How to Wire the Zamel TRM-12 to a SkyBell Camera

Caution: Always work on a non-energized electrical circuit. Confirm no one is working with or near live wiring. If surface mounting, install the included protection shield so the 230 V AC input terminals are covered.

1. Connect mains/live 220–240 V AC input power to the 230 V AC input (supply) terminals on the top left corner of the unit.
2. Connect the doorbell wiring to the 12 V AC output (load) terminals on the bottom right corner.
3. Connect the opposite end of the wiring to the doorbell camera and chime according to the SkyBell installation guide.
