1.4 Connecting the Equipment
When connecting the equipment to the termi-
nals provided on the main board and the exten-
sion cards, strip the wires as little as possible
(about 1/4” (6 mm)) to avoid electrical shorts.
Once the wires are connected, run them through
the electrical knockouts provided on the bot-
tom of the AA-400 enclosure and use a cable
holder (2 cable holders are provided for the
battery connections. You can order additional
cable holders from your dealer if needed).
1.4.1 Sensors
The terminals used for sensor inputs are num-
bered Z1, Z2, Z3 & Z4 on the main board.
Connect each sensor to a Z terminal and to its
respective ground terminal (COM). Note that
each ground terminal is used by two zones; for
example, Z1 and Z2 use the same ground.
Make sure each sensor is connected to the
proper ground. False alarms can result if the
ground wires are not properly connected.

1.4.2 Supply Inputs
1.4.2.1 AC Power Connection
The terminals marked 16 VAC on the main
board are used for connecting the transformer.
The transformer provided with the system is a
16.5 VAC/40 VA transformer. It must be
plugged into a 120 VAC / 60 Hz outlet. The F2
fuse (5A fast blow) is connected to this input.
Make sure the power source is unswitched
(i.e. there is no switch on the power outlet).
1.4.2.2 Backup Battery Connection
The terminals marked BATT are used for the
backup battery. The AA-400 system uses a
12 VDC / 7.5 AH sealed lead acid battery. No
other type of battery can be used. The battery
wires run through the tube provided, as shown
on the graph below. Make sure the positive
wire of the battery is connected to the positive
terminal. See Appendix C for normal battery
life spans.
