[QUOTE="SPECIAL LOCATION, post: 443837, member: 250"] Just thinking this through.... 1/ A lot of bog-standard PIR switches have a relay contact as the output to switch 230v to a load..... So if this relay contact is wired in series or parallel with other switching devices its unlikely to have any effect on the PIR sensor detection circuit that triggers the relay. 2/ A lot of bog-standard dimmer switches can be used as a two-way switch... where the dimmer could be put at either end of the two-way circuit.. and the common can be connected to either supply OR load without any detrimental effects.... 3/ So.. If you wired such a dimmer in parallel with a standard switch OR a PIR relay contact switch all you will do is put a 230v potential at both side of the dimmer.. so the potential difference across the dimmer circuit will be 230v-230v =0v Cant see how this would damage the dimmer circuit... :C [/QUOTE]
