Fire Panel showing 2 actuated zones?

[Redone]

When the fire alarm is triggered, the panel is showing two actuated fire zones, not heads, zones?  The staff say it's always done that???  Management say it's being dealt with.

This a care home where it will take upto 20 minutes to prep a service user to be moved and the stairs are not an option, so early intervention by the staff is a must.

I thought this was a fault with the call point wiring in to the panel, so tested another call point, again two different zones came up!

Should this problem not be highlighted during the periodic servicing?

What's causing this and how is it cured?

Assuming its an addressable panel, it sounds as though the devices (MCPs) have been assigned to more than one zone. Commissioning engineer should be able to sort it quickly.

It could have been done (wrongly) to make it easier to control any interfaces / IOs on site

On a conventional panel , the only time I had this is where the '0 'volt' is commoned up in the panel ie in a Ctec panel . There was a bad earth fault on one zone and this
was enough to pull in another zone.

On the addressable side I would agree with the last posted reply , somewhere in the programming a relay/interface has been zoned and you are getting another flag coming up,  when any possible cause and effect comes in. What make of panel is it , and protocol ?

In theory most (and this is a general statement) panels will only allow you to designate 1 zone per device on the general loop address feature , under text information .

possibly 2 conventional panels linked together,
e.g. fire in zone 1 shows fire in zone 1 plus fire in zone 8, where zone 8 is the other panel which is in turn activating this panel on a non latching zone.
You may find another panel on site doing the equal but opposite thing!

One panel on ground floor - FPP 145 CONTROL CENTRE marked to 5839, 1988, repeat panel on the 2nd floor.

Panel indicates zone with red indicator light, no text

Sounds like a 'badged up' panel , not familiar to me , however must be an older panel with this BS Markings. You may be unlucky say for instance its an old Photain Controls panel , they were bought out by Ziton , some years back . Any other info that might enlighten us to the make.

I'm visiting the site again on Friday, I'll see what I can find out.

How do find out the 'protocol'?

Thanks for everything so far.  Much appreciated.

[Graeme]

the protocol is what make of detectors etc the panel is using  i.e Apollo Series 65 for convention XP95 for addressable etc.

[Redone]

Cheers Graeme, will find out.

are the eol resistors installed out on the field or at the panel?

if the resistors are fitted at the panel, i reckon your cables might be mixed up - ie you've got the zone 1 +ve or -ve cable into zone 2, and vice versa

[monkeh]

failing that, take out all your zones and test each zone for fire using a 470/560 resistor at the panel (or by shorting the connections if the panel is s/c = fire.

that'll at least take a fault panel out of the equation. if the zones work then your problem is your zone cables crossed over out on the field

Smoke detectors are BRK 1800EC dated 1988.

[Graeme]

only know BRK form 240v smoke alarms. Sounds most like a conventional system so open/closed protocol is not likely to apply.
