The Fire-Lite’s CRF-300-6 six-relay control module provides an intelligent alarm system with six Form-C relays. The first module is addressed from 01 to 154 while the remaining modules are automatically assigned to the next five higher addresses. Provisions are included for disabling a maximum of three unused modules. A single isolated set of dry relay contacts is provided for each module address, which is capable of being wired for either a normally-open or normally closed operation. The module allows the control panel to switch these contacts on command. No supervision is provided for the controlled circuit. Each CRF-300-6 module has panel controlled green LED indicators. The panel can cause the LEDs to blink, latch on, or latch off.
