NOTES: Positive connection for alarm sounder output sits at 6.01VDC (0vdc if Bell supervision jumper is cut, see
below) and provides 14VDC at 1.7A upon activation of alarm.
IMPORTANT:
A battery must be installed, as it supplies the current for the combined auxiliary power, polling loop, and alarm output in
excess of 750mA.
Supervising the Alarm Output
1. Wire polarized fire-indicating devices to the
alarm output as shown in Figure 14.
2. Wire nonpolarized burglary indicating devices
to the alarm output using a polarizing diode
(two 2A diodes supplied), as shown in Figure
15.
3. Program Zone 970 with a response type of 05
(trouble by day/alarm by night).
NOTE: When supervising the bell output (zone
970), only one device can be connected to the
alarm output (terminals 4 and 5) for UL and
Fire installations.
The minimum load on the alarm output
must exceed 5mA at 12V for proper
supervision operation.

If a device such as a siren driver with a
high-resistance trigger input (drawing
UL less than 5mA) is used in a UL Household
Fire installation, the siren driver must
independently supervise siren speaker
wiring.
Using a Siren Driver
1. Mount the siren driver in the panel's cabinet.
2. Wire the siren driver to the control and to the
speaker(s). (See the driver's instructions.)
3. Cut the blue jumper on the upper left-hand
corner of the panel's PC board.
NOTE: Failure to cut the Blue Jumper may
result in a constant trigger for the
driver, subsequently causing the
bell/sounder to constantly sound.
4. Program Zone 970 with no response type (00).
