Main Power Supply
The MS-5024 provides filtered power for operating the fire alarm control panel, operating external devices and oper-
ating the standby battery. The power for operating external devices is limited. Use Table A-2 (standby or nonalarm)
and Table A-3 on page 65 (alarm) to determine if external loading is within the capabilities of the power supply.
Concerning 4-wire smoke detectors: be sure to power detectors from TB4, Terminals 3 & 4.
Note that all external devices are connected to TB4 only.
Notes:
1.
Refer to the Device Compatibility Document for 2-wire smoke detector standby current
2.
Must use compatible listed Power Supervision Relay
