JasonOfOz Posted September 5, 2014 Share Posted September 5, 2014 Hi Everyone, We have a clent's offices where the lifts open directly onto the office floor. I have put a dual tech detector across the front of the lift doors but need something else to give me a confirmed alarm. Has anyone got any thoughts/recommendations as to what to install onto lift doors? (Is there a contact that can be installed onto them?) Alternatively, could we just position a quad detector infront of the lift area (so that it doesn't overlap with the dual tech) to give us the confirmed if anyone steps beyond the area where the keypad will be located? Thanks Link to comment https://www.thesecurityinstaller.co.uk/community/topic/37335-door-contacts-for-lifts-what-would-you-suggest/ Share on other sites More sharing options...
norman Posted September 5, 2014 Share Posted September 5, 2014 Can the lift Co give you an output? Save faffing. Nothing is foolproof to a sufficiently talented fool.

JasonOfOz Posted September 5, 2014 Author Share Posted September 5, 2014 That's a good idea. Mind you I tend to give lift companies a wide berth because they seem to have a license to print money when you ask for the simplest of things. Plus generally any wiring needs to be run from the lift motor room which is sometimes quite labour intensive. Hopefully I will be pleasantly surprised, so will ask the question. Thanks!

antinode Posted September 5, 2014 Share Posted September 5, 2014 As breff. Optex make some flush units that are much less obtrusive than the regular type (AX-100sr) Also, not a problem over-lapping a quad and a dual tech or two dual techs, it's two PIRs you can't over-lap.

jiml Posted September 5, 2014 Share Posted September 5, 2014 TMD is a good solution but if the detector is the FE then it will never cause a confirmed alarm. Could you aim your DT at the lift door and the TMD away from the door. As in after the keypad. Not ideal but may work.

TMD is a good solution but if the detector is the FE then it will never cause a confirmed alarm. Could you aim your DT at the lift door and the TMD away from the door. As in after the keypad. Not ideal but may work. Yes well as it's near the lifts, one of them will be the final exit one. So can someone explain what the rule is on overlapping areas? Previously I thought by using a TMD would mean I would only need a single detector - now i understand that's not the case, so what is the point of a TMD?
