BEFORE INSTALLING

Please read the System Sensor Audible Visible Application Reference Guide,

which provides detailed information on notification devices, wiring and spe-

cial 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 2-wire horn strobes, chime

strobes and strobes come with 8 field selectable tone and volume combina-

tions and 7 field selectable candela settings. Intended for indoor applications

and approved for ceiling mount installations.

2-wire horn strobes and strobes are public mode notification appliances in-

tended to alert occupants of a life safety event. The 2-wire chime strobe is

a private mode notification appliance. The horn is listed to ANSI/UL 464 re-

quirements (public mode) and the strobe is listed to ANSI/UL 1638 (public

mode). 2-wire chime strobe is a private mode notification appliances intended

to alert trained personnel to investigate a life safety event and take appropriate

actions. The chime portion of the chime strobe is listed to ANSI/UL 464 (pri-

vate mode) and the strobe portion is listed to ANSI/UL 1638 (private 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 2-wire horn strobes, 2-wire chime strobes, and strobes

are electrically backward compatible with the previous generation, since 1996,

of notification appliances. They come enabled with System Sensor synchro-

nization protocol which requires connections to a power supply capable of

generating the System Sensor synchronization pulses, a FACP NAC output

configured to System Sensor synchronization 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.

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.

Available chime settings can be found in Table 2.

AVAILABLE CANDELA SETTINGS

System Sensor offers a wide range of candela settings for your life safety

needs. In order to select your candela output, adjust the slide switch on the

rear of the product to the desired candela setting on the selector switch. (See

Figure 2.)

The candela setting can also be verified by looking into the small window on

the front of the unit. See Table 3 for candela settings for ceiling products. All

products meet the light output profiles specified in the appropriate UL Stan-

dards. (See Figures 3 to 5.)
