Operators Manual
2.4 Optional Power
The Primapak II storage battery supplies a source of 12-16 Volt DC power to the Primalert using the converter plug connection. The plug is a Switchcraft #760, or equivalent, with the sleeve negative and pin positive. The current drain at background radiation levels is about 25 mA, and about 250 mA at full alarm levels.
The optional Primapak II Back-up Battery Pack, Model No. 05-441, is available as an optional power source for the Primalert. The Primapak II consists of rechargeable gel cells and circuitry that switches the Primalert to battery operation if line power is lost. When AC power is present, the battery is automatically recharged. Fully charged cells provide approximately eight hours of operation under alarm conditions or more than 32 hours of operation. The Primapak II includes a 120VAC/16VAC converter and interconnect cable.
