NOTICE: This manual shall be left with the owner/user of this equipment.
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.
CAN/ULC S524 guidelines should be observed.
Important: The notification appliance used must be tested and maintained
following CAN/ULC S536 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 wall
mount installations only.
The horn is listed to CAN/ULC S525 and the strobe is listed to CAN/ULC
S526.
System Sensor notification appliances are designed to be used in either 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 wall 4-wire horn strobes are electrically backward compatible 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 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 Building Code of Canada requires that all notification appliances, used for building evacuation 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 CAN/ULC S524.
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.
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, including 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 National
Building Code of Canada 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.

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 2 for candela settings for wall products. All

CURRENT DRAW AND AUDIBILITY RATINGS
The 4-wire device provides two independent circuits, one for the Horn and
another for the Strobe. The current draw for each Strobe setting is listed in
Table 3, and audibility ratings for each Horn Tone setting is listed in Table 4.
Directional characteristics are as follows:
• 3db @ 35°
• 6db @ 90°
