The page holds indoor HomeSiren models, outdoor StreetSiren models with an LED frame, StreetSiren DoubleDeck sirens that carry a printable Brandplate, and Superior G3 sirens for Grade 3 sites, in wireless Jeweller and wired Fibra versions.

Choosing Ajax Sirens

Decide indoor or outdoor, then wireless Jeweller or wired Fibra, then grade and branding.

Indoor: HomeSiren

The HomeSiren Jeweller 176851.391.WH1 runs on pre-installed batteries for up to 5 years, has adjustable volume from 80 dB to 100 dB and an external LED connector, and reaches a hub or range extender at up to 2,000m. The Superior HomeSiren Fibra 143560.11.WH1 is a wired indoor siren with volume from 81 dB to 105 dB and alarm durations from 3 seconds to 3 minutes. For Grade 3 sites, the Superior HomeSiren G3 Jeweller 140411.11.WH1 connects at up to 3,500 m.

Outdoor: StreetSiren

The StreetSiren Fibra 44412.07.WH1 has an LED frame, adjustable volume from 85 to 113 dB at 1 m and an IP54 rating, and is powered from the Fibra bus with a pre-installed backup battery. A single Fibra line can take up to 10 Superior StreetSiren Plus Fibra sirens such as the 117727.268.WH1. The Superior StreetSiren Plus G3 Jeweller 137749.308.WH1 is a wireless Grade 3 outdoor siren whose pre-installed batteries last up to 10 years.

DoubleDeck and Brandplate

StreetSiren DoubleDeck sirens carry a Brandplate, a front panel on which a security or installation company can print its logo and contact details. The StreetSiren DoubleDeck Jeweller 38180.61.WH1 reaches up to 113 dB in an IP54 enclosure, and the Superior StreetSiren DoubleDeck Fibra 143638.61.WH1 is the wired version. Spare AJAX-SS-DD-BRANDPLATE faceplates fit the DoubleDeck family.

Mounting and spares

The SmartBracket 9678.07.BL mounts a StreetSiren without opening its housing and has a routed cable entry and a securing screw. The 9567.11.WH is the HomeSiren version, and its perforated sections trigger the siren tamper if it is removed. The 38182.65.WH1 dummy housing mimics a StreetSiren as a visual deterrent, with no electronics.

Frequently asked questions

What is an Ajax alarm siren?

An Ajax alarm siren is a sounder that joins an Ajax hub and sounds when the system detects an intrusion, alerting people nearby and deterring the intruder. Indoor HomeSiren models and outdoor StreetSiren models come in wireless Jeweller and wired Fibra versions. Volume and alarm length can be set in the Ajax app. The range here includes indoor and outdoor Ajax sirens.

What is an Ajax street siren?

An Ajax street siren is an outdoor sounder, known as StreetSiren, that pairs a loud piezo alarm with a bright LED frame for audible and visual warning. It is weather resistant for exposed walls and has tamper and anti-detach protection. Wireless versions usually run on pre-installed batteries, while wired Fibra versions take power from the system bus with a backup battery.

What battery does an Ajax indoor siren use?

A wireless Ajax indoor siren runs on pre-installed batteries, and some models use a pair of CR123A lithium cells. Battery life can stretch to several years, depending on settings such as volume and alarm length. The Ajax app shows battery level, so cells can be swapped before they run flat. Wired Fibra indoor sirens take power from the system line instead.

What is an Ajax double deck siren?

An Ajax double deck siren is an outdoor siren, known as StreetSiren DoubleDeck, with a Brandplate front panel that can carry an installer's logo and contact details. It sounds loudly and lights up on alarm, and the branded panel turns it into visible advertising for a security company. Spare Brandplate faceplates can be printed and swapped. The range here includes wireless and wired DoubleDeck versions.
