Answer:
The cable connects to Notifier or System Sensor addressable fire alarm panels via an addressable intelligent monitor module, or directly to conventional fire alarm control panels, requiring an end-of-line (EOL) box or resistor for continuous line supervision.
The SS-LD-68-155 acts as a normally-open dry contact initiating circuit and is fully compatible with both addressable and conventional fire alarm architectures:
- Addressable Systems: Connects to Notifier and System Sensor addressable fire alarm control panels via an intelligent monitor module. The module translates the short-circuit alarm state of the cable into a discrete addressable point on the Signaling Line Circuit (SLC).
- Conventional Systems: Connects directly to initiating device circuits (IDC) of standard conventional fire alarm control panels supporting dry contact inputs.
- Supervisory Hardware: Requires an End-of-Line (EOL) box or termination resistor at the far end of the detection circuit. This enables the panel or monitor module to maintain continuous open-circuit and short-circuit fault supervision along the entire cable length.
