Advance Protocol Intelligent Monitor Module

The MIX-M502MAPA Interface Module is intended for use in intelligent, two-wire systems, where the individual address of each
module is selected using the built-in rotary decade switches. This
module allows intelligent panels to interface and monitor two-wire
conventional smoke detectors. It transmits the status (normal,
open, or alarm) of one full zone of conventional detectors back
to the control panel. All two-wire detectors being monitored must
be ULC compatible with this module. The MIX-M502MAPA has a
panel controlled LED indicator.
