Many thanks for the replies, by the way. I can't use the HKC (or any other control panel system) as both family members are elderly, and can't cope with a control panel. They just want an alert, like mine, that tells them someone is walking down their driveway. Even a Ring is pointless as the notification to the user is far too delayed in time (and sometimes non-existant!).

Al-yeti, yes that's exactly what I did 15 years ago! I simply put a washer inside the bell push that makes permanent contact, so as soon as the Takex sends an alarm output, power (12v using a transfomer, and ditching the internal battery) is sent through the bell push button and alerts the indoor chime. It has worked an absolute treat. We NEVER get a false alarm, either! However, this time I need to use the Optex, and unfortunately that has 3.6v rather than volt-free connections. Optex have told me to use a 'PCU-5'. I don't know what that is, but I assume it drops the voltage to 3.6v. That's no good as 3.6v won't operate a wireless door chime button. I will Google 'HKC alarm'.

Well I just wondered if the market had provided something new. I fitted a Takex system 15 years ago. It spans a 12 metre gap and is wired to a wireless doorbell chimer. It has worked flawlessly, and I really can't fault it. The only reason I'm not going down the Takex route this time (for two family members who want the same system) is because of the cost of Takex, now. I can rig these two systems up to a doorbell chimer, no problem, but I was just hoping that some manufacturer somewhere would be providing the same idea (at 3.6v) without me having to re-work a doorbell button. IF I remember correctly, my 15 year-old Takex has two volt-free terminals for the alarm output (presumably activated by a relay?), whereas the Optex system I link to above apparently has 3.6v terminals...if I've grasped this correctly. So that is my 'problem' - that doorbell chimers are 12v not 3.6v.

Yes, I need the alarm output to send a wireless signal to a chimer inside. Is there something off the shelf? I did contact the manufacturer, but (although very helpful) wanted me to spend hundreds on a control panelled receiver and signal emitter. Given that wireless doorbell chimers do this for just £12, I wondered if any company had produced something similar to simply wire into the alarm output terminals.

I'm open to suggestions of a different product. I want to protect a driveway with a perimeter beam, but there's no way of running power out. So it has to be a perimeter beam that is battery operated. And obviously I need that to trigger an indoor chimer/sounder wirelessly. Any suggestions very gratefully received. Thanks.

Yes, this is to be used to protect a driveway - it DOESN'T have wired connections, it is a stand-alone battery unit. So any alarm output has to be wireless. On the spec, it says the alarm output is 3.6v http://www.securitywarehouse.co.uk/brochure/AX-100_200TFR.pdf So I assumed I can't simply use a 12v wireless doorbell chimer. Am I wrong? Thanks.

Can someone kindly advise me? I am going to install a photo electric perimeter beam (Optex AX-100TFR) which has an alarm output of only 3.6 volts DC. All the wireless doorbells chimers I'm coming across use 12 volts. Is there a 3.6v wireless chimer available anywhere? Thanks very much for any replies.
