Mircom MPD-65P

The MIR-65 Series incorporate proven sensing technologies, together with advances in materials and electronics technology. Having a wide operating voltage of 9-33VDC, the MIR-65 Series detectors can be integrated into most Fire/Security systems. The MIR-65 Series wide voltage range family consists of photoelectric smoke, ionization smoke, and heat detectors. The photoelectric detector incorporates a pulsing infrared LED located in a chamber within the housing of the detector. The chamber is designed to exclude light from any external source. At an angle to the LED is a photodiode which normally does not register the column of light emitted by the LED. In the event of smoke from a fire entering the chamber, the light pulse from the LED will be refracted into and registered by the photo-diode. If the photo-diode “sees” smoke on the two following pulses (alarm confirmation), the detector changes into the alarm state. A highly visible external clear LED flashes red when the detector is in operational standby and changes to steady red in alarm state. The clear LED allows for easy floor level detector type identification.
