Note:
1) Only displayed if channel 3 is used on a device.
2) These are the values that the device would
transmit to the control panel. The values do NOT
include any calibration or correction factors.
MEASURE TEMP
This feature measures temperature in degrees Celsius and
degrees Fahrenheit, but is only available on detectors which
have a temperature sensing element, ie, Heat only, Optical
&
Heat and CO & Heat detectors. A typical display is shown
in b):
MEASURE CO LEVEL
For CO detectors only. Gives values for CO levels in the
measuring environment. Normal value is zero PPM (parts-
per-million).
SELF TEST
This menu option performs a self test for detectors which
have this facility.
• Select SELF TEST to display the sensor
analogue values (a)
• Select ON to perform the self test; wait
10seconds to see if PASS is displayed (b)
• If FAIL is displayed, then the detector is
faulty and must be replaced
b)
Self Test is available on the following types of detectors:
• MX Ionisation
• MX Optical + Heat
(Optical sensing element only)
• MX CO + Heat
(CO sensing element only)
Note: Self test is NOT available for the heat sensing
channels of these detectors.
DIRTINESS
Available for Optical detectors only. 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 maximum 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.
Note: Dirtiness can be displayed as a negative
number if the analogue value has fallen since
manufacture.
SERIAL NUMBER
Select SERIAL NUMBER from the main menu and the
unique preset factory number of the device in hexadecimal
will be displayed.
Note: This number cannot be changed by the user.
MANUFACTURE DATE
Selecting MANUFACTURE DATE shows the date of
manufacture of the device. Press ‘Menu’ to return to the
main menu.
