zap ACC250 Slim and Compact Exit Buttons
Exit Buttons
This guide covers the slim exit buttons which are made from zinc alloy with a
matt finish. Their slim footprint means they can fit most locations and come
supplied with their own back box.
This guide also covers the compact exit buttons, just 53mm wide with a built-
in back box. The options available also include the LED illuminated ACC253
model.
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 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 pressed 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
Connections – ACC200
For operation with a door access control panel and lock, the exit button is
provided with NO/COM terminals.
Connections – ACC202, ACC250-252
For operation with a door access control panel and lock, the exit button is
provided with NC or NO and COM connection wires.
Connections – ACC253
For operation with a door access control panel and lock, the exit button is
provided with NC or NO.
The ACC063 also has a built in blue LED which requires 12V DC (not supplied
with the product).
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.
