Layouts change as these are fire detection systems installed in buildings (flats and houses) under construction. The properties have devices installed in them after roof is put on and remain protected until the plasterboard and Ames Taping is done at which point the devices are relocated to next...

I will speak to them again. However, if my memory serves me correctly I think there were a couple of issues with the wireless option. The first was power consumption as the wireless had to constantly poll the main panel and the sensors resulting in battery needing replaced more often (we could...

I can't remember why but using repeater in wireless rather than wired mode was not suitable for some reason and the manufacturer recommended we use the wired repeaters. They do have two short thin straight antennas built in to the circuit board arranged vertically and horizontally. Saquib.

Higgler, Just to be clear, we have the main panel which has the built in antenna then we have multiple battery operated smoke detectors with I'm assuming their own receivers. There is a wired "repeater" which connects to the main panel as well which can be used to extend the range of the main...

It seems so. They have also come back and said that they cannot retro-fit another antenna interface to device as it would require a complete re-design of the PCB. That's life. Thanks for your assistance in this matter. Saquib.

Thanks for the feedback, it has been invaluable. I think we will stick to installing multiple units to compensate for low range. Regards, Saquib.

The product we have adapted for use in this environment is made by HKC (www.hkc.ie) The product code is SW-1070. What I am keen to learn is if the manufacturer is not prepared to provide an interface for connecting bigger antennas then could we have this work carried out ourselves by...

Yes these are normal domestic intruder and fire detection devices. We have adapted these for use in the construction environment and they will be relocated once the fire risk has reduced (plasterboard and Ames Taping completed). The problem we currently face is that although the trials were...

We need to increase the range of 868Mhz intruder/fire systems to allow us to cover multiple buildings or floors within construction sites using a single control panel with paired wireless smoke/intruder detectors. Would I be correct in thinking that increasing the size of the antenna at the...
