TESTING
Applying a magnet to the side of the EVD-M controller, (see Figure 1), actuates a
magnetic switch and generates a test signal. Similarly, applying a magnet to the side of
an EVD-R remote pickup , (see Figure 3), actuates a magnetic switch and causes the
EVD-R to transmit a test signal to the EVD-M controller. In both cases, the EVD-M:
detects these alarm conditions, activates the alarm contacts, activates the alarm remote
annunciator, and illuminates the status LED in RED.
NOTE: Most ordinary door contact magnets will activate the test feature on the
EVD-M and the EVD-R.
System operation can also be verified from a remote location by use of an optional RTA
and/or a UL listed central station test unit. Operating a normally open test switch
generates a test signal which causes the EVD-M to signal an alarm condition.
NOTE: Always test unit prior to placing unit into service. Unit must be tested
at least once a year.
