These smoke detectors are for use with Fireboy-Xintex FR Series Fire detection systems.
Photoelectric smoke alarms are ideal for detecting slower-burning, smoldering fires that produce a lot of smoke — and evidence indicates that the majority of all fire-related deaths are actually due to smoke inhalation.
Additionally, photoelectric smoke detectors typically respond faster and with greater reliability than ionization detectors. They are also less likely than ionization detectors to trigger a false alarm from kitchen and bathroom steam.
Photoelectric detectors trigger when smoke particles enter the detector and cause an internal beam of light to be deflected (bounce off the smoke particulartes) toward a light detecting sensor, triggering an alarm.
