Product overview
  The 4 wire smoke detector 48vdc with relay that initiated the alarm condition will have its red LED and relays latched until reset by panel. Two LEDs on each detector provide local 360° visible alarm indication. They flash every six seconds indicating that power is applied and the detector is working properly. The LEDs latch on in alarm. LEDs will be off when a trouble condition exists indicating that the detector sensitivity is outside the listed limit. The detector has an automatic reset function.
