Intruder Alarms

Alarm Burglar (or intruder), fire, and safety alarms are electronic alarms designed to alert the user to a specific danger. Sensors are connected to a control unit via low-voltage wiring which is used to interact with a response device.

The most common security sensors are used to indicate the opening of a door or window or detect motion via passive infrared (PIR). New construction systems are predominately hardwired for economy.

Retrofit installations often use wireless systems for a faster installation. Most business systems are monitored 24hrs with police response. Some systems serve both fire and intrusion protection.

And, this is what the local police are saying:
"Alarm systems are a worthwhile investment in the protection of your business. Studies reveal that it is far less likely that you will become the victim of a burglary if you have a correctly fitted and well maintained burglar alarm".

Who takes notice of an alarm sounding?

He Does!Quite frankly, it doesn't really matter who takes notice of your alarm sounding as long as the intruder does, right?

The fact is; thieves do not hang around when an alarm is sounding. Why should they? They don't know who is responding to the alarm and they don't want to be caught. The likelihood is this won't be there first offence and the consequence of capture is likely to be a term in prison. Almost all business systems are monitored 24hrs and the police will have been notified and be on their way.

But don't take our word for it, this is what a convicted burglar said recently, when interviewed;
""I always missed places that I could see had an alarm installed, there's no point in risking getting caught, there's plenty of other places without one. I think it's funny when people put dummy box's up, it's so obvious." Peter from Stoke-on-Trent.

Our advice

  • Whichever system you choose, always ensure there is a battery back-up for hard-wired and monitoring systems so the call centre can still be contacted even if the power lines are disconnected or there is a power cut.
  • If you want the police to respond to your alarm, it must conform to European Standard EN 50131. Wireless alarms must meet BS 6799 Class VI. Other systems have caused too many false alarms.
  • Fitting a 'Dummy Box' is false economy, as experienced burglars can tell the difference between a real and fake alarm.
  • Always ensure your alarm system is installed and maintained by a reputable security company who is accredited by the National Security Inspectorate (NSI) Gold standard. Accredited companies are audited every six months by external NSI Technical and Quality Inspectors.

Types of alarm

Intruder warning

This could be an 'audible only' alarm that sounds when someone tries to either break in or cut the wiring.

Monitored alarms

These alert the alarm system installer. The company then rings your nominated key holder and then alerts the police who will attend.

Autodial systems

Will send a voice message to your mobile phone that alerts you to the fact that your alarm system has been triggered.

The most popular types of detector devices for your business

Infrared sensors

Infrared sensors

This type of protection is very efficient in covering large areas of your business such as offices, reeption areas, warehouses, etc. and will detect the movement of intruders or a rapid change in temperature that you may get when a window is opened or smashed and is usually positioned in particularly vulnerable areas.

They also allow you to isolate areas, such as those that you may use at night, for example, the production areas, whilst having the main offices and any sensitive or vulnerable areas alarmed.

Door and window contacts

Door and window contacts

These are small unobtrusive contacts that are placed on an opening window and frame and/or on an opening door and frame. When the system is 'set' a magnetic field runs between the two contacts and, if the protected window or door is opened the alarm system will sound. Entry and exit routes are programmed with sufficient delays to allow the alarm user time to 'set and 'unset' the alarm on exit and on entry.

Will buying an alarm system reduce my business insurance premium?

Yes. Major insurance companies are now giving good discounts to business's who have invested in an approved Intruder alarm system to protect there business contents. The main criteria is that they must be installed by an approved security company accredited to the National Security Inspectorate (NSI) National Alarm Council Of Security Systems (NACOSS) Standard.

Crimewatch Security Limited is an NSI NACOSS GOLD Accredited company which means we also hold the approved standard of Quality Assurance, ISO EN 9001/2.
