1.
detector diagnostics
Detector diagnostics cover all major circuits on the detector head and detector
controller boards. Each test is indicated as it is being carried out, followed by a pass/
fail.
2.
Detector continuous read
This menu item shows the detector output and air flow rate as continuously varying
percentages. Press any key to end the display.
3.
Controller diagnostics
The control board is the board on the front panel of the Stratos. All circuits tested are
followed by a pass/fail.
4.
Slave loop error rate
Interference on the slave loop can cause corruption of the data passed between a
master and it’s slaves. This is compensated for by the Stratos master but too much
interference could indicate an installation problem. The slave loop error rate is the ratio
of good to bad transmissions over the slave loop.
5.
Display dust separator condition
Selecting this menu item displays the current dust separator condition for all detectors.
The condition starts at 99% and when it drops to 80% a separator renew is displayed
on the front panel and the fault relay is activated.
6.
Relay test
Prompts for a detector number of the relays to test and then goes through the
following sequence of relay activation:
Aux
Pre Alarm + Fault
Fire + Fault
Fault
Pressing the 'RETURN' key goes to the next test.
