<br />The MS-5012 provides regulated power for operating the fire alarm control panel, operating external devices, and <br />operating the standby battery. The power for operating external devices is limited. Use Table A-1 (standby or <br />nonalarm) and Table A-2 (alarm) to determine if external loading is within the capabilities of the power supply. <br /> <br />Table A-1: Regulated Load in Standby @12VDC <br /> <br />Device Type # of Devices Current Total Current <br /> (Amps) (Amps) <br />Main Circuit Board 1 X 0.074 = 0.074 <br />ADM-12 (1 max.)
