How many 2 wire smokes will the D7112 support on zone 1?
Manufacturer & Models, and the number of smokes
Radionics D262 with the D260 base = 20 smokes
DS200 with the MB200-2w base = 10 smokes
System Sensor 1400 = 10 smokes
System Sensor 2400 = 10 smokes
System Sensor 2400TH = 10 smokes
System Sensor 1451 with the B401 base = 10 smokes
System Sensor 1451 DH with the DH400 base = 10 smokes
System Sensor 2451 with the B401,B401B or DH400 = 10 smokes
System Sensor 2451TH with the B401,B401B or DH400 = 10 smokes
System Sensor 2300T = 10 smokes
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.
