You are a teacher. Taught him not to ask a question as an instruction.

I don't think you need to worry about that really. Mains alarms on backup almost certainly pull no more power than battery alarms.

Mine will beep their "low battery" warning for about 15 minutes after both mains and battery have been disconnected, running off their PSU caps alone.

Cheers,

I know, but it was fun!

I was actually amazed to see that PP9s are still sold. And not as expensive as I thought.

[Max Quad]

You presume correctly.

[Brian Gaff]

Well its a bit ambiguous to my mind. Brian

[Brian Gaff]

So are these alarms interconnected on just their output, ie their triggering, or do they also all share a mains supply? Also of course do they have internal allarms so they can function as a stand alone unit, and is there protection for the battery in each alarm so its not running all the others if the residents nich the batteries as seems to happen in a block of flats near me.

[Brian Gaff]

That term is ambiguous, and can be viewed multiple ways, who thought that one up, Arfry Daley look alike?

I understood the question. ;>)

& anyway don't these mains ones beep when battery is low/not fitted (assuming circuit is powered)?? sure mine do and flash a red LED so you can tell which one is on it's way?

Yes.

The conversation went roughly like this "Did you connect the batteries to the smokes when you second fixed them?" "I do not know what you mean" "Which bit do you not understand" "All of it" "You do know that there are batteries in the smoke alarms don't you?" "Yes" "And you do know that when you buy the alarms they do not work because the batteries are not connected to the alarm?" "Yes" "So which bit of my question do you not understand?" "The connection bit" "Even though there is no power to the building will the alarms you fitted work?" "Yes" "Why?" "Because I put the battery in" "The battery was already inside the alarm, I am asking if you actually connected the battery to the smoke." "I am still not sure about the connection bit"

FFS and it carried on. And when you have two of them for a week it's no wonder you occasionally shout at them.

Finally we got there and he understood.

A pity he lied and said he had connected them up. As per usual with most 2nd year about to start their 3rd year apprentices.

You leave the dust covers on:-).

What's the timescale? A couple of months should not be a problem.

When the apprentice in the passenger seat smacked an undertaking cyclist in the gob I was full of praise for him.

10/10 to the apprentice. >
