Using the
MIR-425/U
2-wire smoke detector. See
Appendix A
on page 33 for other available smoke detectors.
Total Alarm Current
• Must be 2.75 amperes or less for FA-201, FA-202, and FA-204. Indicating Circuits not to exceed 2.4 amperes.
• Must be 6 amperes or less for FA-204E. Indicating Circuits not to exceed 5 amperes.
Battery Selection
• Multiply (C) by 1.20 to derate battery.
• Use BA-1065(6.5AH) Batteries for the FA-201, FA-202, and FA-204 which charges up to 12 AH Batteries.
• Use BA-110(10AH) Batteries for the FA-204E.
• The FA-204E will charge up to 24AH batteries if they are in an external Mircom BC-160 Battery Cabinet.
IMPORTANT NOTICE
The main AC branch circuit connection for Fire Alarm Control Unit must provide a dedicated
continuous power without provision of any disconnect devices. Use #12 AWG wire with 600-volt
insulation and proper over-current circuit protection that complies with the local codes. Refer to
Appendix C
on page 38 for specifications.
