Connecting the External Time Signal
CAUTION: Be sure to pull out AC cord from AC outlet before connecting wires of the
External Time Signal. Improper connection may cause a malfunction of the unit.
Also refer to "Attaching the Wire Clamp" to secure wires with the wire clamp.
If external signal(s) are required, the addition of a relay (not supplied) will be necessary.
Please consult your local electrician.
When a signal is activated the internal contacts close completing the circuit. These internal
contacts are "dry" and supply no voltage. Voltage applied to these contacts must not exceed
30 volts. An external relay must be used to activate signaling devices.
Recommended Relays: (Or similar line voltage switching relays)
