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.
Issue
What is the difference between the D133 an D134?
Solution
The D133 has a single relay rated at 2A @ 30 VDC – 0.6A @ 125 VAC.
The D134 has two relays rated at 2A @ 30 VDC – 0.6A @ 125 VAC.
Current draw for the Relay is 40 mA per relay when activated.
Issue
Will an Answering Machine cause the D168A not to answer when accessed locally?
Solution
Some answering machines load down the phone line and cause it to go below 7 VDC. The D168A needs at least 7 VDC to properly process the DTMF tones.

Issue
Can zones 7 and 8 be used as normally open zones, and do they require any supervision?
Solution
Zones 7and 8 are not supervised on the D2112 and D2212 panels and therefore can only be used as normally closed zones, they will not work as normally open zones because no EOL is used. Voltages of 2.4 to 13.9VDC would be an open condition while voltages 0.0 to 1.4VDC would indicate a closed circuit on these points.
