Modern electronics are generally regarded as extremely reliable but components and circuits can alter their characteristics, deteriorate with age and can even become corrupted by other equipment.  Also certain items such as batteries and relays do have a finite life.  Regular routine servicing can often result in faults being diagnosed before they actually manifest themselves and this can therefore save secondary damage.  This can therefore avert a failure and consequential loss before the fault becomes apparent.

The following work should be carried out regularly by our trained and experienced personnel: -

• Check the battery back-up power changeover relays.
• Check regulated voltage and charging current
• Check battery condition – both physical and internal values.
• System performance & operation both generally and on power failure

A faulty battery can damage the power supply PCB.  The result of this is both an expensive repair and a failure to operate in the event of a power failure.

• Check dialout pulses and break ratio
• Physical examination for e.g. corrosion – on one site we have recently attended had 'encrusted' fuses resulting in intermittent operation.
• Predict and identify any weaknesses that could result in an otherwise unforeseen failure.
• We have encountered systems where:-
• parts either no not work,
• have been disconnected or even removed,
• someone has changed the battery pack for 'something similar' which has resulted in damage to parts of the circuits.
• all without the sanction of management.

Other advantages of servicing include:-

• Shows that unit has been tested and inspected in line with animal welfare (Welfare of Livestock Regulations 1990) and insurance requirements.  Obviously customers should be carrying out a physical inspection and test every week two.
• Preventative servicing is designed to avoid the inconvenience and expense of emergency callouts and repairs. 
• Helps to show due diligence should you have a loss
