Re: COMM failed status of Fire Alarm 8000 series

["Petem" <petem001@xxxxxxxxx>]

if your customer really need the function,the fact of wear on a relay is
very acceptable,but is there a way to us a zone that will not make the panel
go into alarm or trouble(like a technical zone),and the zone would be
trigged by a timer relay and this will work for years,I use that as a way to
monitor some communication status in a kantech access control system,and the
relay been working for the last 6 year
