GENERAL INFORMATION:

The Nos. 650,650-S and 650-12EX provide 17 zones of wide-angle coverage with range of up to 50 feet (152m).

Models 651,651-6 and 65%12EX offer 6 long range zones with reduced angle coverage .up to 100 feet (30.5m).

All models have the following important features:

High precision, computer-designed parabolic optical system.

Dual element pyre-electric sensor.

Precision die-cast optical head for maximum ,RFI protection and accurate optical alignment.

Zone locator for clear visual ind.ication of zone coverage.

Pre-declined zones for fast and easy installation.

Separate pan and tilt control for convenient pattern adjustment to achieve desired coverage or avoid

hazards.

Zone direction not observable when cover is in place.

Wall/corner mounting plate for fast and easy installation.

. Full LED memory/walk-test/night-disable

capability. (LED on Nos. 650,651 will not be active when AC

is absent and thus provides AC supervision.)

The Nos. 650 and 661 must be powered from the No. 1319 plug-in transformer (included) and contain a

rechargeable standby power supply. The Nos. 669-6,661-6,660-12EX require power from a 6V.DC and 12V.DC

source respectively that can provide at least 4 hrs. of standby power. Except as noted herein, these fnstruc-

tions apply equally to the Nos. 669,669=6,66942EX, 661,661-6 and 66142EX.

Normally, the detector will operate at all times regardless of whether the control to which it is connected is

ARMED or DISARMED. Whenever (and while) motion is detected, the unit's LED will light and its relay con-

tacts will transfer. Alternatively, when the detector is connected to a control that can provide a suitable

switched voltage signal to indicate the control's ARMED or DISARMED state, the detector can be

programmed to provide optional modes of LED and relay operation. See OPTIONAL MODES herein.

The Detectors have an additional provision for use of an external LED which can duplicate remotely the indica-

tion of the detector's built-in LED.

PRINCIPLE OF OPERATION:

The optical system divides the area into a series of protective zones. A special sensor measures the level of

'far infrared energy in each zone. When an intruder crosses or enters any zone the resulting change in infrared

energy is detected and an alarm condition will exist.

The sensor does not respond to visible light or changes in the background temperature of the room.

'Because a passive infrared device employs no transmission of any kind, any number of units may be used in

the same area.

Far infrared energy does not penetrate most building materials (even window glass) so the unit responds only

to human movements inside the room.

COVERAGE CONSIDERATIONS AND TYPICAL LAYOUTS:

Nos. 656,65&6,65012u(:

The pattern of protection provided by the 650 series Includes nine main zones which

span an angle of 75"; five intermediate zones aligned in direction with alternate main zones but angled

somewhat downward from the main zones; and three downward zones aligned in the direction of the 2nd, 5th

and 6th main zones, completing the pattern of protection. See Diagrams 1 and 3.

The entire pattern may be panned left or right up to 20'.

The-optical system has been designed to give proper coverage based upon a typical mounting height of 7'6"

(2.3m). However, the unit may be mounted at any height between 7' (2.lm) and 9' (27m) to achieve a proper 50

(15.2m) pattern.
