I have heard from several installers  in the UK that the EN50131 or PD6662 requires a keyfob to be used to set and unset the alarm system, and that Comfort thus in unable to comply to the regulations.

This has never made any sense at all to me for obvious reasons. Does anyone honestly believe that this is a more secure method than alternatives?

Cytech has declared that Comfort does comply to EN50131 and PD6662. Could we have made such an error in missing out a key requirement like this?

We have re-read through all the  regulations to find the exact clauses which mandate the use of keyfobs. After this search we conclude that there is NO such requirement in either EN50131 and PD6662
There is NO mention of such a requiremnent at all. Please enlighten us if anyone can find otherwise


In DD243:2004, "Installation and Configuration of Intruder Alarm Systems Designed to Generate confirmed Alarm Conditions - Code Practice"
Section 6.3 states that the Means of Completion of setting should be one of the following;
  1. Shunt Lock fitted to Final Exit Door
  2. Push Button switch fitted to final exit door
  3. Door contact fitted to Final Exit Door
  4. PACE ie Portable Alarm Control Equipment, ie keyfob
(1) can be installed easily and connected to a Comfort zone to arm and disarm
(2) is achieved using Exit Terminator on a zone or Door station
(3) is Final Door arm

A Keyfob is only one of the 4 allowed options, and not mandatory

The misconception that a keyfob is a requirement must have been a misunderstanding or misinterpretation of the regulation which has been spread through the industry, and  I believe is causing great damage to the industry.
