NOTES
1. Building Interface Relay can be used for remote shutdown or alarm. Relay is energized during normal operation.
DPDT contacts rated 1/4 HP at 120VAC, 10A at 28VDC or 240VAC.
2. Other N.O. REPO devices may be wired in parallel to the N.O. REPO contacts. Other N.C. REPO devices may be wired
in series to the N.C. REPO contacts. Multiple REPO lamps and other 24VDC loads may be wired in parallel to the
REPO lamps. Maximum 24VDC supply available is 1 Amp total. Both N.O. and N.C. REPO switches are powered from
the same supply.
3. All auxiliary control devices and cabling to be field-supplied except as noted.
4. Overtemperature alarm contacts change state when unit overtemperature is sensed.
