PIR Intrusion Detector

1.0Specifications

•Input Power: Connects directly to the Multiplex Bus of the Control Panel and optionally to an auxiliary 12 VDC source.

•Current Draw:

2-Wire:

LED Off:< 350 µA draw on Mux Bus.

In Alarm; LED On: 2 mA draw on Mux Bus.

4-Wire:

LED Off:< 350 µA draw on Mux Bus.; 0 mA draw on Aux. power.

2.0Control Panel Programming

Refer to the multiplex programming section of your Control Panel Reference Guide for information on programming multiplex zones for this device.

In Alarm; LED On: < 350 µA draw on Mux Bus; 3 mA draw on Aux. power.

• Standby Power:	There is no internal standby battery. Connect
	to DC power sources capable of supplying
	standby power if primary power fails. For each
	hour of standby time needed, 350 µAh are
	required. For UL Listed Requirements, four
	hours (1400 µAh) minimum are required.
• Coverage:	360° by 60 ft. (18.3 m) diameter coverage
	when mounted on 8 to 18 ft. (2.4 to 5.5 m)
	high ceilings. Pattern consists of 64 zones

		grouped into 16 barriers, with one additional
		zone looking straight down from the unit
		(sabotage). Each barrier is 30 ft. (9.2 m) long
		and 4.4 ft. (1.3 m) wide at 30 ft. (9.2 m).
		Choice of two optical modules depending
		on ceiling height. For UL Listed
		Requirements, the coverage is 360° by 54 ft.
		(16.5 m) when mounted 10 to 13 ft. (3.1 m to
		4.0 m) using the AR8-13 array and when
		mounted from 15 to 18 ft. (4.6 m to 5.5 m)
		using the AR13-18 array.
•	Sensitivity:	Selectable for Standard, Intermediate or High.
•	Tamper:	A tamper condition is signaled through the
		Multiplex Bus and displays at the system
		keypads.
• Temperature:		The storage and operating temperature
		range is -20°F to +120°F (-29°C to +49°C).
		For UL Listed Requirements, the
		temperature range is +32°F to +120°F (0°C
		to 49°C).
•	Control Panel

Requirements: DS7400, DS7400X, or DS7400Xi Control Panel with a DS7430 or DS7436 Multiplex Expansion Module. DS7400 and DS7400X require ROM version 1.07 or greater. The 9000 Series Control/Communicators with D8125MUX Module installed.

•Patents:This device is covered under one or more of the following U.S. patents: #4,764,755, #5,268,668, and #5,302,941.

The mounting surface should be solid and vibration free (i.e., drop tiles should be secured if the area above the

IMPORTANT tiles is used as an air return for HVAC systems).

•Select a location that is most likely to intercept an intruder moving across the coverage pattern. The recommended mounting height range is 8 to 18 ft. (2.4 to 5.5 m).

•Remove the cover by turning counterclockwise.

•Remove the base from the enclosure by pressing the two enclosure release tabs inward while lifting the enclosure away from the base.

Hint: Slightly rock the enclosure side-to-side during removal, to overcome the friction caused by base-to-enclosure terminal pins.

•Route wiring as necessary to the rear of the base and through the center hole.

Be sure all wiring is unpowered (de-energized) before routing.

•Securely attach the base. Depending on local regulations, the base may be directly surface mounted using anchors, mollies or wing-nuts, or may be mounted to standard four-inch octagonal and square electrical boxes.

NOTE: The MX938i base will not completely cover a four-inch square box. Where aesthetics are important, a four-inch octagonal box is recommended.
