The WS 26 point addressable smoke detector is designed to give early warning of developing fires. The optical smoke detector responds to increase in smoke density from a smoldering fire and transmits an alarm signal to the FACP.
The WS 26 optical smoke detector has three sensitivity levels calibrated by the degree of light attenuation in smoke. The sensitivity level can be set by means of the P-01 device programmer. When the light attenuation reaches 2/3 of the pre-set threshold the smoke detector transmits a pre-alarm signal to the fire alarm control panel, when the pre-set threshold is exceeded the detector transmits an alarm signal.
The WS 26 smoke detector is available with a standard mounting base or B-IP moisture-proof base (should be ordered separately).
