Issue
Can I mix Heat Detectors and 2 wire smokes with a sounder when using a D132A Smoke Detector Polarity Reversing Module?
Solution
No. When a Heat detector goes into alarm it puts a short on the input zone to indicate the alarm. The D132A uses Aux power from the panel when the polarity reversal takes place and since a heat detector does not reset when polarity is reversed, it would put a direct short on the Aux power of the panel. Consequently everything connected to the same Aux power terminals would not function.

How is point expansion configured, addressed and wired on the D6112 panel?
Solution
Connections:
1.) Install the First Device to the D6112 control by connecting one of the two White leads to terminal 11 (Data- first device). The Black lead will land on terminal 14 (common) and the Red on terminal 15 (+ 12Vdc). This device will be programmed as DEVICE 1.
2.) Install the Second Device to the D6112 control by connecting one of its White leads to the remaining White lead from Device 1. The Black and Red leads of the second device will connect to Common and +12Vdc respectively. This device will be programmed as DEVICE 2.
3.) Each additional device will be installed by connecting its White wire to the previous device remaining white wire until the last device. The remaining White wire on the last device will connect to the D6112 control terminal 13 (Data- last device).
Programming:
1.) Go to the Devices Module part of the D6112 handler and on line 4.1 Device#, select 1 for the first device.
a) On line 2 D1 Model, select the device model code (1=D610/611, 2=D620/D626, 3=D630/D636A, 4=D640) that pertains to the first device.
2.) Continue by selecting 2 on line 4.1 Device# for the second device and on line 4.2 D1 Model, enter that device model code. Continue until all devices are programmed.
3.) Address the points according to the device they are expanded off of. The zone location is comprised of the Device model code and the zone. The zones are identified by letter starting with A for the first zone and counting up alphabetically.
a) Onboard zones 1-8 use a device code of 0 and are addressed as 0A-0H.
b) Zones 9 and up would be addressed 1A, 1B and so on.
Note: It is not required that zones 1-16 be located on any particular device or in any particular order. It is advisable that the system be laid out in a logical order for future reference.
The Alpha keypad offered for the D8112 panel series was the D1252 or D1252A
