Fire and To comply with UL 985 and 864 listing standards for fire alarm
Fire/Burglary systems (effective March 1, 1989), the total combined
Systems continuous and alarm current draw for the system during alarm
conditions must be limited to 1.4 A (1400 mA) provided by the
primary power supply (rectified AC). If current draw for the
system exceeds 1.4 A, remove connected devices until the
current draw falls below 1.4 A, then connect the removed
devices to a D8132 Battery Charger Module or to an external
power supply (see Figure 19 ).
10.2 VDC
SDI Bus A (+): 9 VDC (15,000 ft. [4,572 m] max.)
SDI Bus B (-):
9 VDC (15,000 ft. [4,572 m] max.)
Connection RJ31X or RJ38X jack can be interfaced with the panels.
Two TelCo Lines Radionics D928 Dual Phone Line Module required for two
phone line service. Supervision supplied by the panel.
