8028 SIP Doorphone (G2) FW 3.2
The door control relay is used to maintain power to the door lock (NC and C contacts)
which is interrupted to release the door. Magnetic locks may require override systems to
allow safety exit in the event of fire.
Power Supply
The Doorphone Controller provides an auxiliary 24 V (0.25A using power supply, 0.5A
using PoE+, not available with regular PoE) power supply which is suitable for common
types of door strikes. If set to follow door control, then this terminal can be wired directly to
the door strike (if compatible), without needing to be also wired through the relay.
If more current or a different voltage is required, then the customer must provide a
matching power supply for the electric strike or magnetic lock. Maximum switching
capability of the 8028 door control contacts is 1 A, 30 V.
