REX Sensor - Part Number: REXM

The pdk Motion Request to Exit (REX) device is a perfect way to provide free egress by cutting power to a maglock. The REX sensor is specifically designed for indoor applications and features a passive infrared sensor with qualified motion analysis. The sensitivity of the REX sensor is easily adjusted for long- or short-range applications and features an adjustable time delay. Because of its sleek design, the REX sensor is easily mounted to any frame, header wall, or ceiling. The REX sensor is intended for indoor use only and is available in a white or brown enclosure.

REX devices are used in conjunction with access control systems to ensure that tenants are able to freely and safely exit an area. Options such as exit buttons, hands-free infrared, or touch-sensitive devices make a REX device an ideal choice for releasing maglocks or door strikes.

Mounting Instructions

Select a mounting location over the center of the door or doors to be covered. The target must walk directly toward the detector. Mount the detector on the ceiling, wall, or door frame. The mounting height range is from 7 ft. to 15 ft.

Remove the front cover from the detector.

Route the wiring as necessary through the wiring entrance. For surface wiring, use the breakout wiring entrance on the front cover (at the same end as the wire entrance).

Loosely mount the back cover to the mounting surface using the supplied mounting screws.

Aim the detector for the desired coverage.

Mount the front cover on the detector. Choose between long-range and short-range detection patterns by adjusting the detector’s angle.

Long & Short Range Adjustment

The REX Sensor can be set to detect individuals at either a long range (several steps from the door) or at a short range (immediately in front of the door). If the building includes a lengthy approach to the exit doorway and there is no other foot traffic in the area, choose the long-range setting.

Setup and Testing

1. After mounting, apply power to the unit.

2. Wait at least 3 minutes for the detector to settle.

3. Test the unit by walking directly through the coverage area toward the door.

4. Aim the detector up or down if necessary to obtain the proper coverage.

5. Angle adjustment is from -20 degrees to 90 degrees.

6. Check that the relay latch time is sufficient. Adjust if necessary.

7. After confirming proper operation, replace the cover and perform a walk test one more time to ensure the coverage has not changed.

Detection Pattern

The figures below show the standard patterns for a wall-mounted unit. Rotate the lens to adjust the detect range (long range and short range).

Wiring

V+ - Power Connection (12 - 24 VDC/VAC)
V- - Power Negative (Ground)
NO - Normally Open
NC - Normally Closed
C - Common

CAUTION: Incorrect wiring will result in product damage.

Wiring a REX with a Mag Lock

Connect a wire from the Controller Port positive (+) terminal to the Mag Lock positive (+) terminal
Connect a wire from the Mag Lock negative (-) terminal to the REX normally closed (NC) terminal
Connect a wire from the Controller Relay Port normally closed (NC) terminal to the Rex common (C) terminal
Connect a wire from the Controller Input block REX (B) terminal to the REX normally open (NO) terminal

DIP Switch Settings

DIP Switches 1, 2, 3 - Latch Time

DIP switches 1, 2, and 3 set the relay latch time. Latch time is the amount of time the relay remains active after the REX first detects motion. Latch time is adjustable from 0.5 sec to 64 seconds.

Table 1: Latch Time DIP Switch Settings

Time (seconds)	Switch 1	Switch 2	Switch 3
0.5 (Default)	OFF	OFF	OFF
1	ON	OFF	OFF
2	OFF	ON	OFF
4	ON	ON	OFF
8	OFF	OFF	ON
16	ON	OFF	ON
32	OFF	ON	ON
64	ON	ON	ON

DIP Switch 4 - LED

Table 2: DIP Switch Settings to enable/disable the LED

Switch 4	Function
OFF	Disabled
ON	Enabled (Default)

When LED is enabled, it will flash on and off when first powered up. Once the flashing LED stops, the REX is ready to be used.

DIP Switch 5 - Relay Mode

Table 3: DIP Switch Settings for Relay Mode

Switch 5	Function
OFF	Fail Secure
ON	Fail-Safe (Default)

A fail-secure locking device remains locked when power is lost.

A fail-safe locking device unlocks when power is lost.

DIP Switch 6 - Resettable / Non-resettable

Table 4: Resettable / Non-resettable DIP Switch Settings

Switch 6	Function
OFF	Non-resettable
ON	Resettable (Default)

Resettable: The relay activates when the detector first sees motion. Any additional motion restarts the latch timer so the relay deactivates only when the detector no longer sees motion and the latch time has expired. Hint: This setting works best when bypassing a 24-hour contact.
Non-resettable: The relay activates when the detector first sees motion. It deactivates when the latch time ends, even if motion is still present. Hint: This setting works best when used with an access control system.

Troubleshooting and Maintenance

Trouble	Cause	Remedy
REX does not power up	No or low input power. Input power polarity reversed.	Apply proper input voltageCorrect wiring polarity.
Alarm LED does not light	LED jumper is set to LED OFFIncorrect sensor mounting height.	Set LED jumper to LED ENABLE Increase/decrease the mounting height.
LED indicates light, no signal output	Incorrect wiring at output terminal lighting damage.	Correct the wiring faultReplace the sensor.
The unit continues to operate after the input power has been disconnected.	The wire to the “V-” (Ground) power input was disconnected. The “V+” is still connected.	Disconnect wire from the “V+” power input.
