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.
2.5 Routine Cleaning
Do not immerse the Model 05-437 Primalert. The
unit is not waterproof. Liquid could damage the
circuits. The unit should be kept clean and free
from dirt and contamination. The unit may be
cleaned by wiping with a damp cloth using any
commercially available cleaning or decontaminating
agent.
2.6 Attaching a Ground Wire
If required, use the following procedure to attach a separate ground wire to the instrument:
1. Loosen the screw in the center of the back cover.
2. Remove the back cover.
3. Attach a wire to the ground terminal by running it up through the small hole between the jacks.
At least #16 gauge wire should be used for this
purpose.
