2 contacts confimed right away, or intruder if lifted from one side..

Beam Pair if on seperate zones or series


One action shouldn't send a confirmed.
Like fitting Shocks or BGU's too close together, for example.

[jameswilson]

agreed you cant confirm like that

[9651]

Same tech also

We tend to fit one, never been pulled up about it, then either DT, or AX across the door

still no confirmed if they check which end is contacted and pop the other.
We have had to fit beams on a few sites due to being rammed with fork lift and not activating the contacts.

[9651]

Aye, most doors we see are either fastened down from the inside, or locked halfway up, so popping them out would be hard going?


Still, one site we had a hole cut IN the door. Big cat flap type job, wish I got a pic!

Unlucky for them there was AX across the door and D/T in loading bay

[jameswilson]

if the shutter is that big then yes 2 contacts either in the same confirm group or in series is a good idea but not a requirement. Also if the door is dodge id also spec an active beam. agree with the trap protection of an overlooking dt

[antinode]

Is there anything that says shutters have to be contacted? IE would two dual techs covering the area inside the shutter not be a better, easier, less faffing around solution?

lol thats what Astra alarms do, bit rough on G2 with no mask IMO.

[jameswilson]

anti
Nowt no
anti mask is about risk on the site. Most people do G2 afaik so to generalise that its weak imo goes against most opinion. I personally would go for contact and trap protection on the view. There is an en guideline that dictates this but its optional so far

I hate RSD contacts they fail far to often for my liking.

We have started fitting 2 x Guardall DT 15+ at each side of the shutter (with the mask connected as we only fit G3 Galaxy on monitored jobs)
Our Fa rate is very low and we dont get stupid callouts to rotten RSD contacts.

Even if the job is G2 we connect the mask on 99.9% of the detectors.

I thought the point of using door contacts is to ensure the site is secured before the sub leaves ?

eg-- leave stock in the door way & return to nab once everyones gone home ?

As did I? Think most insurers think the same.

[norman]

ditto, to stop the setting procedure, also trap protection only leaves a higher probability of fa's

KP do plaggy spacers to lift G3's of metal surfaces, I wonder in 5mm of plaggy would help prolong the life of RSC which oftend sit in the wet ?

We use them on most RSC's now, seem to have much less trouble.

Many, many years ago I had a friend who worked for a company called Magnetic Shields.

He used to give me 'off cuts' of one of their magnetic shields, they were like pieces of soft black cardboard about 4 or 5mm thick.

I used to cut it to fit the size/shape of the magnet to be fitted and used that as the spacer, absolutely no problems, even the heaviest magnet would not 'stick' to the most solid metal door.

Wish I still had access to this.

I don't quite follow you?

I'm saying one of these bunged under the contact
