4.3: Two-wire wiring D132A modules to a B Series panel for 12 V power supplied by an external power supply
1 Detector loop (2‑wire)
9 Connection from D125B switch power
to control panel’s A output relay (NC).
Set the Output A jumper for AUX PWR.
2 EOL resistor
10 Connection for D125B Zone B to an
on-board point on the control panel
3 D132A module
11 Connection for D125B Zone A to an
on‑board point on the control panel
4 Connections for one D132A fire point
to D125B A loop
12 Connection from D125B Common
(either 4 or 5) to the control panel’s
common for the on‑board points
connected
5 Connections for the other D132A fire
point to D125B B loop
13 External power supply (12
VDC)
6 Connection for AUX PWR - from D132A
modules to B-series panel COM
14 Earth Ground
7 Connection for AUX PWR + from
D132A modules to B-series panel AUX
15 B Series control panel
8 Connection from reverse trigger on
D132A modules to control panel B or C
output. Pull to GND to activate
16 D125B module
Notice!
The illustration shows the D132A modules wired for both detector loops triggered by the
same output. For loops triggered by separate outputs, connect one D132A module reverse
trigger to B output and the other D132A reverse trigger to C output.
