13-4 Alarm Output Devices Installation Manual
Connecting the Central Alarm
You will need 22-gauge, 2-conductor plenum-
rate cable for installation.
The Alarm Output device from each Controller
can connect to any of the 8 alarm inputs at the
“Zone Alarm Terminal Strip” on the Central
Alarm.
In addition, a common ground from each
Controller connected to the Central Alarm is
required.
To connect the Central Alarm, refer to Figure
13.4 and use the following instructions:
Figure 13.4 The Central Alarm
1. Using the BLACK wire, connect one of
the ground terminals on the Zone Alarm
Terminal Strip of the Central Alarm unit
to P9-pin6 (Ground) terminal of the
Controller you are connecting.

2. Using the RED wire, connect one of the
terminals on the Zone Alarm Terminal
Strip in the Central Alarm unit (
with a
diode in-between the RED wire and Central
Alarm; Figure 13.5
) to P9-pin3 (Alarm
Out) of the Controller you are
connecting.

The Speakers (Figure 13.6) provided by Accutech
(Sentrol/Moose MPI Series) are 8-ohm speakers.
The tone board works with as little as 4 ohms.
NOTE: Sometimes a different tone is used for
each zone to distinguish one zone from another.
If you wish to use the same sound for one of
more zones, you will need to put a 1W diode
(1N400X ) in parallel with each signal that will
share a tone, and have their common cathodes
connect to the same terminal on the Zone Alarm
Terminal Strip.
When wiring the Speakers to the Central Alarm
unit, it is best to find a combination of series and
parallel connections that keep the total load of
the Speakers as close to 8 ohms as possible. You
may wish to consult with an Accutech technical
support person to verify your load.
