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.
When wireless points are faulted, they display as 'Short' to the panel. When the wireless point tamper switch is faulted it will display as an 'Open' to the panel.
The panel when using a D8125INV and wireless points shows normal/faulted when point transitions from normal to off normal but the control always shows shorted.
Problem may be caused by another point expander connected to the control panel. Remove D8125INV from control panel and determine if points go missing. If points remain active (normal, faulted, etc) the control panel is interfacing with the points through another addressable point expander.

What is the difference between the D133 an D134?
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.
