The AMP-702 is an addressable (AML) normally open, EOL resistor supervised input module that connects to the 2-wire addressable polling loop of the PC4020 or PC5100 module. The 2-wire loop provides both power and communication. Addressable burglary and fire detectors cannot be connected to the same addressable loop unless the burglary detectors are isolated from the fire detectors using an AML-770 or AMX-400 module.
