lowlofe Posted March 20, 2009 Posted March 20, 2009 Hi there just moving into a old office building (1830s stone building) and its being turned back into a house, it has just had a brand new fire alarm fitted but the other day i had to drop a apollo detector to get a bit of plasterboard up and the panel didnt report a fault, this is a conventional system btw, i looked into this further and the system will report a fault if you remove a detector, but if you take out a sounder (base sounders in all the rooms) it has no problem, i have bell tested and they all work but it just seems to think everything is fine with no end of line, then i ripped up the floor in the room above and the sounder cable goes into a steel box marked "FIRE ALARM SOUNDER" where it is jointed with the base sounder its over then the cable carrys on to the next sounder, so each detector and sounder has 3 cables etc is there any problems with this style of system, or should there be no joints i give credit to whoever installed the system because they have really put the effort in and have made sure you cant see any fire cables apart from the ones in the basement and comms room, but i am concerned about all the joints regs alex

MatonTE1 Posted March 20, 2009 Posted March 20, 2009 Sounds a right mess if you ask me and that it's been installed by someone who can do a neat electrical install,"does fire alarms" and will wire in your cooker while they're there. The panel must report a fault if (i) a detector is removed,(ii) a sounder base is removed,(iii) there is an open circuit etc. etc.etc...
A-G Posted March 20, 2009 Posted March 20, 2009 Ask to see the certificates of design, installation, commissioning .... the zone diagrams ... the log book. . . . PM me for access to the SSAIB members discussion area.

In fact,if they wanted sounder bases why didn't they use the standard issue "fire alarm in a box" two wire system (we know who I mean) or an Apollo/Fulleon based solution?
leesutton Posted March 20, 2009 Posted March 20, 2009 sounds to me like they have spurred of the detectors, you need to spend time on testing the cables and work out what goes where....

lowlofe Posted March 20, 2009 Author Posted March 20, 2009 All the detectors are wired in correctly, but the sounders are spured off one wire with a end of line in the last sounder (which is in a conventional sounder in the attic) no log book and no certificates and i have no idea who makes the panel, regs alex

unimatrix1066 Posted March 22, 2009 Posted March 22, 2009 usually when this happens someone has fitted a panel that takes either aeol units or resistors(cel precept,ctec etc) , were diode bases are fitted an aeol is required but if its an old system ,new panel non diode bases would be present. I see this all to common on some sites were a sparks or so called engineer has commissioned it. What make of panel is it?
