Section 1: Introduction
1.1 Product Specifications
1.2 Dimensions and Mounting Options
NOTICE: This manual shall be left with the owner/user of this equipment.
1.3 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 and CAN/ULC S524 guidelines should be observed.
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.
1.4 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 and
strobes come with 8 field selectable tone and volume combinations and 7 field
selectable candela settings. The devices are intended for indoor applications
and approved for wall-mount and ceiling-mount installations. Strobes and horn
strobes are available in standard and compact versions.
Two-wire horn strobes and strobes are public mode notification appliances
intended to alert occupants of a life safety event. The horn is listed to
ANSI/UL 464/ULC-S525 requirements (public mode) and the strobe is listed to
ANSI/UL 1638/ULC-S526 (public mode).
Two-wire amber ALERT strobes are private mode notification appliances intended
to alert trained personnel to investigate a life safety event.
The 2-wire strobe is listed to ANSI/UL 1638 (Private mode). (Not listed for
Canadian applications)
System Sensor notification appliances are designed to be used in 24VDC 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 2-wire horn strobes and strobes are electrically backward compatible with the previous generation 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 a synchronization module to generate the synchronization protocol.
1.5 Fire Alarm System Considerations
The National Fire Alarm and Signaling Code, NFPA 72, and The National Building
Code of Canada require 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 NFPA 72
(UL applications) or CAN/ULC S524 (ULC applications).
1.6 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).
Section 2: Configurations for Notification Appliances
2.1 Available Tones
System Sensor offers a wide variety of tones for your life safety needs.
Temporal 3 pattern is specified by ANSI and NFPA 72 for standard emergency
evacuation signaling: ½ second on, ½ second off, ½ second on, ½ second off, ½
second on, 1½ off, and repeat.
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
2.2 Available Candela Settings
System Sensor offers a wide range of candela settings for your life safety
needs. To select your candela output, turn the rotary switch on the back of
the product to the desired candela setting. (See Figure 2.) Table 2 shows
available candela options.
The candela setting can be verified from the front of the unit by looking through a small window on the front of the product. (See Figure 19 for window location on device.) All products meet the light output profiles specified in the appropriate UL Standards. (See Figures 3, 4, and 5.)
2.3 Current Draw and Audibility ratings
For the strobe, the current draw for each setting is listed in Table 2. For
the horn strobe, the current draw and audibility settings are listed in
Table 3. Reference binational harmonized standard UL 464/ULC-S525 for minimum
sound level requirements.

Section 3: Installation
3.1 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.
We provide a wire strip guide. See Figure 6 for wiring terminals and strip
guide reference.
3.2 Wiring Diagrams
The 2-wire horn strobe and strobe only require two wires for power and
supervision. (See Figure 7.)
Shorting Spring Feature. These appliances enable system continuity checks of
field wiring on the mounting plate 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 6.)
3.3 Install Back Box
-
Attach back box to wall or ceiling.
– Junction boxes are mounted per industry standard. (See Figures 8, 9 and 12.)
– The surface mount back box may be secured directly to the wall or ceiling. Use of grounding bracket with ground screw is optional. (See Figures 10, 11 and 13.)
– Note for positioning: Wall mount back boxes: Mount with the up arrow pointing up. (See Figure 16.)
– Note for positioning: Ceiling mount back boxes: Ceiling surface mount back box SBBCR/WL is a common back box for ceiling horn strobes, strobes, speakers, and speaker strobes. Use the top (SPK) mounting holes for ceiling speaker and speaker strobe products. Use the bottom (STR) mounting holes for ceiling horn strobe and strobe installation needs.. (See Figure 15.) -

WARNING
THE LIMITATIONS OF HORN/STROBES
The horn and/or strobe will not work without power. The horn/strobe gets its
power from the fire/security panel monitoring the alarm system. If power is
cut off for any reason, the horn/strobe will not provide the desired audio or
visual warning.
The horn may not be heard. 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. 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 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 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 minimized.
