Police Response Intruder Alarms

Monitored 24 hours a day, 365 days a year

The inconvenience and stress of burglary can be overwhelming and very frustrating. Burglars cause physical and emotional damage, by taking both personal, sentimental possessions and essential equipment used to operate your business.

Many burglaries are opportunist crimes, with burglars selecting targets with the best opportunities and the fewest obstacles to detection. Although an effective alarm doesn't guarantee to prevent a break-in, statistically it is a very effective deterrent.

Before installation

Delta carries out a survey to assess:

  • How many sensors you need to protect your property
  • Where sensors should go
  • Location of security panel
  • Type of alarm (wired or wireless)
  • Level of monitoring you need.

Larger organisations and premises can link their alarm to their access control systems.

After installation

Our alarms are monitored 24 hours a day, 7 days a week, all year round. If your alarm goes off, our monitoring system gets an alert. We then contact the nominated keyholder. If you opt for police response monitoring, we also contact the police.
