Every month we seem to get a challenge and this month has been no exception; a public building with a ten year old Hybrid Fire Alarm.
It’s clear this has been problematic for quite some time; the radio detection dropping in and out over the last few months. The question everyone asked was “why would you install half cabled, half radio?”. The more probable explanation was the complete lack of any cable route. This is the type of building where you can’t even get a phone signal 10 metres in.
Two weeks ago we sent a team of six to site with six MEWPS working twelve hour nights. The job sheet read;
- Install a new containment system to connect all the radio detector positions.
- Install the new panel.
- Commission the new detection to replace the radio.
- When complete change the system over loop by loop.
Two weeks on after the installation of 230 x 3.6 metre lengths of 25 millimeter conduit, 2500 metres of cable and installing 240 devices onto the new panel, it’s done.
We’re back on site tonight for a full test and certification later this week. You sometimes have to sit back and look at what out lads can do and realise they’re worth every penny.
Next months challenges are being planned now. Hopefully they’ll all be as successful as this monster.
