Full monitoring of mains failure, battery disconnection and total power failure is provided. Four and ten amp units have additional monitoring of earth fault and low battery voltage conditions.

Enclosed units are mounted in high quality, fully welded boxes with a key lock and a generous battery space and are available as flush or surface mounting.

Standard finishes are two-tone grey or all light grey, however other colours and finishes are available to special order.

Chassis mounted versions are easily secured by four fixings through the integral heatsink/mounting plate.  Push on battery leads are supplied with each unit, complete with a linking jumper for two, twelve volt batteries.

N.B. Life expectancy of valve regulated lead acid (the VRLA) batteries is approximately 5 years from the date of manufacture NOT the date of installation.
