It goes without saying that every home or business requires a smoke alarm. The DSC 2-Wire Photoelectric Smoke Detector w/Heat is a sophisticated smoke detector that won't let you down. And since the unit is sensitive to both heat and smoke, it will eliminate the often expensive need to purchase additional equipment.
The smoke detector has a nominal fixed alarm sensitivity and it will go into alarm when the signal level exceeds the 'alarm' threshold and send the alarm signal to the control panel. During an alarm the LED will flash once per second and the siren will sound the evacuation temporal pattern (UL) or continuous beeps (ULC).
The detector automatically compensates for long-term environmentally induced changes to maintain a constant smoke sensitivity. When the drift compensation has reached its high or low limit adjustment, the detector will go into the trouble state.
The heat detector will go into alarm when the hear signal level exceeds the heat alarm threshold of (135deg.F/57deg.C); and send the alarm signal to the control panel. The detector will also go into heat alarm if there is a rapid increase in the temperature over a short period of time. During an alarm the LED will flash once per second and the siren will sound the evacuation temporal pattern (UL) or continuous beeps (ULC).
How It Works
Approximately every 7 to 8 seconds the unit tests for a smoke or heat alarm condition. During this sequence the unit also performs self diagnostic, and checks for faults. During normal operation the LED will flash every 50 seconds and the siren will not sound.
Remote Alarm - Interconnection
Multiple detectors (with sirens) can be connected using a polarity reversal module. When a fire alarm occurs, the panel will signal the module to reverse the polarity of the 2-wire loop. This will activate the sirens of all units connected on the loop.
