Primapak II Backup Battery Pack

The Primapak II consists of rechargeable gel cells and circuitry that switches any Primalert 10 to battery operation if line power is lost. When AC is present, the battery is automatically recharged.
 
Fully-charged cells can provide approximately eight hours of operation under alarm conditions or more than 32 hours of quiescent, no-alarm operation. Primapak II comes with a 120 VAC/12V converter, wall-mount bracket.
