any Chubb engineers here?

[wjwren]

Doing a job in an office and accidentally drilled through some fire cable for the automatic doors. Office have called Chubb out to see how renewing the cable which is about 20m back to the control box as they cant join old and new up. Any idea on their hourly rate?

[dav123a]

Why can't they join it ? Is it Pyro ? I would hazard a guess at non contract rates £60 an hour.

Cables can be jointed but the connections must be accessible. The cable is most likely MICC (Pyro) or modern soft shell. There is no reason why the two cannot be jointed.

Chubb fire alarm systems can be difficult in that they are mostly 'closed protocol', meaning commissioning has to be done by one of their technicians, but if it is only cable damage, it may be possible for any competent fire alarm contractor to repair the damage without the need to piss around with the panel too much.

Do you have a fire alarm contractor for your regular maintenance?

Apparently its pyro presently but will be replaced with Fire proof' cable that back to the circuit breaker.

The doors won't be directly powered from the fire alarm, they will either have a interface near by or a relay in the fire panel that just switches a contact within the door controls unit or knocks off the power if it's a door hold open. This will be a normally closed going open contact and could be in any cable really as it's a fail safe way of doing it.

(Unless you have gone though the mains, I'm which case any electrician could replace it)

It wouldn't require chubb to replace it either, anyone can run the cable from the door contact, find the fire interface and open it to replace the cable. Most chubb fire panels are just a rebranded morley fire panel, which are open protocol. Since your replacing like for like you wouldn't need a code.

More than likey it will be apollo devices, which are simple to use and have a wiring list on the front of them.

What sort of doors are they?

I work for another Secuity and fire company and our call out is £75 then £60 a hour labour. Chubb are more and won't even come out untill you provide a credit card details. ( work with a ex chubb engineer)

Where are you located?

We use Chubb as a subcontractor to us quite often for new builds, refurbs etc. They certainly aren't cheap! But as mentioned you've hopefully gone through the cable from interface unit to the door which will make things a bit easier to replace and hopefully cheaper.

Out of intrest why do you use chubb? Most places have good in dependant companies that would do the work cheaper and quite likely better, chubb work on commission so it's done as quick as possible.

It will be a ancillary cable if you had gone though the loop the panel would be going mad with beeping for missing devices and open Ciricits or shorts

from what i understand its the red pyro cable i have gone through that controls the magnetic doors and also a white normal 3 core cable for the "exit" sign. Im still waiting for chubb to get back with a quote.

The exit sign is just standard mains cable, simple enough to replace back to it's test key which will be near by they tend to just be on the lighting circit.

And as I thought it's just the control cable from the interface to the doors. No more than half a days work, about £350 I bet

It most likely is, but it may not be. It could be Pyro, and it could be from a central battery unit or be part of an addressable system. Any competent electrical contractor should be able to sort it though.
