Changing the Infrared Cell
WARNING
COMPONENTS MAY BE HOT. TURN OFF DETECTOR AND
DISCONNECT POWER ADAPTER CORD BEFORE REMOVING
THE INFRARED CELL DOOR.
The D-TEK Select’s infrared cell (IR cell) is located in the body of the detector.
The IR cell is a complete assembly consisting of a metal tube, connectors and
electronic components. The IR cell is not designed to be taken apart. Doing so will
destroy the cell. This specialized IR cell will operate for about 800 hours.
The D-TEK Select will flash all the yellow leak indicators when the IR cell has
reached the end of its useful life. To replace the IR cell:
1. Locate on the top cover (at the rear of the detector) the latch for the IR cell door.
2. Using a small screwdriver, pull the latch forward and remove the door.
3. Grasp the IR cell according to the directions printed on its label.
Pull it straight out so both ends are released at the same time.
4. Remove the replacement IR cell from the protective package.
5. Carefully align the male leads and air tubes on the IR cell with the connectors
mounted on the circuit board. Insert the leads into the sockets and push the IR
cell straight down.
NOTE: Ensure the lead connectors on the IR cell ends are not bent and the cell
is seated tightly.
Removing/Replacing the Power Stick
The D-TEK Select uses a pre-assembled power stick.
Remove the battery compartment door on the back of the D-TEK Select by
pressing on both release buttons on the grip and pulling the door straight out. The
power stick is connected to the PCB board via a miniature electrical connector.
Disengage the connector and slide the power stick out of the D-TEK Select.
Slide the new stick into the D-TEK Select and push the miniature connector on the
power stick into the mating half on the PCB board. Do not bend the PCB board’s
connector away from the board. Once the power stick is in place, close the battery
compartment by aligning the two tabs and sliding the door straight in until it
latches. Ensure the wire leads on the power stick are not pinched in the door.
Allow 10 hours to fully charge the new power stick.
