RELAY BOX INTERIOR
Each relay has circuits to control both 24 VAC and/or 120 VAC simultaneously
so that a service sign as well as the service solenoid can be operated from
the same relay.
 Plug in relays for ease of serviceability.
 Each relay has
2 fuses.
 Built in spare fuses and fuse tester near the center of the box.
 Each relay can be programmed to flash, eliminating the need for field
installed flashing relays for signs.
