Customization of Addressable Fire Alarm Systems
Because an addressable fire alarm system consists of several devices all individually identified and connected, advanced configuration allows for greater flexibility. Various protocols can be established for any mix of detection devices, input, or output modules. Addressable fire alarm control panels employ Signaling Line Currents, commonly referred to as SLC loops or just loops, allowing monitoring of just a few devices to several hundred. More complex fire alarm systems could employ multiple Signaling Line Currents.
Addressable systems can be customized with devices in specific areas programmed with different thresholds depending on their location. The addressable control panel recognizes the individual address of each device on the SLC. Typical initiating devices on an addressable system include:
- Heat detectors
- Smoke detectors
- Manual pull stations
- Sprinkler system inputs
- Standard pressure and flow control switches
