Can You Identify This Limpet

[dwdave]

 

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?

[charlie6]

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]

It is a BNIB - dated '88.

[datadiffusion]

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]

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]

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