Wiring Diagram
Setting the Address
Each SLC device must be assigned an address prior to installation. The address is set using either the hand held device programmer or the addressing feature on the PFC-6000 /PFC-8500 Series control panels.
Before connecting a device to the SLC loop, take the following precautions to prevent potential damage to the panel or device:1. Power to the device is removed2. Field wiring is correctly installed.3. Field wiring has no open or short circuits.

It is possible that the relay contacts on the TRM-4 may be shipped in the non-normal / activated state. To ensure that the internal relays are set to the normal state, connect the module to the SLC loop and reset the control panel before terminating the wiring to the dry relay contacts.
