SDC-550: Multiple Door Controller

NOTE: This controller is now end of line and limited stock is available.

This is a system controller, capable of connecting to up to 10 readers and controlling 2 full normal doors, 1 bi-directional turnstile or 1 booth/mantrap onboard. With the addition of Remote IO boards this can be expanded to 8 doors per controller. It has five relay outputs (potential free contact/powered output) and 6 programmable digital inputs. There are an additional 2 digital inputs that are initially dedicated as fire alarm and tamper inputs, however these can be overridden and used for any task. It can be connected to other controllers using a robust multidrop RS-485 network which has isolation that protects the controllers on the network from electrical spikes of up to 2.4kV. The unit comes with a 12Vdc 5A power supply with a battery backup of 7Ah and is mounted in a secure enclosure with a lockable door and mounting key holes on the outer edges.
