MX-975 Installation instructions
Addressable door and window cont act
Overview
MX- 975 is a hardwired magnetic door and window
contact device that is compatible with MX control
panels and is addressable in an MX-loop.
The detector has the following features:
Front cover tamper detection
l
Built-in reed switch that opens a circuit when the
l
magnet is moved from its normal position
Alarm and tamper LED indication
l

Installation guidelines
The device enters a two-minute stabilization period
l
when it connects to the power supply for the first
time. Slow LED blinks indicate this event, but only if
the panel is in test mode.
Do not install the device in the following locations:
l
Hazardous locations
l
Areas with a pollution degree higher than
l
pollution degree 2
Circuits above overvoltage category II
l
Mounting guidelines
Mount the detector on the part of the frame that is
l
above the window or door and mount the magnet
below it on the window or door.
Do not mount the magnet more than 6 mm/0.25 in.
l
from the marked side of the detector. To find the
reed switch mark on the detector, see Reed switch
mark in Table 1.
Mounting and wiring the detector
1. To remove the screw cover, insert a flat
screwdriver in the slot and use the screwdriver as
a lever. See Figure 2.
2. To remove the detector cover, remove the screw
with a screwdriver and separate the cover from the
bracket. See Figure 3.
3. To release the PCB, press the PCB support with
your finger or a screwdriver. See Figure 4.
4. Hold the detector bracket in its final position on the
door or window frame. Mark and drill two holes
according to the mounting holes in the bracket.
Fasten the detector bracket to the mounting surface
with two countersunk screws. See Figure 5.
Note: Ensure the reed switch mark on the
detector faces the intended location of the magnet.
5. Fasten the magnet in its final position with double-
sided adhesive tape or screws. See Figure 6.
Note: Before you fix the magnet in its final
position, align it according to the reed switch mark
on the detector. For more information, see Range
coverage directions.
6. Fit the PCB into the PCB support.
7. Wire the detector.
a. Remove the jacket at the end of both cables to
expose the jacketed wires. To expose the
wires, remove the insulation at the end of each
wire. See Figure 7.
b. Feed both cables through the cable openings.
See Figure 8.
c. For each cable, insert one wire in the positive
terminal loop that is marked L+ and the other
wire in the negative terminal loop that is
marked L-. See Figure 9.
d. Close both terminals with a flat-head
screwdriver. See Figure 10.
8. Close the detector and magnet covers. Close the
detector cover with the screw and replace the
screw cover. See Figure 5. Slide the magnet cover
closed. See Figure 6.

Range coverage directions
When mounting the magnet, ensure that the distance
between the magnet and the reed switch mark on the
detector does not exceed the opening and closing
values in the following table.
For more information on the X, Y, and Z directions,
see Figure 11.
