Separate visit for aspirator pm?
#1
All,
    We have a new work scheduler (which will fix all problems and make everything better!!) And someone has come up with an idea that we should have aspirators set up as a separate pm relative to the main fire alarm, even trying to say 'this is a requirement' although they can't quote who or what requires it...

Thoughts?

Previously we've split up  visits via engineer preference on an engineer created site specific excel spreadsheet eg visit 1 = mcps and sounders, 2 = heats and relays/shutdowns, 3 = smokes, 4 = aspirators.

Have i missed something? Is every other company doing aspirators as a separate visit?

An aspirator is a detector but has a PSU. I’ve always treated as part of the main service regime and ensures the PSU gets checked at least 6 monthly.

An asd is just a detector and a psu. The only time I've ever seen them treated as a separate visit is if a lifter is required.

Every sampling point is treated as a detector, therefore every sampling point should be tested once per annum.

VESDA airflow should be checked on each visit & pipework inspected (every x6 months) as per their recommendations (https://www.firesense.nl/wp-content/uplo..._guide.pdf).


In reply to the OP, I don't understand why a company would want to maintain aspirators on a separate visit to the main FAS. Additional travel time, duplicated documentation etc will surely add additional unnecessary costs, unless these costs are being passed onto your client?

Unless it is purely due to 'normal' FAS technicians not being competent to work on aspirators.

It's not just service guys who are not competent to work on them....... there's a lot of commissioning guys who dont know how to set them up as well.

Have always said aspirators are easy...... if you know how..... but even easier to get wrong. 

Recently did a site with 5 VESDA just out of Warranty and none of them had been setup properly

It's very rare that I go to an asd that's been set up properly.
We took over a job that had had new pipe installed by electricians and commissioned by a big national. 
One of the pipes didn't have any sampling points. Not even in the end cap.
The solution appeared to be sightly loosening one of the joints. 
The other 4 on site had been set up for Auto fan speed (the default on Faast asds) and 2 had been set up to not auto reset alarms.
This place had weekly events where the asds always activated and a button on the panel was set to isolate the asds to allow this, but obviously putting them back on was hard considering there were 2 of them always in alarm and site had never been shown how to reset them.

Yep i don’t understand it either. I have tried to ask why they have been deeemed as separate with no good answer, maybe because it may require 2 men and a mewp which affects the schedule for the other visits...

Same service mate... only time there's something extra, as an additional service to add on, is if its an extinguishing system.
