Description Two leds on each detector provide a local 360° visible alarm indication. They die out when the ambient temperature does not reach alarm value. If the temperature reaches the alarm value, then the detector enters to alarm mode and leds light. Operating voltage range: 9 to 28 vdc volts non-polarized maximum alarm current(led on): ≤48ma@24vdc operating temperature range: -10°c to 70°c fix temperature range: 60°c rate of rise alarm: 7.1°c/5s height: 31.78mm installed in base diameter: 99.45mm
