PRODUCT DESCRIPTION
The DXS-80 is a carbon monoxide (CO) alarm with a built-in transmitter 
designed  for  use  with  Linear’s  DXS  and  DX  Format  receivers. The 
detector  gives  warning to  alert  against  both  the  acute  and chronic 
effects of CO poisoning. When carbon monoxide is detected, the alarm 
sounds a loud local alarm. When the  local  alarm  sounds, the  built-in 
transmitter  sends  a  digitally  coded  wireless  signal  to  its  companion 
receiver every  20 seconds  until  the  air  has  cleared  and  the  detector 
is restored.
The local  alarm can be  silenced  once by  pressing the TEST/RESET 
button. The transmitter will continue to send an alarm signal every 20 
seconds. After 7 minutes, the alarm will sound again if there is still an 
unsafe CO  concentration  level. The  reset  function  can  be  used only 
once for each alarm occurrence.
The  DXS  transmitters  are  precoded  at  the  factory  to  one  of  over  a 
million possible  unique  system codes,  so  no field  coding  is  required. 
Receivers  must  be  programmed  to  the  transmitter’s  code  before 
system  testing  and  operation.  Refer  to  the  receiver’s  instructions  for 
details on programming.
The unit is powered by one 3-volt lithium battery. The battery is supplied 
with the transmitter and can power the unit for more than one year. If the 
battery voltage drops below a preset level the alarm will sound a low 
battery chirp every 45 seconds and a low battery signal will be sent to 
the receiver (some receivers can report low battery, others cannot).
When the detector reaches the end of its serviceable life (after about 6 
years) a permanent trouble condition will occur and cannot be reset.
Maintenance: Occasionally clean the outside casing with a cloth. 
Ensure that the holes on the front of the alarm are not blocked with dirt 
and dust. Do not paint, and do not use cleaning agents, bleach, or 
polish on the detector.
