Installation
Determine if the sensor will be ceiling or wall mounted. Avoid
locating the sensor between double doorways where objects can
be inserted through a crack to gain unauthorized entry.
CAUTION: When handling the sensor, do not touch the
lens window.
To install the sensor, do the following:
1. To open the front cover, insert a small screwdriver into the
bottom of the locking tab and pull upward (Figure 1).
Figure 1. Open the cover
CAUTION: You must be free of static electricity before
handling sensor circuit boards. Touch a grounded,
bare metal surface before touching circuit boards or
wear a grounding strap.
3. Route wiring to the sensor mounting location. If you are
using the wall plate, pull the wires through the cable entry
hole (Figure 3).

4. Insert the mounting screws into the back (wall mount) or top
(ceiling mount) mounting screw holes to fasten the back
housing and wall plate, if used, to the wall or ceiling
(Figure 3).
5. Reinstall the PCB/cradle and secure in place with the PCB
axle screw (Figure 2).
6. Complete wiring connection (See Wiring on page 2).
7. Swing the front cover in place and walk test the sensor for
appropriate coverage and function (see Initial power up on
page 4.
2. Remove the screw holding the circuit board (PCB) cradle
axle to the back housing and carefully remove the circuit
board with cradle from the housing (Figure 2).

Installation Instructions
Wiring
This section provides examples of different wiring options. The
options are all shown in the fail safe mode.
Basic hook-up
Figure 4 shows the basic hook-up for the RCR-REX, a power
supply and a magnetic lock. When the sensor sees motion, power
is removed from the magnetic lock.

CAUTION: For DC powered systems, if the door lock
does not contain a diode across the coil winding,
install a diode across the door lock to prevent
degradation of the lock relay contacts. The diode
should have a current rating greater than the
maximum lock current. Install the diode so that the
cathode end with the bar is connected to the
positive side of the coil.
Spike protection
Many magnetic locks and electric door strikes have built in spike
(diode) protection. If the lock is not spike protected, install a
bridge rectifier, such as a KBL005, between the relay contacts
and the magnetic lock/door strike as shown in Figure 5.

Note: Failure to spike protect the sensor may result in shortening
the life of the relay contacts.
RCR-REX and a keycard reader
Figure 6 shows the wiring normally used when a keycar d reader
is on one side of the door and the RCR-REX is on the other side
of the door. Both swiping a keycard or the detection of motion by
the RCR-REX will remove power from the magnetic lock.

Monitor door contacts (first option)
In the monitor door contacts mode, a person entering the sensor’s
field of view will activate the relay and timer. Door contacts
connected to terminal D will monitor if the door is open or
closed. If the relay timer gets to ten seconds or less (if set for 16
seconds or greater) and the door is still open, the RCR-REX
internal sounder will activate. The sounder will also active if the
door is opened without first activating the sensor or keycard
input. The sounder will remain on until the door is closed or by
someone moving in the field of view (Figure 7).
