AdamG Posted January 10, 2017 Author Share Posted January 10, 2017 Regardless of what fire panel is in, it would still need a change in sensitivity from where the bulilding is physically open to closed. If it were my design I would have used a syncro with apollo discovery heads.... it's not.... and the arguably incorrectly specified system is about 3months old. Ripping it out isn't an option. Smoke & heat to heat only when unoccupied with be fine based on its designation. *** Does anybody know how long a Honeywell rio will hold it's outputs if it loses its data connection to the panel? Fike have given the nod for the Rio pcb to be installed in the twinflex panel can you see any problems with this if I tamper the front and back of the twinflex panel? Thanks for all your input Quote Link to comment Share on other sites More sharing options...
andy™ Posted January 10, 2017 Share Posted January 10, 2017 along similar lines, my unit has a mixture of heat & smoke detectors all NC. during the day its a somewhat hostile environment (lots of dust, welding etc). i simply have an output from the alarm to trigger a 4 pole relay where each pole is linked to each NC on the detectors so if they detect smoke and open the contacts, they are still being closed by the relay. but this im my own building that is not open to public and doesnt require a fire alarm anyway so i dont have any fire alarm regs etc to worry about Quote Link to comment Share on other sites More sharing options...

Over the years I've bodged loads of stuff together to get clients out of a fix, In the long term your no better thought of, in fact your more likely to be seen as awkward for saying no when the ideas get too dangerous & dumb If a 3 month old system is notorious for FA it must be completely unfit for purpose, I'm guessing vesda is what the building should have. 1 Quote Mr Veritas God Link to comment Share on other sites More sharing options...
james.wilson Posted January 10, 2017 Share Posted January 10, 2017 to answer the Rio question on panel lost (I'm assuming self powered Rio) then fairly immediate assuming they are inverted Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
