The GEMC-BSLC is the hardwired interface between Napco's Burglary Signaling Line Circuit (SLC) Points and compatible control panels. The system comprises a compatible GEMC-Series control panel, at least one GEMC-BSLC and one or more companion GEMCBSLC Points. The Points may be space-protection devices, window/door sensors, relay outputs or other devices that report zone status and supervision information to the GEMC-BSLC. The GEMC-BSLC supports up to 126 SLC Points. A maximum of 2 may be used on a GEMC-Series control panel for a maximum total of 252 SLC Points. The GEMC-BSLC module is mounted inside the control panel housing and connects to the control panel via a plug-in connector. The GEMC-BSLC module continuously monitors each burglary point, updating status as changes in status are detected and conveys this information to the control panel. A total of 4 SLC / RF Receiver modules can be added to the system. Modules 1 and 2 can be either GEMC-BSLC or GEMC-FW-SLC Fire modules (mounted within the control panel enclosure), or GEMC-RECV wireless RF receivers (wired to either the control panel Security bus or control panel Fire bus and mounted throughout the premises). Modules 3 and 4 cannot be GEMC-FW-SLC or GEMC-BSLC modules but can only be GEMC-RECV wireless RF receivers.
