Connecting the External Time Signal
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)
1) Acroprint P/N 01-0230-000 (Grainger P/N 2E866)
2) Grainger 2E866 (HoneyWell RA89A1074)
