type of input voltage. When AC power fails, the battery will provide 15 minutes of
holdover at full load (20 watts) or 8 hours at light load (2 watts).
The 1151A1 and 1151A2 power supplies can be used to supply local power to
ISDN-T 65xx, 75xx, and 85xx series voice terminals connected to a DEFINITY
Communications System G1, G2, and G3, a DEFINITY ECS, and to the DCP
7444 and 8434/8434DX voice terminals which need auxiliary power for their
vacuum fluorescent displays. You also need auxiliary power if you are using an
8411 voice terminal or if your voice terminal has a ZE801A or XM24 expansion
module connected to it. These power supplies can also supply auxiliary power to
adjunct equipment such as the S201A, CS201A, or SoundPoint speakerphones or
a 500A1 Headset Adapter attached to any currently manufactured analog, DCP, or
ISDN-T voice terminal equipped with an Adjunct jack.
