Three additional tone pulses can be added to each of the four pulse patterns. Two of the tone pulses can guide occupants up or down a stairway, and the third tone pulse identifies areas of refuge.
Smoke Detector Damage Stopper
The STI Smoke Detector Damage Stopper helps prevent vandalism to smoke detectors and is UL listed for specific smoke detectors. This protective device is the simple, low-cost solution for areas where severe vandalism and physical abuse of smoke detectors is causing false fire alarms or high maintenance costs. Its durable polycarbonate design permits itto take tough knocks in stride, and its multiple slots allow smoke to reach the detector.
It is easily installed and may be removed quickly for servicing of the detector. Two UL listed models are available to fit virtually all smoke detectors, the flush mounted STI-8100 and the surface mounted STI-8130 with spacer to accommodate conduit piping (see technical data sheet for specific detector models). Spacer and cover come standard in clear. Also available in almond, black and white.
