Obsolete Timeguard PIR

[ImpededLoop]

A potential customer has an external light control system originally manufactured by Timeguard. There's a controller in the loft space which has a 2 core cable to each PIR which seems to be a bus wire. The PIR's are now failing, part number: SL099. I've found them on Google but they are discontinued and nobody seems to have any available.

Does anyone know anywhere that may stock them? I know it's more likely that the system will have to be replaced. Is there a similar system that uses a two core cable to link the PIR's to a central controller?

There was a similar post on here in 2015 which got not replies, but I thought that it was worth a try

there are similar systems with PIRs on 12V. Voltek and GED.

Cheers Tel. Voltek looks good, thanks. I couldn't find GED online though.

EDIT: Just noticed the Voltek needs three wires. Unfortunately the existing installation only has two.

This is only thinking outloud, but would PIRs intended for alarm/security systems be compatible?

The existing PIR cables are only two core, so probably not unfortunately.

It's probably the same system as timeguard took over smiths years ago.

Do you mean GJD? If so they'd be no good as they need more than two wires.

if you google smiths 12 volt security system it bring this site up, in 2015 the famous tazz replied with full instructions that a gjd opal will fit it, the piccy is same as our system

Many thanks for looking it up. Unfortunately the system that I was asked to repair is a two wire system.

Many thanks. I think this will be the only way to do it without rewiring the PIR's
