Stewbow Posted July 3, 2007 Share Posted July 3, 2007 When you said you moved the end of line unit from zone 4 to zone 3, was that with the circuit cables removed, with the end of line unit connected direct into the panel? Link to comment Share on other sites More sharing options...
whizzkid Posted July 3, 2007 Author Share Posted July 3, 2007 zone 3 had about 4 detectors and 4 call points wired with an eol reistor and was in fault zone 4 just had an eol resistor moved the resistor from 4 to 3 moved detecotrs + cp's and eol from 3 to 4 zone 4 works fine now zone 3 still in fault Link to comment Share on other sites More sharing options...

sparky999 Posted July 3, 2007 Share Posted July 3, 2007 It sounds like the lightning has blown the fault monitoring it is a common problem after a strike. New panel needed now Pete Peter Robinson Freelance M:07889038650 Link to comment Share on other sites More sharing options...

Guest G.J.M Posted July 3, 2007 Share Posted July 3, 2007 Whizzkid Just to be a bit boring but from your other posts,you are clearly no fire engineer,so you are leaving yourself wide open if you start mucking about with one as a favour to someone. Do yourself a favour and stick your 12 zone into your house and play about with it to your hearts content. You can only burn your own house down then if it does not work.

Guest anguscanplay Posted July 3, 2007 Share Posted July 3, 2007 can anyone do fire alarms then or do you need some minimum competance certificate - i mean because its life and death stuff Link to comment Share on other sites More sharing options...
integrafire Posted July 4, 2007 Share Posted July 4, 2007 Thats a good question. I have worked on fire systems, competently, for 10 years now and do not have a piece of paper to say i can. I haven't even done BS or BAFE courses. I do not work for myself but have in the past. It would be interesting if someone could diffinitively answer this one.

Chorlton Posted July 4, 2007 Share Posted July 4, 2007 BS5839 Section 1, 3.11 states- Competent person: Person with the necessary training and experience, and with access to the requisite tools, equipment and information, and capable of carrying out a defined task. BS5839 Section 6, 45.1 states- Inspection and servicing It is essential that the system is subject to periodic inspection and servicing so that unrevealed faults are identified, preventive measures can be taken to ensure the continued reliability of the system, false alarm problems are identified and suitably addressed, and that the user is made aware of any changes to the building that affect the protection afforded by the system. Periodic inspection and servicing needs to be carried out by a competent person with specialist knowledge of fire detection and alarm systems, including knowledge of the causes of false alarms, sufficient information regarding the system, and adequate access to spares. This will normally be an outside fire alarm servicing organization; care needs to be taken to ensure that, if, for example, in-house employees are used for this task, they have equivalent competence to the technicians of a typical fire alarm servicing organization. Competence of a fire alarm servicing organization can be assured by the use of organizations that are third-party certificated, by a UKAS-certificated certification body, to carry out inspection and servicing of fire alarm systems. Hope that's of some help in clarifying the matter. C. Link to comment Share on other sites More sharing options...
Guest G.J.M Posted July 4, 2007 Share Posted July 4, 2007 and within that 3rd party accredited company,the individual engineer needs to have have proof of competance for each section of fire systems they do. i.e design certificates for designers etc. They don't all come under the one big company umbrella (in theory) Link to comment Share on other sites More sharing options...
