FACP and DC20

With the addition of an Access Power Controller (APC), the DC20 can be deployed in applications with an existing Fire Alarm Control Panel (FACP) by means of the dry relays.

In the event of a fire alarm, the FACP sends a signal to the APC, which immediately disconnects the power supply of all locking hardware connected to the DC20. In the absence of power, doors that are wired as fail-safe will unlock.

Once the alarm has been dismissed, the APC will reconnect power to the locking hardware. Refer to the documentation provided with the APC and follow all manufacturer instructions related to your specific application.

Note: Consult Federal, State, and local authorities for all applicable regulations related to access control integration with fire alarm systems.
