Profile: Elecheck (EST) Limited offers services such as portable appliance testing, fixed installation testing, fire alarm inspection, carbon monoxide detection, smoke detection, emergency lighting inspection, irPIR Safety InspectionT, lightning protection and water risk assessments. We install and maintain a variety of smoke alarms. Smoke alarms incorporating either an ionization or an optical sensor are available in mains only, mains with alkaline battery back-up, or mains with re-chargeable lithium back-up formats. Strobe light and vibrating pad alarms are available for the hard of hearing or the deaf. The pad is placed under a mattress or pillow and when smoke is detected, the alarm will sound & set off the light and pad. Radio linked alarms can also be installed, so that when one detects a fire, they all sound.
