4.1.2 MEASURE TEMP
This feature measures temperature in degrees Celsius and
degrees Fahrenheit, but is only available on detectors
which have a temperature sensing element, for example,
Heat only, Optical & Heat and CO & Heat detectors. A typi-
cal display is shown in b):
4.1.3 MEASURE CO LEVEL
This option is only available for detectors with a CO sensing
element. It indicates values for CO levels in the measuring
environment. The normal value is zero PPM (parts-per-mil-
lion).
4.1.4 TEST ALL
This option combines a test on the detector R1 and L2 ter-
minals and tests the detector’s sensor circuitry for units
which have this facility.

The Test R1 terminal tests the remote indicator output.

The Test L2 terminal tests the functional base interface
output.

The Selftest tests the sensor input circuitry. Completion
of the Selftest may require a maximum of 30 seconds.
Following the completion of all three tests, a test report is
displayed on the LCD. Each test can result in a
PASS , FAIL
or NOT AVALABLE report message.
To start a new test, select the TEST ALL menu to begin.
WAIT is displayed until all tests are completed.
When the tests are complete, the test results are reported
on three alternating displays:
Self Test is available only on the following types of detector:

FC400PH O Heat (Optical sensing element
only).

FC460PH O Heat (Optical sensing element only)
4.1.5 DIRTINESS
This option is only available for detectors with an optical
sensing element. Indicates the contamination level of the
optical chamber. Compares the current optical analogue
value as a percentage where 0% would indicate that the
analogue value has not changed since manufacture, 100%
would indicate that the analogue value has risen to its max-
imum allowable value (the point at which it would generate
a fault). At 80% or above, the detector should be replaced
to avoid the possibility of a fault occurring in the near future.
4.1.6 DEVICE TYPE ID
Device Type ID displays the unique value associated with
each addressable device Model Number, for example, for
Model No. FC400PH - Type Value 10 is displayed.
a)
b)
Selftest
Self test is NOT available for the heat sensing
channels of these detectors.
Dirtiness
Dirtiness can be displayed as a negative number
if the analogue value has fallen since manufac-
ture.
