The ceiling-mounted passive infrared detector is designed for use with modern residential and commercial security systems. This device is fitted with pulse-counting circuitry and employs a pyroelectric sensor equipped with 2 elements that provide substantial immunity against false alarms due to environmental factors.
Detection pattern: 360° conical pattern, dia 35ft when installed at a height of 12ft
Quiescent current: 15mA typical at DC 12V
Relay output: Normally closed (fail-safe) dry relay contact, 18ohm resistor is connected in series with the contact
Alarm activation delay: 2 - 3 seconds
Tamper output: normally closed contact
LED: walk-test enabled or disabled with internal link
Pulse counter: single- or double-pulse detection through alternating signal polarity
