GST I-9102(UL) is an intelligent photoelectric smoke detector that can form part of a fire alarm system via connection to a fire alarm control panel. The detector illuminates to indicate its fire alarm status and transmits a fire signal to the control panel.
Using infrared scattering technology, the detector receives very weak infrared light under normal smokeless conditions. If smoke particles enter the chamber, the received light signal will increase by scattering. When smoke density reaches a pre-set level, the detector will sound its alarm. In order to reduce interference and power consumption, the emitting circuit works in pulse mode to prolong the life of IR LED.
GST I-9102(UL) smoke detector features:
- Electronically addressed
- Built-in microprocessor can store 14 history records
- Drift compensation, to suit extensive changing environments
- Standard: UL 268
