Basic installation example 4  

Using the alarm pins to monitor door contacts  

To give your equipment room some security you can use widely available common door 
contacts. These contacts allow current to flow through them when they are in close 
proximity with each other. 

RMS-200

 can sense when the contacts are together or apart. 

Program the alarm pins to send an email, run a custom file, and/or toggle a relay when 
the door gets opened. The diagram below (figure 5) shows how to use Alarm pin 5 to 
monitor door contacts. 

Note1

: the LED5 light is on when the contacts are together. This is the armed position.

Note2

: each Alarm pin has a corresponding LED.
