Use this relay card on Stratos-HSSD 2 or Stratos-Micra detectors. On the Stratos-Micra it gives extra outputs so that relays are available for all four alarm levels and fault. On a Stratos-HSSD 2 it gives a second set of relays that duplicates the standard relays. The fault relay contact is normally closed and the alarm relays are normally open.
