No tools are required for installation other than pulsed infrared source operating with a gated, high-speed, the hex key used to tighten the tamper screw.Each detector photodiode infrared sensor.The symmetry of the optical head requires a D7050-B6 detector base. chamber allows 360° uniform smoke entry, but minimizes Chamber Check Self-diagnostics external light entry. The detector meets NFPA guidelines for sensitivity testing, Use both of these smoke detectors for detection circuits because you can visually inspect the detector and check the installed in areas where personnel are present.The flash rate of the LED.If the calibration is out of factory-listed D7050TH has an added fixed-temperature sensor.This range,the LED on the detector double flashes once every 3 expands the detector application to confined areas where sec to 8 sec.

LED Operation When the detector is operating normally, the LED flashes once every 3 sec to 8 sec. In alarm, the detector flashes at least once per second. Magnetic Test Feature Test the detector's operation by placing the SMK-TM Test Magnet next to the detector's LED for three consecutive flashes.This causes the detector to send an alarm. www.boschsecurity.com
