I'm busy faffing about with an Elkay, PIR replacement for a wall switch. Which I used to have, in the utility room, to switch the light on, when you walked in there, with your hands full. It worked fine, until the wall switch position, became hidden behind a new freezer, so I replaced it with another, fitted to the light itself - and again working fine, leaving the Elkay surplus.
I thought to now fit the Elkay, to the downstairs toilet, but cannot get it to switch off. It uses just L and LS, charging a small 3.6v NiCad. The NiCad shows 0.6v. Between L and LS shows a constant zero Ohms.
Would my guess be correct, that the L and LS, are connected across the NC contacts of the relay, and that the relay is powered open, when the PIR does not detect a presence? In other words, it would require the battery to have some charge in it, at installation time, or it would never open, to be able to charge the battery.
