AJAX Wireless Outdoor Siren, Black and White

The AJAX Wireless Outdoor Siren is a wireless alarm siren made for outdoor use. It belongs to the AJAX family of alarm components, which are designed to work together as one wireless security system. This version comes in a black and white colour scheme, chosen to suit the exterior of a wide range of buildings. It is sold as a single product in our catalogue under article number A-STREETSIREN(B&W).
What the siren does
An outdoor siren is the part of an alarm system that makes the alarm heard and seen from outside the premises. When the system is triggered, the siren sounds an audible warning. This can alert neighbours, passers-by and anyone on the property, and it can discourage intruders by signalling that the premises are protected. The siren is a visible element of a security installation, so its appearance also matters to many customers.
Key features
- Wireless design, so no mains cabling is needed to run to the unit from the control equipment
- Built for outdoor installation
- Black and white colour version to match the exterior of the building
- Part of the AJAX wireless alarm range
- Suitable for upgrading an existing installation or building a new one
Installation considerations
Choose a mounting position that is high enough to carry the sound well and out of easy reach for vandals. Keep the siren away from direct obstacles that could block the sound. Because the product is wireless, placement is flexible, but the signal between the siren and the rest of the system should be tested after installation. Follow the manufacturer’s guidance for mounting, power and pairing with the alarm system, and check the supplied documentation for the exact requirements.
Typical uses
- Homes with an existing AJAX alarm system that need an exterior warning device
- Shops, offices and small businesses requiring a visible and audible outdoor alarm
- Properties where running cables for a wired siren would be difficult or costly
- Extending an alarm system to outbuildings, garages or boundary areas
- Replacing an older outdoor siren with a wireless model in a neutral colour
Why choose a wireless outdoor siren
Wireless sirens reduce the amount of drilling and cable work needed during installation. They can be moved or added later with less disruption than wired devices. For many buyers, this flexibility is the main reason to choose a wireless model. The black and white finish also gives the siren a discreet appearance on most facades, which suits customers who want security equipment that does not stand out.
Before you buy
Confirm that the siren fits your existing or planned AJAX system and that you have the other components you need. Read the manufacturer’s documentation for technical specifications, power requirements, mounting instructions and any terms of use. If you are unsure which parts work together, ask a qualified installer before ordering.
This siren is a sensible choice for anyone who wants a clear outdoor warning from a wireless alarm system, in a colour that suits the look of the building.
