Operation
7.1
Normal operation
When the Analox CO
Clear
is turned on it will take approximately 40 seconds to warm up
and stabilise. During this period, the 'Good/OK' and 'Fault' status indicators will be turned
on. After the initial stabilising period has expired, the 'Fault' status indicator will turn off.
The 'Good/OK' status indicator will be illuminated and flash off briefly every few seconds,
indicating normal operation. The status indicators on any Alarm Repeaters will mimic this
operation. On display models the display will briefly read ‘.8.8.8.8’ on power up before
reverting to the CO reading.
7.2
Alarm indications
If the Analox CO
Clear
detects a CO concentration which is greater than the first alarm
level, then the 'Alarm 1' indicator will begin to flash and the buzzer will sound at its slow
speed.
If the measured concentration of CO continues to rise above the second alarm level, then
the ‘Alarm 2' indicator will begin to
flash, and the buzzer will sound at its medium speed.
The 'Alarm 1' indicator will continue to flash.
On standard units the alarms are self-cancelling when the CO level drops below the alarm
limits.
Momentarily pressing the 'Mode' button on either the Analox CO
Clear
or any Alarm
Repeaters, in the absence of any alarm conditions, causes an alarm test to be performed.
The indicator lamps will flash 4 times and the buzzer will sound.
In all circumstances the Alarm repeater will mimic the status indications and buzzer of the
main unit.
Units fitted with relays are configured such that relays may operate in conjunction with
Alarm1 or Alarm2. They are factory set to be energised in the absence of alarms, and de-
energised in the presence of alarms. They may be factory configured in the opposite sense
if required.
