S1145B Battery Pack Operation Manual Description The S1145B is an improved direct replacement for the following Lucent/ATT ISDN battery packs: 1147B1, 1148B1, 1149B1, and KS-21906. Features include 8 amp hour battery capacity and compatibility with the existing wall mounting plate and connection wiring. The S1145B Battery Pack’s microprocessor-based controller monitors charge status and automatically performs a periodic battery test to guarantee the holdover capability of the pack.
S1145B Battery Pack Installation Instructions The S1145B Battery Pack mounts on an existing Lucent/ATT Wall-Mounting Plate. For a rack mount or a direct wall mount application, contact SEI regarding a BP-8U External Battery Pack.
b) To prevent battery discharge, do not install the fuse in the S1145B Battery Pack until the unit is ready to be connected to a Power Unit. Do not store the S1145B Battery Pack with the fuse installed 7) Operational Test The following operational test should be done on each unit immediately after installation. (The SEI S1145R Power Unit provides a continuous float charge voltage to the battery. This allows the status indicators on the S1145B to be ON continuously.
iv) Verify that the Battery Pack fuse is not blown. b) Power Unit Fault Indication: If the Battery Charge Status LED is constant or flashing red, the Power Unit is not charging the Battery Pack at the recommended charging voltage. The Power Unit should be replaced. c) Replace Battery Indication: If the Battery Test Status LED is flashing red, the holdover capability of the battery is significantly diminished. The battery should be replaced.
S1145R Power Unit Operation Manual The S1145R Power Unit is a direct replacement for the Lucent/ATT 1145A, B1, and B2 ISDN power units. Features include 200 watts of output power, a low voltage battery disconnect and compatibility with the existing wall mounting plate and connection wiring. The S1145R Power Unit provides a nominal 48 volt DC output voltage at up to 4.2 amps with the ability to power up to 96 ISDN phones. Connectors are provided for power to an 1146 block and a backup battery pack.
S1145R Power Unit Installation Instructions The S1145R Power Unit mounts on an existing Lucent/ATT Wall-Mounting Plate. For a rack mount or a direct wall mount application, contact SEI. PARTS LIST 1) One S1145R Power Unit 2) One Battery Connection Cable 3) One Distribution Unit Power Cable Adaptor 4) One AC power cord 5) Two #10-32x0.5” Screws 1) Remove Existing Power Unit a) Unplug the AC Power Cord from the electrical outlet. Disconnect the AC Power Cord from the left side of the unit.
6) Power-up and Test a) Power the S1145R by plugging the AC power cord into an unswitched outlet. b) Verify that the LED on the Power Unit is constant green. If it is not, check the AC power cord connection at the Power Unit and the power outlet. c) Verify that the green power LEDs on the NT1s connected to the 1146B Distribution Unit are on. If none of the NT1s are powered, check the connection of the Distribution Unit Power Cable Adaptor at the Power Unit and the Distribution Box.
