Exit Buttons
This guide covers the hygienic and convenient range of contactless buttons. These buttons can be activated without touching them to release the door, simply put your hand near the button to unlock it. The sensitivity can be adjusted to detect at different ranges to suit the installation.
User Information
- There are no user-serviceable parts, opening or attempting to repair the product will void the warranty.
- Do not install or use the device if the wires connected are damaged or have been subjected to water ingress.
- Shut off all power to the access control system before wiring this device.
- Maintain a clean and safe environment at all times.
Definition
NO (Normally Open) – This is a contact that remains open (as default)
until activated, during the “active” state the contact provides a closed
circuit and starts conducting.
NC (Normally Closed) – Is the opposite of a NO contact. The contact will
remain closed (as default) until activated, during the “active” state the
circuit breaks and stops the current flow.
Setup Example
Exit buttons are used in access control systems to provide a momentary contact
signal to the access controller to open a magnetic lock. This example shows a
“Fail-safe” scenario. When the exit button is activated the access control
power supply then releases power from the lock, and if power is lost then the
lock also releases. Wire in NO or NC depending on the access controller used
and also on the required state of the lock during a “Fail-safe” or “Fail-
secure” scenario.
Connections – ACC351-352, ACC361-362
For operation with a door access control panel and lock, the exit button is
wired with NC or NO and COM.
A permanent DC 12-24V supply is required to operate the contactless exit
buttons (not supplied with the product).
Sensitivity & Time Delay Adjustment
Troubleshooting
If the exit button is not activating the lock then there is likely a shorted
wire, open circuit or some other failed device in the circuit.
To identify where the fault is, each wired connection in the circuit needs to
be tested; working from the push button progress through, including the
keypad, the access controller, power supply and the magnetic lock.
If the fault is with the access control button then check the connection wires
for continuity and for trapped wires. Check for water ingress on the wired
connections. Check the polarity in the power connections and ensure the
connections are connected to the proper terminals.
