Wiring a Maglock with a REX Device

Installing a REX & Maglock to a Door Controller

The following illustration identifies the placement of Single io board terminal blocks and their basic functions. 

The following illustration identifies the location of Cloud Node board connections. 

When installing a Maglock, 18/2 shielded wire is recommended. Pull the 18/2 shielded wire through the opening of the box enclosure, making sure the ends are stripped and prepped for installation. 

Remove the Reader 2 terminal block, as labeled in the illustration above. (The Reader 1 terminal block can also be used.) Insert and secure the red wire from the Maglock into the positive output. Replace the terminal block. 

NOTE: If using Bosch or WBOX brand REX devices, they need to be wired to NO (Normally Open) and C (Common) instead of NC (Normally Closed) and C (Common).

Pair Maglock to REX Device

A REX device is specifically designed for indoor applications and features a passive infrared sensor. It is mounted over the door on the inside of the door frame. They detect when somebody approaches the door, and will deactivate the lock, allowing persons to exit the space. The sensitivity of the REX device can be adjusted for long-range or short-range applications and includes an adjustable time-delay. 

This illustration shows the maglock and REX wiring connections to a Single io controller. 

(A) Maglock - When installing a maglock, it is typical to install a REX at the door for free egress. Run an 18/2 wire from the maglock to the door controller. 

NOTE: If possible, when installing a maglock, avoid using and wiring up the bond sensor at the maglock for a DPS. A bond sensor is a built-in DPS on a maglock. For some unknown reason, it is not compatible with our programming. When a DPS is required, install an actual DPS. 

(B) REX - The REX is mounted in the desired location with an 18/5 wire from the REX to the controller (18/3 for a non-powered REX). Wire the REX to the controller and maglock as shown above. If reporting is not needed in the system, eliminate the green wire shown in the illustration. 

NOTE: If using Bosch or WBOX brand REX devices, the REX device switches needs to be set as "Fail-Safe", not "Fail-Secure".

(C) Jumper - Use the designated (+) or (-) board voltage out of NO and NC. If the jumper is off, the relay is a standard dry contact needing input into common (C). In the above diagram, the jumper is placed on the (-) side to operate the maglock. 

A motion detection REX device should ALWAYS be paired with a maglock and must include a PUSH TO EXIT (or REX button) per code requirements.

When installing a REX device, 22/6 shielded wire is recommended. Pull the 22/6 shielded wire through the opening of the box enclosure, making sure the ends are stripped and prepped for installation. (Coil the unused blue wire so it won’t interfere with the installation process.) 

• Connect a wire from the REX negative (V-) to the Reader 1 or Reader 2 negative of the door controller terminal block. Replace the terminal block. 
• Connect a wire from the REX positive (V+) to the Reader 1 or Reader 2 positive of the door controller terminal block. Replace the terminal block. 

 

• Connect a wire from the REX Common (C) to the NC (Normally Closed) door controller terminal block. Replace the terminal block. 

• Connect the green wire from the REX Normally Open (NO) to the B port of the door controller DPS terminal block (if reporting is needed). 
• Connect a wire from the REX Normally Closed (NC) to the maglock (-) terminal.

The green wire is optional and used to report a Request to Exit at a door. Remove the AUX terminal block and insert and secure the green wire into input B. Replace the terminal block.

Jumper

Because we are cutting negative, place the jumper on the top two pins. This will force a negative polarity out of the main relay. 

PUSH TO EXIT or REX Button

In the event of an emergency, a PUSH TO EXIT or REX button must be included (per code requirements) when connecting a REX device to a maglock. A push-to-exit button does exactly what its name implies: It allows you to exit when you push it if your door doesn’t open with the REX or traditional handles. It is installed on the inside of a room and is wired to the door's electric lock.

NOTE: For the button to serve its purpose, the door on which it’s installed needs to have an electronic lock. When the button is activated, it sends a signal to the lock and the corresponding lock opens.

Wiring a REX / REX Button

When adding a REX button to a maglock and REX motion device, run a wire from the REX button's NC (Normally Closed) connector to C (Common) on the REX motion device. 

Run another wire from the REX button's C (Common) to the Single io door controller's Normally Closed (NC) connector. 

A REX button is installed inside a door (usually on the door frame). When pushed, it triggers the lock to release and open the door. REX buttons are generally illuminated (backlit) so that they can be found easily in emergency situations.

A typical REX button has 5 wires (+, -, C, NC, and NO), although only four are needed for normal operation. Two wires (+, -) will power the LED, and two wires (C and NC) or (C and NO) will serve as signal wires that connect to the rest of the installation components (the lock and reader).

1. Connect and power the LED on your REX motion device.

• Connect the + and - on the REX using a 12/24V power supply. (If the button does not light, it may be necessary to change the polarity of the LED. Swap the wires on the button’s terminals and plug in the button again to test.)

2. Connect circuit signal wires to Common and Normally Closed. 

When wiring a fail-safe lock, a closed (series) circuit must be maintained to continuously power the lock.

• Connect the positive (+) lead of the power supply to C (Common) on the REX.
• Connect the REX's NC (Normally Closed) to C (Common) on the circuit's hardware component (motion sensor, maglock, or reader).

To test this connection, you will need to wire the button to power.

3. Connect and power the REX. This connection provides power to the REX button.

• Connect the REX button negative (V-) terminal to the power supply negative lead.
• Connect the REX button positive (V+) terminal to the power supply positive lead.

When the power supply is plugged in, the button's LED button should turn on.

As long as the rest of the circuit is completed, when the button is pressed, it should open the circuit and release the door lock.

REX 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 detector first sees 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

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

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

Table 3: DIP Switch Settings for Relay Mode

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

 

DIP Switch 6 - Resettable / Non-resettable

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.

Table 4: Resettable / Non-resettable DIP Switch Settings

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

 

Providing Power to the Board

Now that the controller is wired and ready to go, the board needs to be powered.

Pull 18/2 wire through the knockout and into the enclosure. Make sure the ends are stripped and prepped for installation.

Remove the 12-24V AC/DC terminal block and insert and secure the red and black wires. Replace the terminal block. NOTE: The single door controller is NOT polarity sensitive. 

The single io accepts 12-24V AC or DC, however, it is most common to use the included transformer to power the controller. Connect the 18/2 wire from the controller to the transformer.

Attach the red wire to positive (+), and the black wire to negative (-).

Plug in the transformer to power the board.

Backup Battery

It’s always important to install a backup battery. The recommended battery for a single door controller is a 12 volt, 1.2 amp battery.

Plug the leads from the battery into the power terminal block (red wire to +; black wire to -) as shown and slide the battery into the enclosure. 

After the door hardware has been installed and the Single io controller has been powered up, it's time to reconnect the door to secure the wiring inside the box. Secure the lid by inserting and fastening the screws that were supplied with the kit. The Single io is installed and ready to be configured.
