COMMAND MENU
The Command Menu allows the operator to initiate a manual oi test and also to perform various reset/
clear functions.
1) Start Passive
oi
A
passive
oi test command checks the cleanliness of the detector’s
optical surfaces. This confirms the ability of the detector to respond
correctly to an IR signal. Fire and fault relays as well as 0–20 mA
current loop output are unaffected by this test. A red LED signals a
successful test and a yellow LED signals a failed test. The event log will
indicate
either
“Man
oi Pass” or “Man oi Flt."
2) Start Active
oi
CAUTION
An active
oi
test generates an actual Fire Alarm Output. All fire
response equipment must be bypassed/disabled prior to testing to
prevent unwanted output actuation.
An
active
oi test performs an oi test with all detector outputs fully
operational. Fire and fault relays as well as the 0-20 mA loop are “live."
If the test is successful:
Fire relay = Alarm
Fault relay = no fault
Current output is 20 mA
LED turns red
General log indicates “Man oi Pass”
Alarm log indicates "Fire Alarm"
If the test is unsuccessful:
Fire relay = No Alarm
Fault relay = Fault
Current output is 2 mA
LED turns yellow
Fault log indicates “Man oi Flt”
3) Clear
oi
Fault
If the cause of the fault has not been corrected, subsequent
oi
faults will
occur.
4) Reset Latches
Latching relays are reset and LED turns green.
5) Master Reset
This function re-initializes the microprocessor, resets the operating
software, and initiates a hardware reset for both the sensor and the HART
interface. Latched relays are reset.
6) Clear Data Log
This function resets the HART data log history. To view the logs, go to
“Device Info Menu” and select “History Menu."
7) HART Cmd Menu
This menu performs various diagnostic and/or service functions.
