   Facdir Inc. offers
 the SELF DIAGNOSTIC/SELF TEST(SDT)
 feature on many of its exit and emergency lighting
 fixtures.

  This feature is becoming increasingly more
 important in the world of exit and emergency lighting as architects and building owners become more aware of its tremendous value added functions and safety assuring technology.
 
  The heart of the SDT feature is the on-board IC chip that continuously monitors the
 entire fixture and reports any malfunctions via a user interface. The user interface
 identifies the exact nature of the problem allowing the occupant or service personnel to
 take the proper steps to correct it.

  The SELF TESTING feature included in the circuitry tests the fixture every 30 days for
 15 minutes and once every 12 months for a full 90 minute discharge test simulating a
 maximum use power failure. After each test it recharges the battery automatically and
 returns to normal operating mode. any problems found during or after the test are
 reported through the user interface.

  This SELF TESTING feature actually helps prolong the life of the batteries by keeping
 them exercised and fresh. Without the SDT feature, the battery can remain idle for
 long periods time, only being used in an actual failure and thereby depleting their ability
 to hold and maintain a proper charge.

  Self Diagnostics are available on various Facdir Lighting fixtures by specifying suffix
 "SDT".  Look for this symbol throughout the website or consult the factory.
