SPCA210.100 2-Door expander

The SPCA210.100 2-door expander extends the SPC controller with advanced door control functionality for 2 entry doors or 1 entry/exit door. The device features 2 Wiegand/Clock&Data interfaces, 4 LED control outputs (1 void / valid per reader), 4 zones (1 position- and 1 opening switch per door), 2 relay outputs (1 lock per door) and an on-board buzzer to signal "door open too long" events.To allow greatest flexibility, the zones and outputs are freely programmable for other purposes if not used for door control. Up to 512 priority card holders can be stored on the expander for standalone operation in case of communication loss to the control panel. The expander comes in a plastic housing with front tamper protection and features also an X-BUS status LED and on-board buzzer for easy device identification and extensive self-diagnostic capabilities.
