FAQs
What are the functions and typical applications of the various Fire SLC Signaling Line Circuit modules?
Zone Modules
- FWC-FSLC-EZM2 Dual Input Monitor Module - This module is typically used for connecting non-powered conventional alarm points to the system via the SLC. This module can have two different zones mapped to it using the same SLC address (point 1 and point 2). Typical applications include monitoring water-flow, high and low pressure, gate valve switches on Fire sprinkler systems, conventional heat detector / pull station loops, smoke beams, suppression system / panels or any other non-powered alarm points required to be monitored by the Fire system.
- FWC-FSLC-EZM1 Fast Response Contact Module - Same as the FWC-FSLC-EZM2 above but only one zone can be mapped to the module. The FWC-FSLC-EZM1 is small and can be mounted behind other devices (e.g. a conventional pull station).
- FWC-FSLC-CZM Conventional Zone Module - This module is used for connecting 2-wire smoke detectors into the control panel via the SLC loop; often used when upgrading the control panel in a large conventional system with more than eight 2-wire smoke loops. Module requires power to be connected to the module along with the SLC loop.
Output Modules
- FWC-FSLC-RM2 Dual Relay Output Module - This module uses two SLC addresses, one for each relay. Relays can be programmed to trip for the same or different alarms. Typical applications include HVAC shutdown, elevator recall / shunt, closing door holders, fire dampers or anything that needs to be activated or deactivated during an alarm condition.
- FWC-FSLC-SOM1 Supervised Output Module - Typically used for connection to a remote NAC panel, bell or any output that requires end-of-line supervision. Requires an external power connection.
Other Modules
- FWC-FSLC-ISO Short Circuit Isolator Module - Checks the line for short circuit at power up. Used to isolate and protect sections of the fire SLC loop, to prevent entire loop failure. Module does not retrieve addresses nor is programmed into the system, but is wired between any two devices on the SLC loop. Note: FWC-FSLC-ISO modules are required by NFPA for Style 7 wiring.
