAC must not draw more current than supported by the Fire Alarm Control Panel (FACP).

Installation

Wiring and Mounting
All wiring must be installed in compliance with the National Electric Code (UL applications), (Canadian Electric Code (ULC applications), and local codes as well as the authority having jurisdiction. Wiring must not be of such length or wire size which would cause the notification appliance 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 field wiring.

Make wire connections by stripping about 3/8″ of insulation from the end of the field wire. Then slide the bare end of the wire under the appropriate clamping plate and tighten the clamping plate screw. NOTE: Do not loop electrical wiring under terminal screws. Wires connecting the device to the control panel must be broken at the device terminal connection in order to maintain electrical supervision.
See Figure 6 for detailed wiring connections; see Figure 5 for location of terminals, shorting spring, and wire strip guide.

Wiring Diagrams

Shorting Spring Feature. These devices enable system continuity checks of field wiring before appliances are installed. The mounting plate has a shorting spring between terminals 2 and 3 that will automatically disengage when the product is installed, to enable supervision of the final system. ( See Figure 5.)

WARNING

THE LIMITATIONS OF SPEAKERS

Always make sure that the individual speakers are tested after installation per NFPA regulations. The speakers may not be heard. The loudness of the speaker meets (or exceeds) current Underwriters Laboratories’ standards.
However, the speaker may not alert a sound sleeper or one who has recently used drugs or has been drinking alcoholic beverages. The speaker 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 speaker may not be heard by persons who are hearing impaired.

WARNING

THE LIMITATIONS OF STROBES

The strobe will not work without power. The strobe gets its power from the fire/security panel monitoring the alarm system. If power is cut off for any reason, the strobe will not provide the desired audio or visual warning.
The signal strobe may not be seen. The electronic visual warning signal uses LEDs with associated lens system. 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 impaired.

The signal strobe may cause seizures. Individuals who have positive phototropic 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 order 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 minimised.
