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).

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.
Figure 5. Spike protection
Maglock
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).

Monitor door contacts (second option)
If the sensor is activated but the door is not opened, the relay will
drop out after ten seconds. If the sensor is activated and the door
is opened, then closed, the relay will drop out after two seconds.
This prevents unauthorized people from entering (Figure 8).

Many fire codes require a panic button to be part of the installation. The RCR-REX has an X (external) input (see X (input)
external) for a normally open panic button or an internal timer
panic button. When X input is grounded, the door will open. T wo
normally open devices may be connected to the X input
(Figure 9).

NC, C, NO (I/O) monitor relay section
Connect the monitor relay terminals across the normally closed
contacts (NC) of the door switch and across the access control
system. If there is no access control system, connect the normally
closed contacts of the door switch across the monitor relay terminals
R (input) arm
This pin is used to enable and disable the unit with an external
signal. The unit will be disabled when R is grounded for more
than 10 seconds. Thereafter, when R is ungrounded, the unit will
be enabled. Motion detected by the unit up to 10 seconds after R
is grounded and at least 100 milliseconds after R is ungrounded
will start the relay timer.
This pin must be switched with a dry contact or an open collector
transistor referenced to COM (ground).
S (input) sounder
This pin allows external control of the sounder that takes precedence over all other sounder modes. If the unit is powered up
with S ungrounded, then the unit assumes that S is unused.
Whenever S is grounded after power up, the unit assumes that S
is being used to externally activate the sounder. Thereafter , when
S is ungrounded for at least 100 milliseconds, the sounder will
unconditionally turn on and stay on until S is grounded.
This pin must be switched with a dry contact or an open collector
transistor referenced to COM (ground).
X (input) external
This pin can be used by card readers, keypads, remote push
buttons, and key locks to cause the sensor to start a timing cycle.
If X is pulled to ground for at least 500 milliseconds and less than
3 seconds, the lock/monitor relay will unlock the door and the
lock timer will start as if a person walked into the det ecti on area.
If X is grounded for more than 3 seconds, then the relay will stay
in the unlocked state until X is allowed to go high. When X goes
high and if the door is still open, the sounder will produce a
beeping tone and the relay will remain in the unlocked state until
the door closes. When the door closes, the relay will lock the
door and shunt the door switch.
This pin must be switched with a dry contact or an open collector
transistor referenced to COM (ground).
D (input) door
This pin is used to detect the state of the door switch. The door
switch must be connected between pins D and COM (ground). If
the unit is powered up with D ungrounded, the unit assumes that
D is unused. If D is ever grounded after the unit is powered up,
the unit assumes that D is being used to sense door position and
the sounder will beep (if enabled) when the door is left open.
If used, this pin must be switched with a dry contact or an open
collector transistor referenced to COM (ground). See S2-7 (door
monitor mode) on page 4
T and T tamper switch
These two pins connect to the tamper switch, which opens when
the housing cover is opened.
COM (I/O) common or ground
These two pins are connected to ground and serve as the ground
reference when using pins R, S, X, and D.

Floor
To adjust the PIR detection pattern toward or away from the door
opening, do the following:
1. Open the sensor cover (Figure 1 on page 1) and loosen the
PCB axle screw (Figure 11).
Figure 11. PIR pattern adjustment
Initial power up
After mounting and wiring the sensor, apply AC or DC power to
the input power terminals (V+ and V-). Allow at least 2 minutes
following power up for the sensor to stabilize before conducting
any tests.
To walk test the detection pattern, approach the door from all
directions and watch the walk test LED for detection. See
Pattern adjustment if changes are required in the detection area.
Reassemble the sensor and completely walk test again following
any lens adjustment.
To sele ct the appropriate relay time, set the DIP switches as
shown in DIP switch options on page 4.
LED indicator
The LED turns red for the duration of the lock relay time when
motion is detected and flashes twice per second during the 20second warm-up period. The LED turns yellow when the radar
detects motion. The LED turns green when the passive infrared
(PIR) detects motion.
Internal sounder
A continuous tone will sound 15 seconds prior to the end of the
relay timer period. A beeping tone will sound at the end of the
external input (X) signal if the door is open.

Y ou can ad just the radar range from 3 to 15 ft. (0.9 to 4.57 m). To
adjust the range, rotate the range adjustment control ( Figure 13)
to the desired position. The radar range is not affected by the
PCB rotation during PIR range adjustment. The radar range can
be set to just above the floor, to prevent door activation from
objects that have been slipped under the door. After adjusting the
radar range, carefully test to be sure undesired sources of motion
will not be detected.
Fail safe/fail secure modes
The lock relay operates in the fail safe mode (factory default)
when the lock relay state during alarm is the same state as when
the unit is not powered. During the power up period, the relay
will be in the same state as during normal unalarmed operation.
The lock relay operates in the fail secure mode where the lock
relay state during normal unalarmed operation is the same as
when the unit is not powered. During the power up period, the
relay will be in the same state as during the alarm period.
Note: The fail secure mode must be authorized by your local
authority. Listed panic hardware shall be used to allow
emergency exit from the protected area.

Operation
By connecting the lock relay in series with the door lock and the
monitor relay in parallel to the door switch and alarm circuit, the
sensor will allow normal egress and will monitor alarms from the
door being held or forced open. The sensor will monitor the operation of the door switch without affecting the access control system.
When the sensor detects motion, the lock relay contacts open,
unlocking the door, and the monitor relay contacts close,
preventing an alarm from being sent to the access control system
for a fixed time. The time is selected with the DIP switch from 1/
2 to 64 seconds or until reset by the sensor. See DIP switch
options on page 4.
If the sensor does not detect the opening of the door switch within 10
seconds of sensor activation, the lock and monitor relays will return
to their normal condition. If the relay timer is set to 8 seconds or
shorter, the lock relay will change back to the normal condition
when the relay timer times out. After the door switch opens and
closes, the sensor will automatically cancel any remaining relay time
if the door switch remains closed for at least 2 seconds.
The sensor’s sounder will produce a continuous tone to warn of an
open door 15 seconds before the timer closes the lock relay
contacts and opens the monitor relay contacts. Closing the door
will silence the sounder. New movement within the detection area
will restart the timer and reset the sounder. If the door is still open
when the timer ends, the monitor relay contacts will open, which
will cause an alarm signal to be sent to the access control system.

Installation Instructions
Mask installation
The RCR-REX has a mask included that allows you to adjust the
PIR field of view. This may be necessary for some installations
when the unit may be tripped by non-exiting foot traffic or other
erroneous sources that are with the detection area.
To install the mask, do the following:
1. Remove the appropriate segments of the mask to include the
desired area of detection.
2. Open the RCR-REX cover and locate the PIR lens.
3. Slip the mask into the two side brackets that hold the PIR
lens in place (Figure 15). Be careful not to dislodge the lens.
4. Close the cover.
