Quad-Tech Intrusion Detectors
Models QT-40B / QT-40BSL
40ft (12m) L x 56ft (17m) W
For best performance, position the intrusion detector so its field of view is free of obstructions, and the anticipated path of an intruder will cross the PIR
“fingers” of the pattern. The detector may be installed at any height from 7 ft. (2.1 m) to 8.5 ft. (2.6 m). Optimum mounting height is 7.5 ft. (2.3m). Avoid
aiming the detector at windows and/or areas exposed to direct sunlight; do not mount the unit so it is looking directly at heating or cooling sources.
Wire the detector to the control panel using 18 to 22 AWG conductor, standard non-shielded cable. Avoid running alarm wiring parallel to AC wiring.
Wiring knockouts and wire channel are provided in the rear cover for unobtrusive wiring. Terminal block configuration is shown in Fig. 3, below.
Prior to mounting the detector, configure jumper settings as required (see Fig. 2, below).
Pulse Count:
When Pulse Count jumper is covering both pins, PC is set at 1: two to three normal steps are required to trigger an alarm. Parking the
PC jumper on one pin (or removing jumper) sets PC to 2: four to five steps will trigger an alarm.
LED Enable:
When Jumper is covering both pins, the Alarm LED is enabled. The Alarm LED glows through the lookdown lens when an alarm is
signaled at the Alarm Output terminals. LED brightness automatically increases when light level in detection area is high. As room light dims so does
the LED brightness. Parking the jumper on one pin (or removing jumper) disables the Alarm LED but has no effect on the alarm output.

Separate the front and rear covers by first removing the cover latch screw. Then use a small screwdriver or similar tool to release the cover latch. To remove
the PCB, push the PCB latch away from the board while grasping a terminal block and pulling the PCB out of the cover. Do not pull on the microwave
module. Refer to Figures 1 and 2, below.
The SL model includes all of the standard QT-40B features and adds the Security Light feature.
