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. zap-ACC351-352-Contactless-Exit-Buttons-

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.
