Security System Maintenance – Prevention is Better Than Cure


It is important to ensure that your Intruder Alarm is maintained on a regular basis to guarantee that it will operate correctly at all times, unlike those that you regularly hear sounding as soon as there is a power cut.

If you are receiving a discount from your insurers for having an approved alarm fitted, they will expect the system to be maintained by an approved installer to ensure the alarm is fully operational.

If your alarm is Police Monitored it should be serviced every 6 months one of which may be carried out remotely.

Watson Alarms take the maintenance of our alarms very seriously, with this in mind we offer a fully comprehensive maintenance plan. DON’T BE FOOLED BY OTHER “MAINTENANCE CONTRACTS” OUR COST IS NOT FOR ONE VISIT ONLY!

Our full maintenance contract on new systems will include all parts to repair the system due to fair wear and tear.

This includes all battery replacements when required; all labour required to repair the system; and UNLIMITED CALLOUTS for the year. The first scheduled maintenance visit takes place approx. one year from the install date and we have a full 24 hour emergency callout control centre service.

Where a suitable modem is installed within the system, we will carry out an interim inspection midway through your service period remotely via our Maintenance Software whether the system is Police Monitored or not.

In addition, we will access the system remotely prior to the engineer’s on-site visit to ensure that the engineer is pre-warned of any possible problems that are highlighted and to make sure he has the necessary components available for your alarm system.

As the term implies, CCTV preventative maintenance involves regularly testing the functionality of CCTV surveillance equipment to reduce the probability of a malfunction or failure.

Maintaining systems regularly will ensure CCTV systems are working to their optimum performance and that images recorded and stored are fit for purpose, and are of evidence quality and could be used as admissible evidence for purposes of investigation or for use in courts of law.

Preventative maintenance is an essential part of ensuring continuous surveillance and helps to deter break-ins, theft and the overall security of the area(s) being monitored.

To avoid any lapses in surveillance monitoring, CCTV system maintenance is usually carried out whilst all devices are still in operation.

This regular inspection should be planned as part of the overall security system maintenance checklist requirements of the business or household.

It is also a good idea to organise the inspection date so that any spare parts that may be needed are readily available.

In summary, preventative maintenance increases confidence in the entire security system, and is often a written requirement as well as a condition of commercial building insurance.

The owners or operators of a CCTV system should normally be able to keep CCTV cameras free of everyday dust and obstructions, but any technical scheduled maintenance must be carried out by trained service engineers.

Watson Alarms offer a totally flexible CCTV maintenance solution which ensures your CCTV system is kept in optimum condition.

Our Standard Service Care Package is based upon a 4 camera system and includes 2 service visits per year (one in the spring & one in the autumn), all cameras will be cleaned and adjusted as required.

Where additional cameras are installed these will be added to the service agreement at additional cost.

The maintenance contract is inclusive of standard emergency call out Monday to Friday 9.00 – 17.30 (Additional Options Available). 

During the service visit our engineers will:

  • Verify that the number and type of cameras installed, as well as lenses, corresponds with records held by the Client.
  • Act on any previous notifications or issues reported by the business.
  • The camera checking component of the security system maintenance checklist should include comprehensive cleaning of the lenses and housings.
  • Once the camera is properly cleaned, the engineer is required to monitor all automated and remote control functions and that all camera movement, as well as the area of the premises they view, are not obstructed.

Once the camera is shown to be working as it should, the next step is to check the audio and recording equipment.

  • If there are any external cameras, ensure that any plants, trees or shrubbery do not impede the view, recording or any other function of the CCTV camera.

Most insurance companies will insist on this as a condition of the insurance, and the service will require the growth to be regularly cut back.

  • Check that all cables are properly mounted, or supported by the correct conduit, and that the insulating plastic is showing no sign of wear and tear.
  • Check that all indicator lights and pre-sets are functioning correctly.
  • Verify that all warning labels and notifications are present and clearly visible. This also applies to a full connection check of all components in the CCTV circuits.
  • Check that all fixtures and fittings that ensure that the CCTV itself is properly supported are in place. This examination should include looking for signs of physical damage and any form of chemical corrosion. Any damage should be repaired as soon as possible. Many business owners check that such repair work is possible within the terms of their maintenance contract.

Where the CCTV cameras are linked to the security and fire alarm system as such that the CCTV preventative checklist needs to ensure that the correct alarms are triggered.

Related to this test is ensuring that the ambient lighting does not affect the view from the cameras in the device.

The engineer is also required to check any log books or computer held data pertaining to the CCTV system and advise on any necessary updates relating to such data.

In order to comply with European and British standards and to ensure that an Access Control system or Door Entry system remains completely reliable, it is vital that it is maintained regularly.

Out Annual Preventative Maintenance package consists of 1 scheduled maintenance visit per year, listed below are a selection of the system checks that are carried out by our engineers during a routine preventative maintenance inspection / service visit.

  • Visual inspection of the system.
  • Check mains power supply including charging rates (where applicable).
  • Check battery power supply including charging rates (where applicable).
  • Check satisfactory operation.
  • Make adjustments as necessary.
  • Cleaning control components.
  • Log all test results.
  • Retrain the users on the use of the system (if required).
  • Check all locks and lock releases are working correctly.
  • Check all speech unit levels are correct.
  • Check camera and video monitors are operational and images are clear.

Once the Maintenance visit has been completed a full report (if required) will be sent out for reference and if required a quote for any further work found during the visit.

Maintenence contract does not cover damages or faults and damage caused through acts of vandalism.

Monitoring & Police Response

For increased security, you may wish to have your security system monitored.

A monitored alarm is one that is linked via the telephone line or cellular network or both to an Alarm Receiving Centre (ARC)

Monitored Systems

The system installed may be the same as (or similar to) a bells-only system, except that – when the alarm is activated – an integral modem informs the Alarm Receiving Centre via a burst of data much the same as a fax tone.

Dependent upon the signal received & the design of the Intruder Alarm System the Alarm Receiving Centre will be able to confirm if the alarm condition is unconfirmed (1 detector triggered) or Confirmed (2 detectors triggered) at which time the Police are alerted.

With this point in mind, it is important that the alarm is designed correctly to ensure that should a burglary occur the alarm will trigger 2 separate zones quickly before the intruder can get to far into the property.

It is important that the monitoring centre is recognised by the Police.

A unique reference number (URN) – which identified the premises – must be obtained by the Installing Company from the Police, when the system is installed.

To get this number, the installer and the monitoring centre must be registered with a certification body – such as the NSI

Monitored systems do not guarantee a Police response.

If it is reasonably certain that someone has entered the premises, it will be flagged as a confirmed activation. However, if a system has three false alarms in a year – four in Scotland – the URN will be revoked by the Police.

To be reconnected, evidence that the problem has been resolved must be provided to the Police within three months.

Types of Monitored System

Digital Communicator

This is the most common method of signalling at this time, and communicates with the Alarm Receiving Centre (ARC) via the properties telephone line, operational costs are low, but if installed incorrectly or where the properties incoming phone line can be easily compromised this method of monitoring will be made ineffective if the phone line is cut or disabled.

DualCom Dual Signalling

The DualCom GradeShift range offers a single piece of hardware for every grade of risk with interchangeable EN Grades.

Single path options G2r and G3r utilise all mobile networks via their WorldSIM to signal an alarm and are the ideal solution where there is no telephone line available.

Dual path options G2, G3 and G4 utilise multiple signalling paths via their WorldSIM & the properties landline to signal an alarm and have been designed with the lowest to highest risk premises in mind.

You simply pick the grade required.

DualCom is trusted to protect hundreds of thousands of premises throughout Europe including many major retail brands.

Key benefits and features:

  • Multiple signalling paths on board – GPRS, LAN/IP and telephone
  • Detects signalling path failure in seconds (line cut, GSM blocking, network failures)
  • Dual signalling is preferred by insurance companies and the Police
  • GradeShift enables remote up/down grade for change in insurance specification
  • EN Grade 2/DP1 dual path signalling service
  • Polling via Gemini every hour
  • Upgrade to GradeShift UDL available
  • Multi-network WorldSIM as standard for increased reliability

DualCom DigiAir

The DualCom DigiAir utilises all mobile networks via the DualCom WorldSIM instead of a telephone line to signal an alarm from the protected premises to the Alarm Receiving Centre (ARC).

It is designed for low to medium risk premises and is an ideal upgrade for wired digital communicators as it eliminates call costs and phone charges.

DigiAir is small enough to fit into any existing or legacy control panels.

It can be supplied complete with a Compact Power Supply for installations where the control panel is unable to consistently provide 12v DC and provides a more aesthetically pleasing finish.

DigiAir is also unaffected by Next Generation Networks (NGNs).

Like all CSL products, DigiAir is supported by the Gemini Platform, a Critical Connectivity platform responsible for the integrity of hundreds of thousands of premises throughout Europe.

Key benefits and features:

  • Eliminates call costs and phone Charges
  • WorldSIM as standard to increase reliability and reduce false alarms
