Many of these older modules have a use today – so we thought that it might be a good idea to give you a quick overview.
Delay Release ModuleAT – 065 DRM
The delayed release module was originally designed to allow an installer to “shunt” out a Passive Infrared detector on an exit route.
As soon as the unit is triggered the relay energises for a preset time – time period 0 – 55 seconds.
AT – 355 AC / DC
The AC to DC convertor has been designed to supply a regulated 12v DC supply.
The unit’s primary function is to work with door entry systems that only supply 12V AC to the magnetic lock. The unit is intended as a useful addition to supply 12v DC for uses such as key fob entry systems and door intercom systems.
Its small size makes it a very useful device not only for door entry systems but other applications where a small DC power supply with good regulation is required.
AT – 141 TRM
The transistorised relay module requires a permanent 12Volt DC supply.
It is triggered from a very low current source, such as communicator ports on alarm control panels. Its function has been “swept up” and is available in the Ultra Universal Relay AT – 182.
However, it is still an extremely useful product in its own right where small size and cost matter.
