Installing The External Battery Assembly
On The DXP Plus Digital Communications System
1.0 Introducing The External Battery Assembly
The external battery assembly is for use with the DXP Plus digital communications system. Unpack and carefully
inspect all equipment for shipping damage. Notify the shipper immediately of any damages found. Verify that the
packages contain all parts and accessories needed for proper installation and operation. The assembly includes the
following items:
•
Batteries: Five 6-volt, 50 ampere-hour, (Comdial product code BT000-141), charger unit and interface cables.
•
Metal enclosure with wire harness, includes combination circuit breaker, on/off switch
Should the AC power to the system be interrupted, one external battery assembly provides the following
minimum power capability:
•
1.0 hour of operation for a fully loaded system.
Calculate the minimum battery backup time provided by an external battery assembly to a fully configured DXP
Plus system using the following formula:
T = Back-up time in hours
K = 0.82 (Constant)
e = 50 (ampere-hour capacity of battery assembly)
N = Total number of stations
Example:
Assume that you have installed a DXP Plus with three cabinets supporting 472 telephones and containing one line
board along with a battery assembly to provide back-up power.
During AC operation, the battery assembly accepts re-charging current to maintain the voltage potential of its
batteries at an operational level.
NOTE: The external battery assembly requires approximately 10 hours to completely re-charge to full potential
after it has been completely discharged and, in some cases, when initially installed.
T =
Ke
1 + [(0.084) (N)]
T =
(.85)(50)
41.0
1 + [(0.084) (472)]
=
40.65
= 1.0 Hour
