The Hispec PULSE HSSA/OH/10 is a 230V mains-powered smoke and heat multi-sensor alarm with a 10-year rechargeable lithium back-up battery, supplied as a full unit. Combining an optical smoke sensor with fixed 60°C heat detection, it gives two ways of detecting a fire in one alarm. It can be hard-wire interconnected with up to 20 alarms, and can be made wireless by adding the plug-in Hispec RF PRO module (HSSA/MOD/RF-PRO). Its sensor is tested throughout manufacture and calibrated for fewer false activations.
