A range of timers and relays to compliment any access control system - from simple switching and lock release delay, to the control of timed free access through an electronically locked door, these accessories are essential for any engineers toolbox.

The TH Series of timers provide various weekly and daily programmes to control the automatic release of locks for "free access" periods.
Easy to programme, with LCD digital displays to give visual feedback, these timers allow up to 8 on/off schedules to be applied daily or weekly - in fact there are pre-set groups of days to assist in the set up of the programming.
The timers operate automatically but also include a manual override. They include an NCID battery for back up, and are available with different voltages.
The VHLR is a universal relay, which has an input of 12-24V ac/dc with a double pole changeover relay.
The delay module provides a 3 to 10 second delay on any "fail-safe" lock - when power is removed, the lock releases and once power is re-applied, the delay will operate before allowing power back to the lock.
