PUSH TO EXIT or REX Button
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.
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 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
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).
When adding a REX button to a maglock and a 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 so that they can be found easily in emergency situations.
1. Connect and power the LED on your REX motion device.
- Connect the + and - on the REX button 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.
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.
