Long Range (900 metre) Wireless 'S' Range Siren & Flashing Strobe System, supplied with:

  • 1 x Wireless Adjustable Siren with Flashing Blue Strobe Light.

They can be used in many applications including:

  • Wireless Safety Alarms.

The transmission range from the Wireless Transmitter to the Wireless Siren assembly is an impressive 900 metres (line of sight) which equates to around 400 - 600 metres in most applications, this can be at least doubled by adding the Signal Repeaters (004-2910).

  • Warehouses.
  • Schools.
  • Factories.
  • Farms & Rural Businesses.
  • Large Homes.
  • External Home Offices.
  • Workshops.

Wireless Siren:

The unique Built in Siren has 32 available Tones together with Volume Control (zero to 106 Decibel) allowing you to utilize the Control Box for your individual requirements. 

It is powered by a plug in transformer, which can be connected into a fused spur (recommended), we also offer the option of including a Back Up Power Supply for applications wanting to ensure the system works throughout a Power Cut.

How it Works:

The Heavy Duty Push Button (with 'Please Ring' etched onto it) is connected to a Long Range Battery Transmitter (fitted inside a easy to mount weatherproof box) by 3 metres of bell cable (which can be shortened or lengthen upon request).

The Push Button would be mounted onto the most appropriate location and the transmitter box would be located into the lost suitable location for wireless transmission (this could be simply on the back of a post or just inside a factory wall).

The Wireless Siren assembly is powered by a plug in Transformer and is fully weatherproof therefore can be fitted in indoor and outdoor locations, additional Wireless Sirens can be added to any system. 

When the Push Button is pressed, the Receiver will activate the Siren & Flashing Strobe Light, the standard duration options for the Siren activations are from 10 - 60 seconds or 5 minutes, for Panic Alarm applications we can supply a Latching Siren Assembly.

Installation Guide:

These Siren Systems are very Easy to Install, the basic process would be:

  1. Mount the H/D Push Button.
  2. Mount the Battery Transmitter & Box (4 x Screws).
  3. You may need to Remove the Cable between the Push Button & Transmitter Box to guide it through a hole in a Wall or Post (the cable can be lengthened or shortened to suit the installation).
  4. Choose & Adjust the Siren Volume & Sound settings (simple settings on the back of the siren).
  5. Mount the Siren Assembly (4-screws).
  6. Connect the Plug in Transformer into a standard 3-pin wall socket.

Many different accessories can be added to this Warehouse Bell System to suit most commercial applications, these include:
