Fire Alarm Modules
Addressable fire alarm input/output modules for SLC loop expansion. Monitor modules supervise conventional zones and contact inputs; relay modules control HVAC shutdown, door holders, and elevator recall; isolator modules protect SLC loops from short-circuit faults.
Plan Your Deployment
- Select module type: monitor (input), relay (output), control, or isolator based on function
- Confirm SLC protocol compatibility with installed fire alarm panel platform
- Plan isolator module placement per NFPA 72 to limit fault impact on the loop
- Specify relay contact rating for HVAC shutdown, door holder, and elevator recall loads
- Evaluate dual-input monitor modules to reduce SLC address consumption
