The Signaling Line Circuit Expander (SLCE-127) allows for an additional loop for the PFC-6200 and up to seven additional loops for PFC-6800 fire alarm control panels. Each loop adds 127 addressable sensors or modules in any combination. The SLCE-127 may be configured for Class A or Class B wiring without the need for additional modules. The SLCE-127 communicates with the control panel via the Potter P-Link communication bus. The loop adder is mounted in either the control panel cabinet, the intelligent power supply/P-Link repeater, the PSN-1000E, AE-8 or the AE-14 expander cabinet. Each card is mounted to the exclusive Stacker Bracket for secure and accessible mounting. Potter's Stacker Bracket allows for multiple expansion cards to be placed in a smaller area, multiplying the capabilities of your system.
