Passive infrared sensor PA-450PIA

High reliable detection performance with a simple and compact design The coverage pattern can be adjusted by moving the inner PCB to allow different mounting heights. Zone focused directly below sensor eliminates typical "dead" area just under the unit. According to the environment at the site, sensitivity can be adjusted by 4 steps : 60%, 80%, 100% or 120%. Pulse count can be adjusted to 1, 2, 3, or 4 times. ※Do not use count 3,4 for PA-460EA The alarm LED blinks for 3 min and remains lit for 47min, and then resets automatically. The alarm LED lights when the sensor detects for 5 min after warming up. Detection system - Passive infrared Coverage - Wide Angle 12m(40' ) max.
