Terminals Use 12 VDC sealed lead-acid rechargeable battery (7 Ah, 18 Ah, or
4 38 Ah). The control panel supports up to 38 Ah of battery. If you
and 5 use two batteries, they must have the same capacity and you must
connect them using the D122/D122L.
1.4 A maximum at 12.0 VDC nominal (continuous supply) total for all devices
and outputs including the ZONEX connection, the plug-in module connector,
and Terminals 3, 26, and 30.
2.0 A maximum (1.4 A max for commercial fire) at 12.0 VDC nominal output for
all devices and outputs including the ZONEX connection, the plug-in module
connector, and Terminals 3, 6, 7, 26, and 30. Output can be steady or one of
three pulsed patterns depending on programming. Refer to Relays in the RPS
Help or in the Installer Services Portal programming tool (available in Europe,
Middle East, Africa, and China) Help.
Terminal 1.4 A maximum at 12.0 VDC nominal output. Continuous output is
8 interrupted by Sensor Reset or alarm verification depending on
programming. Refer to Relays in the RPS Help, in the Installer
Services Portal programming tool (available in Europe, Middle East,
Africa, and China) Help, or in the Control Panels (B9512G/B8512G)
Program Entry Guide.
To comply with UL 985 and 864 listing standards for fire alarm systems
(effective March 1, 1989), the total combined continuous and alarm current
draw for the system during alarm conditions must be limited to 1.4 A 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 an external power supply
as B520).
