As a proactive engineer, I am constantly looking to understand why I am carrying out the works that I am, before I carry them out. So that any repairs I make are not short-term, but long-lasting fixes.
A few weeks ago, I visited the New Deanery in Braintree while my father was a patient there. Walking around the building my attention was caught by a few of the fire Dorgards giving off warning tones. Similar to the one in the image below.
I mentioned it to a member of staff, pointing out you may want to get them checked. The member of staff replied, ‘oh they need the batteries changing’.
Knowing the pattern difference between the warning tones by ear, I knew it was actually a plunger fault with the dorguard. As you look at the floor you can see arc marks where the door has opened & closed. These marks are caused by the door being dragged without the dorguard being released correctly. Occasionally these can be reset with no harm, but if they continue to be dragged, the dorguard is useless & requires replacing.
At my previous company, I attended a call out and was asked to change the batteries.
Another engineer had been 3 times in the past few months to replace the batteries in the same dorguard.
The client told to me about this, at which point, noticing the huge drag marks on the floor, I had to explain it wasn’t the batteries, but actually, a plunger fault & they would now need to buy a new one.
This was as a result of the user not knowing how to properly operate their system coupled with inept engineering practice. Both of which could be easily fixed and could save hundreds.
Training the users to correctly operate the Dorgard will have prolonged the life of the system as there will have been less damaging use.
Also, had the engineer known the difference before the unit was too far gone, it would have been a simple replacement, saving numerous unneccessary battery changes.
It wouldn’t have taken much for the engineer to look into the reason why he was returning to fix the same fault, but the easy option was to just do as he was told and not question anything.
Be proactive and get it fixed properly!
All the best,
