Engineer’s Specifications
Specifications (Continued)
The Fire Alarm System shall be designed with remotely
located Notification Appliance Circuit (NAC) Expander/
Power Supplies for the support of notification appliances.
The remote Power Supplies shall be fully supervised and
shall provide 8.0 Amps. of notification appliance power and
1.5 Amps. of auxiliary power output. The NAC Extender
Panel shall be able to select strobe synchronization proto-
col via an internal dip switch. There shall be five selectable
protocols available. The NAC Extender Panel shall syn-
chronize all outputs simultaneously. The NAC Extender
Panel shall be able to use existing notification appliance
circuit’s end-of-line resistors in the range of 2K – 25K ohms
for retrofit applications. The internal battery charging circuit
shall charge up to 26 AH batteries. The NAC Expander/
Power Supply shall be a Gamewell-FCI FireForce 8.

31081
SCE-95 mounting plate provides a means to install two (2)
SCE-95 modules. The addition of SCE-95s provides a
means to run on FF8 outputs via a panel command on an
SLC. The 31081 mounts over the main PCB and is hinged
for access to FF8 terminal.
