Connecting AC Power
The alarm controller requires a 16.5V, 40VA transformer. While unplugged, connect the transformer to the AC terminals on
the controller. The alarm controller can be programmed to accept a power line frequency of either 50Hz AC or 60Hz AC. See
programming section [024], option [1].
Note: For UL/ULC installations use only 60Hz.
Note: For ULC S559 applications, Standex transformer (Model FTC3716) shall be employed for direct-wiring.
