BSB Electronics has announced that all their industry-leading Progeny access controllers have interlocking capability built in as standard. BSB’s Managing Director, Brett Burby believes this makes their controllers unique. He says “Having interlocking features built in as standard makes our controllers a cost effective option for installers and end users alike.” BSB offer an extensive range of controllers capable of providing interlock with another door or access control unit. Trigger inputs drive a lock timer that can be adjusted from 3 to 40 seconds and door monitoring allows door forced and prolonged door open alarms to be activated. BSB also offer an interlock programming module for use with any combination of controller. This module allows easy and flexible programming of interlock systems and greatly simplified wiring and is ideal for installation in banks and building societies.
