INTERNAL SHORT-TERM BATTERY BACKUP (BATTERY OPT = NiMH)
An internal short-term battery backup is available as an option. It can power
the PS-1000 from fifteen (15) to forty-five (45) minutes (depending on alarm
status) with fully charged batteries. Only use two 8.4V NiMH batteries with a
capacity of 170mAh (milliamp-hour) or better..".#!0'! !%1$5'+

Note: The BBU1000 is shipped with the battery plug, TB2, disconnected. The user must insert this plug
onto the TB2 header located on the BBU1000 unit for the battery to function properly. Also, the TB3 power
cable must be connected to the GD-1000 meter (The GD-1000 header is TB11). The battery is fully charged
before it leaves the factory. However, the battery will loose some of its charge over time if it’s not being
charged by the BBU1000.
