Output Relay
Function Setup
The Cellular Alert has a relay that may be used to trigger an ac-
tion such as turning on a fan or turning on an irrigation system.
This action will be triggered when the sensor crosses above or
below the Limit threshold that was determined when program-
ming the control panel.
The internal relay is limited to 250 V, 1 Amp AC or DC. Higher
voltage or current than this will require an interface relay. The
maximum switching power is 60 W or 60 VA.
The terminal block for the
relay appears to the right of
the WatchDog logo on the
control panel. It contains
three wire terminals,
NO—NormallyOpen
COM—Common
NC—Normally Closed.
To insert the wires, press on the white button and insert the wire
into the corresponding terminal. Release the button when the
wire is in place to lock it.
To avoid short circuiting, ensure
that no bare wire is exposed above the terminal block.
