BPT UK TRADESMAN TIMER – TT/2
The timer is a fully programmable 7 day time clock and is primarily intended to provide inhibit and enable periods
for Tradesman push button on all BPT Video and Audio Entry Systems.
The delay ‘on’ to lock release, provided by clean changeover contact from the TT/2, can be varied from 2 to 5
seconds. The provision of N/O or N/C contacts allows connection of virtually any configuration of lock release.
