Wire-Free Radio Burglar Alarm Technology
Radio technology for burglar alarm systems has speedily advanced in recent years. Until now, radio burglar alarms (wire-free burglar alarms) were considered by most major security installers to be unstable. However, all this has changed with the new technology incorporated in the Honeywell Domonial Wireless Security System.
Honeywell are recognised as world-wide leaders in the manufacture of security products and their Domonial Wireless Security System is the very best in the market. We know, because we've tested them all!
Wireless Alarms UK specialise in radio alarm technology. We only sell the Honeywell Domonial alarm control panels, alarm sensors and other alarm devices for a good reason.
To be effective, an intruder alarm system must be infallible. It must be capable of reliably detecting intruders and should not false alarm.
...So Why Is The Domonial So Much Better Than The Rest?
Whereas many other wireless radio alarm systems currently on the market use simplex radio communication - last generation technology - the Domonial uses Honeywell's own Duplex Alpha Radio protocol which is key to the Domonial’s stability.
The Honeywell Duplex Alpha Radio protocol is a state-of-the-art, two-way radio communication system that delivers real security. It makes the Domonial, without question, the most advanced, stable and secure two-way radio panel available on the market today.
Not only does the Domonial use its own unique protocol, it also uses 868MHz for its communication, a frequency that is reserved purely for the security industry. Many other wire-free alarm systems still use the old 433Mhz frequency. This frequency is shared by numerous other devices - such as garage door openers, car alarms, radio hobby projects, etc - and has a real potential to overload and cause a security system to false alarm.
Radio signals can be affected by all sorts of abnormalities. The Honeywell Duplex Alpha Radio protocol uses six channels within the 868MHz frequency to send and receive different kinds of information. This makes it both exceptionally stable and extremely secure.
The panels of most other radio burglar alarm systems only have one chance to receive a message sent from a detection device, and if interference occurred whilst an alarm signal is being transmitted, it is highly likely that the alarm system would not activate. Nor are these radio systems smart enough to recognise that they have missed some communication. But the Domonial's bi-directional signalling ensures that the message always gets through.
It works by the Domonial transmitter sending a message on one channel, then its integral receiver switches into listen mode. If it doesn't get an acknowledgement message from the radio receiver within a predetermined time, it repeats the whole procedure until it does.
The Domonial fully conforms to PD6662:2004, DD243:2004 and EN50131 Grade 2 specifications.
PD6662:2004 is the current British Standard for burglar alarms. It almost completely superseded BS4737 in October 2005.
DD243:2004 is the British Standard for Installation and Configuration of Intruder Alarm Systems Designed to Generate Confirmed Alarm Conditions.
EN50131 is the current European Systems Standard. The security and insurance industries often use the term 'Risk Assessment' for EN 50131-1 (or the British equivalent PD6662), which lays down a structured Risk Assessment procedure for designers of intruder alarm systems.
