Description

Available with 40-foot and 60-foot protection patterns, QT Series intrusion detectors provide high quality PIR+microwave security at an outstanding value.

Aleph's unique "QT" signal processing evaluates PIR and microwave information while factoring in ambient temperature and light for superior "Quad-Tech"

performance.

Installation

Select an installation height between 7 ft. (2.1 m) and 8.5 ft. (2.6 m). Optimum mounting height is 7.5 ft. (2.3m). Avoid aiming the intrusion detector

towards windows, areas exposed to direct sunlight, and heating/cooling outlets. For best performance, position the detector so its field of view is

unobstructed, and the anticipated path of an intruder will cross the PIR beam pattern.

Pet Immunity: For installations where pet immunity is needed, mounting height should be no lower than 7.5 ft. (2.3m). Animal access above floor level

(furniture, stairs...) may jeopardize the pet immunity feature of the detector.

To ensure Pet Immunity function, do not point detector towards stairways, furniture or room fixtures to which animals have access.

Separate the front and rear covers by first backing out the cover latch screw three to four full turns. 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.

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.

Adjustments

Prior to mounting the detector, configure jumper settings as required (see Fig. 2, below).

& Settings

Pulse Count: When Pulse Count jumper is covering both pins, PC is set at 2: two to three normal steps are required to trigger an alarm. Parking the

PC jumper on one pin (or removing jumper) sets PC to 4: 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.

Microwave Sensitivity: Microwave Sensitivity Adjustment is set to the fully clockwise position at the factory for maximum sensitivity (range).

Microwaves can "see" through walls, so in some cases, such as installation in a small room, it may be desirable to reduce microwave sensitivity.

Turn the Microwave Sensitivity Adjustment (Fig. 2) counter-clockwise to reduce sensitivity. Setting the adjustment to minimum (fully counter-clockwise)

reduces sensitivity to approximately one-third of its maximum value.

SL Front / SL Down: -- Included on Model QT-40SL -- These jumpers independently enable and disable the "Front" and "Down" Security Light (SL)

functions. SL Front controls a single white LED which shines through the front (wide angle) lens. SL Down controls two white LEDs which shine through

the lookdown lens. When enabled, Security Light operates for at least 10 seconds when motion is detected and room light is dim. Continued motion

will cause Security Light to remain on until approximately 10 seconds after motion ceases.
