Alarming

In which there is a flood, and the flood sirens stay silent as per specification


A few months back now, the Local Council decided to spend lots and lots of money on flood warning. They picked the most advanced flood warning system they could find, and erected enormous, giant-scale towers around the town, with large banks of speakers on top. They published maps of the town, with circles spattered over them, looking rather like those 1980s maps of nuclear blast radius,* so everyone knew which areas would be able to hear the flood sirens.

And now, with the worst rainfall for years, and roads closed or barely passable all over town, what have the flood sirens done? Absolutely bugger all, of course. Because that’s not the sort of flood they’re designed for. They’re to warn us against floods from the river defences failing, or the New Haven** bursting its banks. Neither have happened, although the New Haven looked to be within a few inches of a breach yesterday. Instead, we have flooding here because the Council don’t bother cleaning the drains out, so all the rainwater puddles on the roads.

* Talking of nuclear blast radius, who was the “psychic” who “predicted” that Hull would be destroyed by a nuclear attack in 1981? I really must look him up some time.

** It’s the “New” bit of the sluggish stream running through town, because it was cut in the sixteenth century.

Security (part two)

In which a contractor doesn’t do the job properly


So, as I explained yesterday, the security contractor at the office has saddled us with three “incompatible” security systems, two of which probably are compatible after all, it’s just that he doesn’t know how to get them to work together. We complained to the office manager about it. “Well, if that’s what the contractor said, that’s what’s going to happen.”

The next day, our boss comes through to visit. “What’s this about us needing three different tags for the alarms?”

We told him what we’d been told.

“It’s a bloody stupid idea. I thought they were all going to work together.” Yes, so did we. “I don’t want to have to carry three tags on my keyring.” And he wanders off, grumbling about it.

The following day, we notice the Managing Director stalking about in our part of the building, looking at the security gadgets and making “hmmm…” noises. The office manager is following him around, trying to explain how wonderful these expensive systems we’ve commissioned are.

“…you’ll have one tag for these doors, one tag for the outside doors and gates, one tag for…”

“Why do we need three different tags for everything? Why can’t we just have one?”

“The contractor says that they won’t…”

“Well, I thought we were just going to have one tag that would do everything. I don’t want…”

I tuned out, but it was clear the way the conversation was going. What makes me sigh isn’t that we always prefer contractors who have worked for us before, even when their track record is hardly promising.* It’s that the management should have spotted this coming. The contractor did give the office manager a nice thick specifications document – did the manager bother to read it at all? Didn’t he bother to ask questions about the vague parts?

* This isn’t the first time the security contractor has fitted something and then not set it up properly, because although he’s agreed to fit the system we wanted he’s not willing to learn how to configure it.

Security

In which we debate incompatibility


As part of all the building work that’s been going on at the office, we’ve been getting the security systems upgraded. A new alarm system, new motorised front gates,* and new electronic locks on most of the internal doors. All to be worked by RFID tags, kept on our keyrings and carried round all the time.

Now, being logical and sensible, we assumed that the company had specified either a single system, or compatible systems, so that we could use one single tag to unlock everything. And, as the contractor** started to install the hardware, we spotted that all the sensors we could see came from the same manufacturer. Very sensible.

We each get a tag the other week, and start using it to open and shut the front gates. Three days ago, the contractor pops his head round the door to say he’ll be issuing us with the rest of the tags, the ones for the indoor locks, soon.

“The rest of the tags? We’ve already got one.”

Apparently, we need separate ones for the outdoor locks, the indoor locks, and the alarm system itself. Because “the systems are from different manufacturers.”

“But they’re not from the same manufacturers! We’ve seen them, and they’re identical! If you hold an outdoor tag up to an indoor sensor, it recognises it!”

“No it doesn’t.”

I held my “outdoor tag” up to the newly-installed sensor by the office door. It bleeped, and flashed a little green light at me.

“Well, I can try to set it up so that that tag unlocks this door,” the contractor said. “But it won’t work.”

(to be continued, otherwise this post would get a bit long)

* Which is a Good Thing, because guess who’s job it is to unlock and open the old front gates every morning.

** Our usual security contractor, a friendly chap, who is very anal about making sure his cabling is put in and terminated neatly, but isn’t very good at setting up the security systems themselves properly.
