Can You Identify This Limpet

[dwdave 0]

 

Contacts left to right CCT+ / CCT-   BATT+/ BATT -   A/T

 

CCT opens and closes with the reed switch

A/T opens and closes with the tamper switch

BATT - I have no idea why it would have battery

 

Im guessing the vibro wires in from its own contacts

 

I have no instructions, or makers details but would like to find out how to rig it up.

 

There is also a junction box in the keep.

 

Im guessing a flexi / armoured loop from the keep to the limpet is what it needs?

 

in advance!

It's a Safe Limpet with a rather old fashioned mechanical shock sensor. The sensitivity of the pendulum is adjusted by means of a screw. Shock sensors of this nature required NC connection. Never come across a Keep and limpet, always thought that a safe limpet was a single unit.

Thank you -  ive only ever used one before in an old job and that had a keep. 

The backplate seems to have the same pattern as the newer elmedene ones. Perhaps its an old Elmedene unit?

Would need to dig through my old specs (two suitcases full) to be sure of that one's identity.

Case and layout deffo looks elmdene but even the old BNIB ones I've got from early nineties aren't quite the same.

 

Footprint seems identical though. 

[dwdave 0]

It is a BNIB - dated '88.

[datadiffusion 489]

Ah slightly earlier than mine. I bought a 'lifetimes' supply on clearance, of varying dates and models but all Elmdene, although of course since

then we have PD2010 (not that I'm approved) and most panels no longer offer on board analysers, of which 50% of my 'collection' require!

So my panel (Galaxy Classic) wont analyse the vibro is that correct?

 

If its that old, im tempted to fit a new vibro into the limpet anyway.

[datadiffusion 489]

Oh it might do - lots of others are more expert on that panel than me.

 

I know that Scanny have dropped it, SPC might still have it, Texecom maybe, Risco never?

[dwdave 0]

I'll await an expert - but Zone Descriptor 47 - Vibration - leaves me feeling a bit more positive.

any galaxy panel wont do inertia monitoring you need a separate analyzer 

only panels that have this builtin are Aritech, HKC

ok, but it will take a more modern shock sensor - they have the analyser built in dont they ?

Pre-ion, non EN common platform Scanny and current SPC do too though, AFAIK.

 

But there are very odd issues with Scanny on later panels where its offered on all zones but will fail on anything but 1-4, there

was a tech bulletin but deleted recently by Eaton in the name of progress. Agreed its pretty old info.

Yeah the Siemens spc has analysed circuits. As nova the galaxy does not

looks like i might get the soldering iron out then and strip of that old shocker and fit a new one then!

 

I cant grumble - got a limpet delivered for £8

[norman 823]

Looks like when it was advertised on fleabay they only showed the reverse side... I wonder why...

[Nova-Security 91]

Honeywell sc100 is the proper way

[9651 12]

Buy an analyser if you must?

[dwdave 0]

Buy an analyser if you must?

 

Is it that simple?

 

Should I not just add in a "proper" shock sensor?

[datadiffusion 489]

How about a proper self analysing limpet if you really need one?

[Simlec 24]

I should hope your system has sent you conformation that there are intruders before you need a safe limpet?

You would be better putting a PA next to safe in case you are ever frog marched to it.

[dwdave 0]

The limpet really is just to chime out in case the safe is opened whilst the alarm is unset. I dont want the children playing with the safe.

 

It sits in view of a PIR when the system is set.

 

I dont really require a limpet worth mega bucks. No laws or insurance policies require me to have an alarm let alone a limpet but to coin a phrase - every little helps.

 

So if adding a self analysing vibro inside the limpet would work then I am happy to do that.

 

I am also currently building a communicator to call me and email me ( and a list of keyholders)  if an alarm is triggered - so its a loosely monitored alarm I guess.

Bit of a moot point with his phone ringing in his pocket telling him his alarms gone off...

"....... hang on a second ........ let me get that ....."

 

<<its the wife>>

 

"She says shes cleared out the safe and left me!"

You couldnt hear the phone ringing for the sounders !

be better if you said what your trying to achieve there may be better ways. But 8 quid to protect your safe you may as well save the 8 quid and bury it in the garden under a 12 quid bird bath
