5.2 Replacement of Components
All components used in the control panel have been chosen for high reliability and long life. The
manufacturers’ data on the following items indicates that they may have a life expectancy of less
than 15 years and so may need to be replaced in the future.
5.2.1 Lithium Standby battery
CAUTION: A Lithium Battery is used for Data Retention.
Replace only with the same or equivalent type. Contact the Service Organisation for
Replacement CPU Card.
Manufacturer’s expected life
-
In excess of 10 Years
Recommended replacement
-
10 years for panels in continuous service. 4 years for CPU cards
held as spares and not powered up.
5.2.2 Liquid
Crystal
Alphanumeric Display
Manufacturer’s expected life
-
In excess of 10 Years.
Recommended replacement
-
When the display becomes difficult to read.
The LED backlit liquid crystal display gives a life that is significantly better than most other
display technologies. The contrast of the LCD will gradually deteriorate as this part ages. This
item should, therefore, be changed when normal contrast starts to fade.
5.2.3 Standby
Batteries
Manufacturer’s expected life
-
3-5 years at an ambient temperature of 20 Celsius, NB life
decreases approximately 50% for every 10 Celsius increase in
temperature.

Before installation.
New Batteries require ‘top charging’ prior to being put into service.
Yuasa recommend top charging at 28.8V DC for 15 – 20 hours for batteries up to 6 months
old from date of manufacture.
It is normal for lead-acid type batteries to discharge hydrogen while being charged. The
panel is adequately ventilated to dissipate this hydrogen.
DO NOT seal the panel enclosure or mount the panel in a sealed enclosure or cavity.
Dispose of batteries in a responsible manner and in accordance with any local
regulations.
