Section 1: Introduction
1.1 Product Specifications
1.2 Dimensions and Mounting Options
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, UL50E/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 two-wire horn strobes
and strobes come with 8 field selectable tone and volume combinations and 7
field selectable candela settings. The new LSeries with LED outdoor
notification appliances are designed to be used over a wider range of
temperatures and are suitable for use in wet locations. The devices are
intended for outdoor applications and approved for wall-mount and ceiling-
mount installations.
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 525 requirements (public mode) and the strobe is listed to ANSI/UL 1638/ULC 526 (public mode).
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 or power supply manual for more information.
System Sensor two-wire horn strobes and strobes are electrically backward compatible with the previous generation of notification appliances; new back plates can be connected to existing wires from the FACP. 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 Notification Appliance Circuit (NAC) output configured to System Sensor synchronization protocol, or the use of 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. The total number of strobes on a single NAC must not draw more
current than supported by the FACP.
Wiring terminals or leads corresponding to the rating of the device shall be
provided for connection of conductors of at least the size required by:
a) In Canada only: CSA22.1, Section, Section 32, Fire alarm systems, smoke
alarms, carbon monoxide alarms, and fire pumps.
b) In the United States only: NFPA 70.
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 1.
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 13 for window
location on device.) All products meet the light output profiles specified in
the appropriate UL Standards. (See Figures 3, 4, and 5.)
To calculate sound dispersal per UL464 or ULC 525, refer to Table 4.
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 525 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.
The gasketed back plate ships with wire leads stripped and installed at the
factory; weatherproof wire nuts are required and provided. Wire sizes up to 12
AWG (2.5 mm²) may be used for field wiring.
Make wire connections by stripping about 3/8″ of insulation from the end of
the field wire. Then twist the bare end of the field wire with respective back
plate wire lead and secure the wiring by twisting a weatherproof wire nut into
place.
3.2 Wiring Diagrams
The two-wire horn strobe and strobe only require two wires for power and
supervision. (See Figure 7.) Please consult your FACP manufacturer or power
supply manufacturer for specific wiring configurations and special cases.

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.
