22 - PC3500TX Terminal Installation & User’s Guide

A P P E N D I X B

Optional Signal Device

With a bell relay, you can program when bells or other devices will ring using the Bell Wizard in your Terminal Manager software. Call Lathem to purchase a bell relay. You should have a qualified/certified electrician connect your signaling devices to ensure proper connections and prevent damage to your equipment. Note: The PC3500TX relay is only a switching device and does not supply power to the ringer.

To connect your signaling device(s)

If not already installed, mount the relay module to the inside of the mounting bracket. See the diagram below for details on connecting your signal devices. Connect the relay module to the RJ-11 DI/DO connector on the back of the terminal and place the terminal on the mounting bracket.

*NOTE* You must use an external power source, such as Lathem’s RB8 relay booster, for your bell ringer. When connecting to the RB8 relay booster, connect the Common from the PC3500TX bell relay to the RB8’s Ctrl In A connection point and the Normally Open to the RB8’s Ctrl In B connection point.
