If using the D220A on the D2112 do I have the Exit Feature?
No, the D2112 does not have the Exit Feature. It uses the "Step Out Feature". The Exit Feature does appear on page 23 of the Users Guide, but that is because this Keypad can also be used on other 2000 Series Panels which have the Exit Feature.
The D5200 needs to match a Data Lock code in the panel to access programming. Changing the panel Data Lock Code from the default of 12345 will prevent access.
Remote Programming Software:
RPS also needs to match the Data Lock code in the panel to access programming. Changing the panel Data Lock Code from the default of 12345 will prevent access.
RPS also needs to match the RPS Passcode (or RAM Passcode in legacy types) in order to allow access programming. Changing the default from 999999 will block RPS access.
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.
