Notes:
1. All wiring must be in accordance with Article 760 of
NEC or local building codes.
2. Polarity shown in active state.
3. For Compatible Solenoids refer to table below.
4. The maximum cumulative output current of the MPC-
REL must not exceed 3A.
5. REL-EOL module (P/N 500-696359) is required for
supervision of open and short circuits on the releasing
circuit. REL-EOL must be in the same enclosure or
close nippled to the last solenoid in the loop.
6. The MPC-REL requires an RPT-1 transformer.
7. A mechanical manual release must be employed to
meet NFPA 2001 requirements.
8. Releasing circuit maximum voltage line drop = 0.6V.
9. Wiring shown complies with UL864 9
th
Edition
requirements.
Note 1:
Single 12VDC and 6VDC solenoids are not supported. If 6VDC solenoids are used, four solenoids in series must be used.
If 12VDC solenoids are used, two solenoids in series must be used.
Note 2:
It is not permitted to mix one 12 VDC solenoid with any combination of 6VDC solenoids.
