The ET Timer is an expanded version of the AT/FT Time Delay products and can be added as an option to many of the company’s push buttons, key switches and sounders.

The new adjustable timers are powered from a 12 to 24 volt DC supply and provide an adjustable (one-60 second) time delayed DPDT – 3 Amp dry contact output. The timer can be triggered from either a normally open or a normally closed momentary dry contact or by switching the trigger input to the power source ground.

A field selectable jumper will allow the timer to execute a single timing cycle upon initial power up for application flexibility. Wiring terminals are provided for connection of all field wiring. Applications for the ET Timers include delayed re-locking control for electric locking hardware or as an alarm shunt. The device is also offered as factory configured to provide exit alarm and door prop functionality.
