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 devices for life safety notification. Horns come with 8 field selectable tone and volume combinations. L-Series 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 installations.

They 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).

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 outdoor horns 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 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. The total number of strobes on a single NAC must not draw more current than supported by the Fire Alarm Control Panel (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 Current Draw and Audibility ratings

The current draw for each setting is listed in Table 2. Reference binational harmonized standard UL 464/ULC 525 for minimum sound level requirements.
To calculate sound dispersal per UL464 or ULC 525, refer to Table 3.

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 horn requires two wires for power and supervision. (See Figure 3.) Please consult your FACP manufacturer or power supply manufacturer for specific wiring configurations and special cases.

2. Mounting position: Mount with the up arrow pointing up. (See Figure 5.)
3. Select appropriate knockouts and open as needed.
   -­ Threaded knockout holes are provided for the sides of the box for ¾ inch and ½ inch conduit adapter. Knockout holes in the back of the box can be used for ¾ inch and ½ inch rear entry.
   -­ If using the ¾ inch knockout: To remove the ¾ inch knockout, place the blade of a flat-head screwdriver along the outer edge and work your way around the knockout as you strike the screwdriver. (See Figure 6.) NOTE: Use caution not to strike the knockout near the top edge of the surface mount back box.
   -­ V500 and V700 raceway knockouts are also provided. Use V500 for low profile applications and V700 for high profile applications. To remove the knockout, turn pliers up. (See Figure 6.)

3.4 Install Weatherproof Back Plate and Appliance

1. Connect field wiring to wire leads according to terminal designations on weatherproof back plate using the provided weatherproof wire nuts. (See Figures 2 and 3.)
2. Attach weatherproof back plate to the surface mount back box using the four Philips head screws provided. (See Figure 4.)
3. If the product is not to be installed at this point, use the protective dust cover to prevent contamination of the wiring terminals on the mounting plate.
4. To attach product to weatherproof back plate:
   -­ Remove the protective dust cover.
   -­ Align the product housing with the guideposts located on the weatherproof back plate.
   -­ Slide the product into position to engage the terminals on the weatherproof back plate.
   -­ Hold product in place with one hand and secure product by tightening the two mounting screws on the front of the housing. (See Figure 4.)
   -­ Tighten the screws by hand to ensure screws are completely engaged.

CAUTION:
! Factory finish should not be altered: Do not paint!

WARNING
THE LIMITATIONS OF HORNS

The horn will not work without power. The horn get its power from the fire/security panel monitoring the alarm system. If power is cut off for any reason, the notification appliance will not provide the desired audio 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.
