b) JL OFF will cause the unit to latch ON until manually reset. Install the 2.2K Ohm (EOL) resistor provided at a
Key Switch or Push Button to perform this manual reset operation and to supervise this connection as shown in Fig
1a.

Alarm/Trouble Output
a) Power Fail: When DC Power fails or PTC activates this will cause the dry contact "Form C" relay to de-energize.
b) Fire Alarm: When the FACP activates this will cause the dry contact "Form C" relay to de-energize.

Cascade Connection
Two (2) or more HPMOM6 units can be connected together as follows; Connect the Fire Alarm relay C and NC terminals
from the 1st unit to the "FIRE INTRFC" of the 2nd unit (not polarity sensitive) and remove jumper JR of the 1st unit. If a
3rd HPMOM6 is used, JR must be removed from 2nd unit and so on for each new addition. See Fig. 1a.
8.
Power Board Connections
Connect the "AC Fail" output "Form C" dry contacts to the monitoring device. In case of AC loss the relay, which is Fail
Safe, will de-energize within one (1) minute. Connect the Battery Fail output "Form C" dry contacts to the monitoring
device. If a Battery is not connected or improperly connected, the Yellow LED (L3) will turn ON within one (1) minute
and the Battery Fault output relay, which is Fail Safe, will de-energize.
9.
Power Up
When all wiring is complete and checked, switch ON the AC Power. The Green Led (L1) will come ON indicating AC
presence and the AC relay will be energized. Connect Battery observing the correct polarity. For 24VDC use the battery
link provided to connect the two (2) 12 Volt Batteries in series. Secure the enclosure with the 4 screws and with the Key
Lock provided.
NOTE: For UL603 or UL294 applications use a Tamper Switch (Catalog number HPVM3 available separately), and
included enclosure key lock. Connect the tamper switch NC outputs to monitoring device to notify of enclosure tampering.
