Ajax Sirens

Ajax sirens sound the alarm and show the status of an Ajax security system with light and sound. 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. SmartBracket mounting panels, a spare Brandplate faceplate and a StreetSiren dummy housing are here too.

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

Should I choose a Jeweller or a Fibra Ajax siren?

Choose Jeweller for a wireless siren and Fibra where a cable can be run to the hub. Jeweller sirens such as the HomeSiren 176851.391.WH1 run on pre-installed batteries, while Fibra sirens are wired: a single Fibra line can take up to 10 Superior StreetSiren Plus Fibra sirens such as the 117727.268.WH1, with a wired communication range of up to 2,000m without line extenders.

Is there a Grade 3 Ajax siren?

Yes, the Superior G3 models are Grade 3. The Superior StreetSiren Plus G3 Jeweller 137749.308.WH1 is a wireless Grade 3 outdoor siren that connects to a hub or range extender at up to 3,000 m, and the 137750.308.BL1 is its black version. Indoors, the Superior HomeSiren G3 Jeweller 140411.11.WH1 connects at up to 3,500 m and its batteries last up to 2.5 years.

Can I put my company name on an Ajax siren?

Yes, on the StreetSiren DoubleDeck sirens, which take a Brandplate front panel for a logo, name, phone number or website. The StreetSiren S DoubleDeck 133226.61.WH1 and the StreetSiren DoubleDeck Jeweller 38180.61.WH1 carry one, as does the wired Superior StreetSiren DoubleDeck Fibra 143638.61.WH1, and spare AJAX-SS-DD-BRANDPLATE faceplates fit the DoubleDeck family.

What does the SmartBracket do on an Ajax siren?

It is the mounting panel that holds an Ajax siren on a wall, sold here as a spare or replacement. The 9678.07.BL and 9679.07.WH suit the StreetSiren and let it be fitted without opening the enclosure, with a securing screw against removal. The 9566.11.BL and 9567.11.WH suit the HomeSiren and keep its tamper detection working through perforated tamper sections.
