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, 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).

System Design
Introduction
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 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.
