SOUNDER OUTPUTS
The Horn Output provides 12VDC to power bells, piezo sirens, self-contained sirens, and siren drivers (do not connect
speakers to the Horn Output). Sounders can draw up to 1 amp MAXIMUM, split between the Interior and Exterior
Horn Outputs - (See Specifications for UL Ratings). Use a relay connected to an auxiliary power supply if higher
current draw is required.
INTERIOR SOUNDER HOOKUP
1. Locate the interior sounder in a central location. The sounder is very loud. Do not install it in a room where small
children or animals could be trapped if the alarm is activated.
2. The Interior Horn Output monitors the wiring to bells and sirens. When enabled, it will report trouble and make a
digital dial out when an open, short, or other wiring problem is detected in the supervised bell circuit. When
violated, the following trouble is displayed on the console, "FIRE TAMPER TRBL NOW".
3. For UL Listed residential fire alarm applications, the UL Listed Wheelock Model MT-12/24-R Multitone Signal or
equivalent must be used, and the "SUPERVISE INT SNDR" feature must be set to "ON".
4. Refer to FIGURE 8 (SOUNDER CONNECTION) for connections.
EXTERIOR SOUNDER HOOKUP
1. If used, wire tamper switches to a tamper zone with a 1000-ohm end-of-line resistor.
2. The Exterior Horn Output monitors the wiring to bells and sirens. When enabled, it will report trouble and make a
digital dial out when an open, short, or other wiring problem is detected in the supervised bell circuit. When
violated, the following trouble is displayed on the console, "FIRE TAMPER TRBL NOW".
3. To enable supervision of the Exterior Horn Output, the "SUPERVISE EXT SNDR" feature must be set to "ON".
5. Refer to FIGURE 8 (SOUNDER CONNECTION) for connections.
