The SK-Monitor is an addressable monitor module for use with Silent Knight
IntelliKnight series fire alarm control panels (FACPs). The SK-Monitor is
intended for use in intelligent, two-wire systems, where individual address of
each module is selected using the built-in rotary switches. The SK-Monitor
supports Class A supervised or Class B supervised wiring to the load device.
Conventional 4-wire smoke detectors can be monitored for alarm and trouble
conditions..
