Detection & Alarm Systems

Overview

The safety of a building's occupants depends first on how quickly a fire is detected and announced. Detection & Alarm Systems deliver that function through a network of distributed detectors and a central control panel that ties the system together.

Product Types

The category covers ionization and photoelectric smoke detectors, fixed-temperature and rate-of-rise heat detectors, UV and IR flame detectors, conventional and addressable fire-alarm panels, manual call points (pull stations), and notification appliances (horns, strobes, speakers). The system can also be linked to gas detectors (listed under Gas Detection) and to voice-evacuation systems as designed.

Selection Factors

Detector type is chosen against the expected fire signature (slow smoldering smoke in offices, fast open flame in refineries), the building type (high- or low-rise), ambient temperature, and airflow. The panel is chosen by zone or address count, BMS integration needs, and network coverage requirements.

Difference from Active Suppression

Detection & Alarm does not extinguish the fire; it senses and announces it. That first-layer role is what triggers the response, directs evacuation, and alerts emergency teams.

Standards Note

Systems follow NFPA 72 and EN 54, with UL/FM/CE/SASO certifications. Specifications and certifications vary by product and model.
