ISD smoke detector is a wireless, battery-powered device design to be used with a Videofied security system. The detector is embedded with a smoke detection module, a buzzer and a radio module. Install the detector in the middle of the zone to protect. Installing the detector too close from a combustion source (kitchen with few windows or poorly ventilated, garage, furnace, hot water heaters, space heaters, etc.) or close to a humidity source (bathroom) can trigger false alarms. If the sitehas several floorsn install at least a smoke detector on every floor. The detector is powered by a 3V Duracell CR123A Lithium battery for a two year battery life (on average). When the ISD smoke detector triggers, it generates a sound alarm and the information Smoke Detection is sent to the monitoring station through the alarm panel.
