Commercial fire alarm and life-safety equipment for office, retail, multifamily, education, healthcare, and industrial deployments. Code-compliant initiating devices, notification appliances, and control panels — sourced direct from the manufacturer or a US channel distributor with full UL listings and AHJ documentation.
Specify a Code-Compliant System
- Control panels — conventional zone panels for small buildings; addressable systems for multi-loop deployments, healthcare, education, and multi-tenant retrofits.
- Initiating devices — photoelectric, ionization, dual-sensor smoke; fixed and rate-of-rise heat; CO; manual pull stations; duct detectors.
- Notification appliances — horn-strobes, speaker-strobes, mini-horns, chimes with synchronized signaling and ADA candela ratings.
- Monitor and control modules — for waterflow, tamper, door-hold, elevator recall, and integration with access-control egress.
- Sprinkler monitoring — waterflow and tamper switches connecting wet/dry/pre-action systems to the FACP per NFPA 72.
