Intruder Alarm

What the system is for

Break-ins go unnoticed until morning, and there is no immediate alert to occupants or responders.

An intruder alarm is about noticing entry at the moment it happens. The zones, the detection method and how the system is armed are agreed before equipment is selected.

• Detection at doors, windows and internal movement routes
• An audible warning at the premises when a protected zone is triggered
• Zone indication so the triggered area is identified
• Panic or emergency signalling where the equipment and site call for it
• Arming arrangements that suit occupancy patterns rather than fighting them

Typical premises

• Homes
• Shops
• Offices
• Apartments

What an intruder alarm usually includes

Alarm systems are built from a panel, detection devices and notification. How many of each depends on the layout and how the space is used.

• Control panel and keypad

  The centre of the system, installed in a protected position with a keypad where people enter.

• Motion detection

  Internal detectors covering movement routes such as hallways, landings and open areas.

• Door and window devices

  Contacts and perimeter detection at the openings that matter on your layout.

• Sirens and notification

  Audible warning devices positioned so an activation is heard where it needs to be.

• Power and backup

  Standby power so the system keeps working through a mains failure.

Zone counts, notification options and any remote signalling features depend on the panel selected. We confirm what a specific system supports before quoting it.

System design considerations

• What is being protected

  A home, a shop floor and a stockroom need different detection. Listing the vulnerable areas comes first.

• Zoning

  Grouping detection into zones makes activations meaningful and allows part of a building to be armed while the rest is in use.

• Entry and exit routes

  The way people normally come and go decides where detection sits and how arming delays are set.

• Detector placement

  Heat sources, pets, curtains and glazing all affect where internal detection can sit without false activations.

• Arming and disarming

  The system has to fit daily routine — who arms it, when, and how a mistake is corrected.

• Notification

  Where the siren is heard, and who is expected to respond, is agreed rather than assumed.

• Panic and emergency signalling

  Where the equipment supports it, panic devices can be placed at tills, bedrooms or reception points.

• Power and continuity

  Backup power and sensible cable routing keep the system working when the supply is not.

• Working with other systems

  Alarms are often paired with cameras or an electric fence so an activation can be verified.
