DSC T-REX – Installation Manual – English – PIR Request-To-Exit Detector

Installation to the illustration below for the recom- mounting positions. When selecting appropriate mounting position, keep in the potential for air drafts or objects to be through gaps around the door and into detection area. cable entry opening into the T.Rex is on right back side, near the cover retaining There is a recess in the back of the to allow wires to be routed from any point the T.Rex to the cable entry opening. remove the cover, then remove the de- barrel from the back casing by rotating barrel upward. Route the wiring into the back casing. mount the back casing to the wall. Install the detector into the back casing and connect the wiring. This is a time to modify the jumper settings if necessary; the settings are explained on the next page. Make sure the barrel is free to rotate, to permit final adjustment. the cover, left end first (the end with 2 hooks). Settings are a total of 7 jumpers on the left side of the circuit By default, all jumpers are ON. Jumper jumper selects whether or not the LED changes color the main relay is activated. By default, the LED is ena- to follow the relay activation. Jumper jumper selects between normal and high sensitivity. set to high sensitivity (the default), the LED is normally and turns green when the main relay is activated. This is recommended for exit detector use. normal sensitivity is selected, the LED is normally and turns red when the relay is activated (selecting sensitivity allows the T.Rex to be used in unsteady Jumper jumper determines the relay operation: in Latch mode default), the relay activates for the duration of the main timer setting whenever someone is detected. Follow mode (jumper removed), the relay stays on only as as there is activity in the detection zone, but up to a time equal to the main relay timer setting.
