    >PIRs on the side, rather than on the top ...

    on second-thoughts, daft idea when there's a door !


    >IR break-beam sensor ...

    wonder if they wopuld have to be pulsed, for economy - ie: no idea about their power consumption ... ?

      Reed switches .... where else might they be useful, besides doors between rooms & doors to the outside ? Cupboards & draws, in kitchen, bathroom, wherever (but why) ?? Fridge, freezer, maybe (but how) ?? Anything else - like, maybe, for registering when things are in their place - tools, say, or ... what) ??

      Any ideas ? So we can wire accordingly, before we plaster !

        IR beam break sensors tend not to consume too much power The ones we install consume about 40 to 50mA. So not that much really.

          >IR beam-breaker ...

          which ones do you use ... are some better than others ??

          ----

          >50mA ...

          ie: 50/100 x say 10V x 24 x 365 / 1000 kWhr per annum @ say 7p each = about 30p per year ...

          real cost maybe half that, because helps heat the house !

          sorry, had to do the sum !

            I think they are Optex, as they tend to arrive unbranded. They are similar to these http://www.optexeurope.com/Site/temP...100&intLevel=6
            There are many types.
            Some have the emitter and receiver in one unit and then require a reflector.
            Others have an emitter in one unit and a receiver in the other. And some use dual or quad beam systems where you have more than one beam. And the beams may be on different frequencies of the infra red spectrum.
            The ones we use are of the dual beam variety, and are quite reasonable in price about 110 euros.
            You may want to have a look at these sensors http://www.optexeurope.com/Site/temP...g=2&intLevel=5
            Never used them so don't know how well they work.

            You could make your own optical beam if you are handy with a soldering iron http://www.electronic-circuits-diagr...rmsckt19.shtml

              thanks, interesting ... 'wonder if the Sequads would work well with Idratek ? ie: if the two signals would be picked-up OK ... presumably they both appear on the same wire within the cable & so would have to go to the same digital contact on an Idratek module ?

                The sequad unit basically outputs 2 signals one for the outside curtain zone and one for the center zone. These contacts are normally closed.
                I can send you the install manual if you like.

                  thanks ... sounds like each signal is on a separate wire withing the one cable, and the tamper-switch is on another, too ... if you have the manual electronically, then yes, please !

                    If anyone does find any tiny barrel type IR beams and receivers - the sort of size of the laser key chain pointers - that could be rebated into a doorway frame - do let me know - I'm sure someone must make them with a nice mounting flange arrangement.

                      I wonder if the Sequads would satisfy the dual confirmation requirements for alarm system nowadays ? I suspect maybe not as the two sensors are similar technology.

                        Yes they satisfy the UK ACPO (Association of Chief Police Officers) policy on Sequential Confirmation.
                        They are also DD243:2004 Compliant donīt know if this is the same thing.

                          Dragging up an old thread but had a search and can't find anything.

                          Has anyone got any suggestions for inconspicuous reed door switches?
                          I am looking at these at the minute but they may stand out in our wooden (i.e. not white) door frames.

                          Huge range of Fire Alarm Systems, Fire Alarm Panels, Domestic Smoke Alarms, Fire Extinguishers, Intruder Alarms, Carbon Monoxide Detectors, Batteries, Test Keys, First Aid Supplies, locks, locking products, architectural hardware - Next Day Delivery - Great Service


                          As per Karams suggestion I will be placing them at the top of the frame as we are not a family of doors fully closed but they tend to have a shove

                          Thanks
                          Allan

                            This is the standard one we use for Idratek installs,
                            For dark wood frames you can paint with the two part would grain effect paints and they blend in OK.

                              Thanks Viv... if they are good enough for the professional install then they are good enough for me!

                              Good idea about the camouflage as well..

                                Forgot to post some more info on the Optex Sequads.
                                So better late than never.
