Audible Intruder alarms for home and business

Home » Burglar Alarms » Audible Alarms

A burglar alarm system is a worthwhile investment for protecting your home or business premises. Studies show you are far less likely to be the victim of an intruder if you have a well-maintained intruder alarm installation.

Audible intruder alarms are ones that sound a bell or siren when activated. They can also activate security lights and deliver an alert to a smartphone, tablet or desktop computer.

The primary purpose of an audible intruder alarm is to disturb the would-be burglar and to alert neighbours or anyone passing by. Surveys suggest that intruder alarms are ineffective as alarm bells can be ignored or 'written off' as false alarms.

However, audible alarms can be useful in places like Neighbourhood Watch areas where there is usually a more security-conscious ethos. They can also work as a visual deterrent prompting would-be burglars to look elsewhere.

The drawbacks of not having any burglar alarm system installed can be dramatic, as crime figures show:

  • Properties with no security system in place are five times more likely to suffer a burglary.
  • Estimates say 93% of burglars steer clear of homes with visible intruder alarms.
  • Around 74% of burglary attempts are abandoned when an intruder alarm goes off.

Audible burglar alarm installations

An intruder alarm system uses electronic components to alert the user to any interloper. Sensors are usually installed at vulnerable points and connect to a central control hub via low-voltage wiring or a wireless link. Sensors can be of various types. Some can 'sense' the opening of a door or window while others 'detect' movement with passive infrared PIR. Systems can also alert to fire, gas, flood or carbon monoxide.

The systems supplied by Crown Securities UK are installed by experienced engineers with extensive knowledge of home security systems. Each network is fully configured to the individual customer's needs. All our installations come with a guarantee.

Wireless security systems


Wireless burglar alarm systems are growing in popularity; mainly a result of recent improvements in the reliability and sensitivity of electronic components. A wireless alarm system takes less time to install, requires no drilling or wiring, and upgraded or extended whenever the need arises.

Wireless alert systems are also portable so they can move with you to a new property. Also, as there are no cables to be cut or damaged, a wireless response alert is often much easier to maintain.

Wired security alarm systems

Wired alarm system

Wired alarm systems use alarm cable wiring to connect sensors to the control panel. Wires are usually hidden by passing cables through existing wall cavities or local loft spaces. When cables cannot be concealed, trunking is used to make them as discrete as possible.

Hybrid wired/wireless security systems

Hybrid alarm systems combine the aspects of wireless and hard-wired sensors. Hybrid set-ups offer a robust system with opportunities for expansion, giving customers the best of both worlds. Audible burglar alarm installations can also be wireless.
