Can I mix Heat Detectors and 2 wire smokes with a sounder when using a D132A Smoke Detector Polarity Reversing Module?
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.
