Hi All - I am changing a burglar alarm pir to a magnetic contact switch. The contact switch has 3 silver screw terminals called 'Contact Circuit' and 2 brass screw terminals called 'EOL or Tamper'. What wire do I connect to what terminal, I have black and red (power), white and yellow (relay) and blue and green (tamper). I have tried numerous combinations without success. Thanks in anticipation of your assistance. [/b]
