319.5 Crystal Maxlife Door/Window Sensor

Installation Instructions

Only one door/window input can be used at any given time. For 
example, if the external contact is used, internal reed switches 
(Reed A and Reed B in Figure 3 on page 1) cannot be used.

Note:  Power down the device before positioning the input selection.

See Figure 4 and position the input selection jumper to select:

Reed B.  Left two pins covered (default).
Reed A.  Right two pins covered.
External contact.  Jumper removed. 

Before mounting the sensor, verify the sensor mounting location 
provides good RF panel communication.
To verify:
1.

Put the panel/receiver into sensor test mode.

2.

Take the sensor to the mounting location.

3.

Hold the magnet next to the alignment mark on the the 
sensor (Figure 5) and then pull the magnet away from the 
sensor.

4.

Listen for siren beeps to determine appropriate response 
(refer to the specific panel/receiver documentation).

5.

Exit sensor test mode.

To mount the sensor:
1.

Remove the sensor battery.

2.

Remove the circuit board from the sensor base by pulling 

back on the plastic tab.

3.

Mount the sensor base using the screws provided 

(Figure 6).

4.

Replace the circuit board.

5.

Remove the magnet from its base.

6.

Line up the magnet alignment mark with the sensor align-

ment mark, depending on the internal reed switch being 
used (Figure 5).

7.

Mount the magnet base with the #6 x 0.625 in. PPH screws 
no more than 3/8 in. (0.95 cm) away from the sensor base 

(Figure 7). Replace the magnet cover.

8.

Insert the sensor battery observing correct polarity (Figure 3 
on page 1).

9.

Attach the sensor cover to the base.
