The STI steel web stoppers for smoke detectors will stop vandalism, theft, accidental damage and tampering. Manufactured from 9 gauge galvanised steel with a white plastic coating, the STI9604 and STI 9605 will fit smoke alarms that are flush or surface mounted (check the dimensions further down the page) and can be used inside and out.
With the threat of Fire Brigades charging for call-outs to fire alarm activations, STI Stoppers should be fitted in any areas where the risk of abuse or damage is severe such as care homes and warehouse loading bays.
A full range of steel Stoppers to fit detectors, sounders, emergency lights, clocks, motions sensors, CCTV and fluorescent lights is available on request by calling 0800 321 3145.
Suitable for schools, universities, care homes, sports halls and anywhere with a history of smoke detector damage or abuse. Detector not included.
