toenee Posted June 28, 2006 Share Posted June 28, 2006 Have just been given some grade 3 flush contacts to fit they have eol resistors fitted and resistor across the contact but what a pain to fit, is this normal? Working of the manufacturer's spec I should have had 10mm clearance but this was very hitty missy! I eventually fitted one at a diagonal angle and the other one 5mm above the center line of the switch to make them work, Am I missing the principle of these double reed switches Link to comment Share on other sites More sharing options...
spider Posted August 31, 2006 Share Posted August 31, 2006 As this contact is magnetically biased, the magnet must be correctly aligned in relation to the contact, biased contact gaps are critical and vary with manufacturer and door construction Link to comment Share on other sites More sharing options...

Its about time that the security industry started fitting door switches that detect an extraneous magnetic field in close proximity. Link to comment Share on other sites More sharing options...
Guest Posted September 17, 2006 Share Posted September 17, 2006 Why not use a diff technology. Not hard to work out something other than a magnet is it! Link to comment Share on other sites More sharing options...
magpye Posted September 17, 2006 Share Posted September 17, 2006 "Its about time that the security industry started fitting door switches that detect an extraneous magnetic field in close proximity" You mean like we used to? Someone told me I was ignorant and apathetic, I don't know what that means, nor do I care. Link to comment Share on other sites More sharing options...

The manufacture did have a slip of paper in with them it said "align green band to green band" that did not work mind you it also said use a combination of cable colours to get the gardiner tech resistor combinations this was wrong and the correct ones given after a telephone call no advice given about the alignment though We are a small company and get well p****d with faulty gear or instructions we waste a lot of time on fault finding on new gear and don't see why we should be a proving ground Link to comment Share on other sites More sharing options...
