OPERATION AND USE OF THE SEMS II DISTRESS ALARM
(PASS)
ACTIVATION
Prepare the respirator for use according to the user instructions provided with the
respirator. Install the batteries in the SEMS II Sensor Module according to the BAT-
TERY INSTALLATION section of this instruction.
The SEMS II distress alarm device is automatically activated when the respirator is
pressurized by opening the cylinder valve of the respirator. To indicate activation, the
sensor module will sound 3 quick audible chirps and the green light located on the
control console will flash approximately once every three (3) seconds. The SEMS II
distress alarm is now in sensing mode.
Once activated, the SCOTT SEMS II distress alarm constantly monitors motion of
the respirator backframe. The sensor module is located on the respirator backframe
beneath the air cylinder and contains the motion sensor and the audible alarm. If the
sensor module does not sense motion of the respirator for twenty (20) seconds, the
SEMS II distress alarm will signal a pre-alarm condition. If there is still no motion of
the respirator for the next twelve (12) seconds the full alarm will sound.
The SCOTT SEMS II distress alarm will remain activated until turned OFF according
to these instructions.
