If you are looking for high-security access control – Interlocking is an ideal solution. Interlock systems control the locking of two or more doors so that if one door is open or unlocked, the remaining doors refuse access.
Each door is electrically locked and monitored. The control electronics then generate a control signal to indicate when the door is closed and secure. Each controller also has a control input that will prevent the releasing of the locking device. By cross-connecting these control signals, the door controllers communicate the door status and only open one door at any given time.
The simplest interlock Access Control System would have two doors, although standard systems can be made up to four doors. Individual doors may be controlled by an on-line or stand alone controller and/or an interlock controller.
Interlock Controller 2 Door
These controllers provide all the electronics to control and monitor a door and provide an interlock with another door. Trigger inputs drive a lock timer that can be adjusted from 3 to 40 seconds. Door monitoring allows ‘door forced’ and ‘prolonged door open’ alarms to be generated. NB. the current limit of the mains derived supply is 2.0 amps at either the 12 or 24V setting. However, 0.5 amps of this should be reserved for charging the batteries and running internal electronics. This leaves 1.5 Amp DC for externally connected loads.
4 Way Interlock Programming Module
For use with any combination of access controller and or interlock controller (2089, 4163, 4001). The module allows easy and flexible programming of interlock systems. It greatly simplifies wiring and system debugging. This unit takes its supply from the other controllers. A 12 way DIP switch allows the interlocking to be programmed in any combination. On board, indicators show current interlock signal status.
An “Interlock Programmer” is used to simplify connecting these controllers together. It also allows for easy and flexible programming of the interlock system. A 12 way DIP switch allows the interlocking to be programmed in any combination. On board, indicators show current interlock signal status.
