What confidence test functionality does the A50 offer? How do I use it? 


A confidence test is provided to prove the device sounder and all lamps work.

To conduct this test momentarily press the ‘Mode’ button on either the A50 or any Remote Alarm Repeaters, in the absence of any alarm conditions, this will cause a lamp and alarm test to be performed. The indicator lamps will flash 4 times, together with the alarm horn. Analox recommends that this confidence test is carried out each time an area is entered, however local risk assessments should be carried out to ascertain appropriate test frequency.

The A50 alarms can also be tested by passing the appropriate gas (ie 0.5% or 1.5% CO2) over the device sensor.
