Controlling a T-Max timer

GateKeeper can be used to control a T-Max timer for tanning.

• Connect 12VDC power to the T-Max timer through the Gym Assistant controller relay.
• The controller relay should be configured as Normally-Open (same as for a door strike).
• In GateKeeper / Access Points, Relay Open Time should be set to the desired number of minutes * 60, e.g. set to 600 for 10 minutes of tanning.
• The reader should be mounted inside of the tanning room, rather than outside of the door.
• Tanning control will need to live on its own controller (separate from door controller), since Relay Open Time must be set the same for both doors on a controller.
