The Hispec PULSE HSSA/HCO/10 is a 230V mains-powered heat and carbon monoxide alarm with a 10-year rechargeable lithium back-up battery, supplied as a full unit. Combining fixed 60°C heat detection with an electrochemical CO sensor, it suits kitchens and rooms containing fuel-burning appliances. 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.
