OPTIONAL INSTALLATION/CONNECTIONS
Connecting the External Time Signal
If external signal(s) are required, the addition of a relay and signal control board (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.
