Burglar Alarm Bell Boxes & Sirens are a key part of any intruder alarm system, providing an immediate audible and visual warning when an alarm is triggered. This collection includes both internal and external alarm sounders designed to deter intruders and alert occupants or neighbours. Suitable for residential and light commercial installations, these products are a practical choice for new systems or replacements.

The range covers external bell boxes, alarm sirens and internal sounders in various styles and formats. These products are commonly used by trade electricians, security installers and informed DIYers working on wired or wireless alarm systems. Whether you are fitting out a new property or updating an older system, reliable alarm notification is essential.

Bell boxes and sirens are typically installed on exterior walls, hallways or key access points where sound and visibility are most effective. External sirens act as a strong deterrent, while internal alarm sounders ensure anyone inside the premises is immediately aware of a breach. They are suitable for houses, flats, small offices, shops and outbuildings.

When choosing a burglar alarm bell box, it is worth considering whether you need an internal or external unit, the sound output level, and how it will be powered. You should also check the fixing location, environmental exposure for outdoor units, and compatibility with your existing alarm control panel.

All products in this collection are selected for use within standard intruder alarm setups. Always refer to the individual product specifications to confirm suitability for your system before installation. If you are upgrading or replacing an existing siren, matching the connection type and power requirements can help avoid unnecessary changes.
