DynaLock 6420 Passive Infrared Request-To-Exit Sensor

The DynaLock Series 6420 passive infrared Request-To-Exit sensor detects the differential between a human body and the floor. Featuring a dual-pyroelectric design, for increased stabilty against external light, the 6420's pyramid-shaped detection filed is positionable from straightdown verticle to 35" in front of the door and special circuitry provodes high-immunity to RFI and other electrical noise. Two, built-in SPDT dry relay output contacts are rated for 1 Amp at the rate 30VDC and an adjustable timer may be set for 0.25 to 60 seconds of relay hold time. Additionally, the output relay's mode may be set for fail-safe or fail-secure operation and an on-board LED indicator may be set to illuminate during relay hold time. The 6420 accepts 12 to 24 VAC/VDC input power and is designed for wall, ceiling or door frame mounting. It is ideally suited for access control, lock release, alarm shunting and automatic door operation.
