4.4.2.1.9 Sensor Check
INSTRUMENT
SENSOR CHECK
Performs a test of the system’s integrity including the sensor and checks for
proper operation. An optional gas-generator is required to perform this test and
must be attached to the end of the sensor housing. Available menu selections
are:
•
MANUAL
•
AUTO
Normal alarm operation is temporarily disabled during this test. Performing
the sensor check procedure is not intended to be a substitute for periodic
calibration.
MANUAL MODE:
Available selections in the manual mode:
•
CANCEL
•
TEST NOW
Selecting cancel will abort the sensor check procedure. Selecting test now
will begin the sensor check procedure and the display should revert to the run
mode display automatically. The sensor check procedure basically consists of
three phases:
1. Test-gas generation
2. Test-gas sensing
3. Display of results- pass/fail, bad sensor, bad generator.
Duration of the test is about 10 minutes.
AUTO MODE:
Available selections are:
•
ENABLE
•
START TIME
•
INTERVAL
AUTO
ENABLE
ENABLE configures the receiver to perform the sensor check procedure
automatically at the specified time and at the specified intervals.
The START TIME format is similar to the set time format and appears as follows:
ENTER TIME (HHMM)
HHMM
This menu requires numerical entry of the desired sensor check starting time in
24 hour clock mode. For example, 1 PM would be entered as
1300.
INTERVAL allows the automatic sensor check to be performed
periodically at pre-determined intervals by entering the time, in hours,
between periodic tests. The format is as follows:
ENTER INTERVAL (HRS)
HHH
where HHH represents the desired number of hours between sensor checks.
The unit will accept any value between 0 and 255. Selecting a value of 0 for this
parameter will disable the auto sensor check and has the same effect as selecting
disable in the auto mode, above.
