Specifications
AC Power - TB8
MS-9200(C): 120 VAC, 50/60 Hz, 2.3 amps
MS-9200E: 240 VAC, 50 Hz, 1.2 amps
Wire size: minimum #14 AWG (2.00
mm
2
) with 600V insulation
Battery (Lead Acid Only) - J3
Maximum Charging Circuit:
Normal Flat Charge — 27.6V @ 0.8 amp
Maximum Battery Charger Capacity: 18 Amp Hour (MS-9200 cabinet holds maximum 12 Amp Hour batteries. Bat-
teries greater than 12 Amp Hour, up to 18 Amp Hour, require Fire•Lite BB-17F or other UL listed battery cabinet).
For 25 to 120 Amp Hour batteries, use the CHG-120F Battery Charger
only
if the newer MS-9200 main circuit board
with jumper JP1, is installed.
Note: Jumper JP1, on the FACP main circuit board, must be cut to disable FACP bat-
tery charger when using the CHG-120F
.

Power-limited circuit
1. Total current for special purpose power, nonresettable power, 4-wire smoke power and two NACs
must not exceed 6.0 amps
.
Total external system current in excess of 3.6 amps requires XRM-24 Transformer (XRM-24E for MS-9200E) and 12 AH or 18
AH batteries, not 7.0 AH.
2. For power supply calculations, refer to Appendix A.
3. Total current for resettable 4-wire smoke detector power and nonresettable power must not exceed 600 mA.
