The last few years have seen a massive move towards Smart Alarms and in particular, the Ajax System which has taken the market by storm, our best seller. Tap on the link below to see more on the Ajax system. Smart alarms allow the user to remain in full control of their own systems and are proving to be serious game changers. We are keeping our eye on Smart Alarm market as it develops so subscribe to our newsletter and stay updated. 

The design of alarm systems is of integral importance for its effectiveness in detecting real threats while avoiding false alarms. The same can be said for the selection of devices for specific requirements. Incorrectly installed detectors could result in endless false alarms or a false sense of security.

Designing an Alarm System

Indoor Alarms:

One thing to remember with indoor home alarms is that sleeping areas are disarmed at night time. Therefore, any access areas leading to the bedrooms / sleeping areas must be protected with motion sensors and optional door contacts. Door contacts are not always required if the same rooms are protected with motion detectors.

The most important indoor areas to protect are: Main bedroom, passage/s, TV lounge, Study and other rooms that store valuables as well as garages, store rooms and outbuildings. These days children’s bedrooms do contact valuable items such as TV sets, laptops / PC’s, gaming consoles etc so these rooms should also be protected for when not at home.

For the office environment, door contacts should be installed on all out-leading doors and motion sensors installed in offices with windows as well as areas those that contain items of value. Passageways and open areas should also be protected as well as server rooms or similar

Outdoor Alarms:

We are most vulnerable in the early evenings and mornings when our indoor alarm system is disarmed allowing us free movement indoors. We are also completely oblivious to any outdoor activity while relaxing, cooking, watching TV or getting kids ready for bed or school. Outdoor motion sensors, if installed correctly, essentially create a safe zone around the house protecting our doors, windows and vulnerable areas externally. This prevents intruders / home invaders from getting close to the house or peering through windows to gather intel to plan their point of entry. Outdoor motion detectors also offer us great peace of mind while sleeping, and allowing us enough time to react to an alarm activation.

Alarm Partitions:

Certain alarm systems allow us to create partitions that allow us to independently arm e.g. indoors and outdoors or cottages etc. Smart Alarms are very strong in this area with Ajax allowing up to 25 groups / partitions which are independently are armed at the tap of a finger.
