6-3-5 Check for Devices Needing Service
When activated this function reads the drift compensation value of every Discovery™ device connected to
the system.
Any devices that are close to their drift compensation limit (and therefore will shortly be in need of
servicing) are reported via the normal fault reporting mechanism. These ‘FAULTS’ will have the message
‘DEVICE NEEDS SERVICE’. They can be reviewed once programming mode has been exited. Because
they are reported as ‘FAULTS’ they are recorded in the event log and can therefore be reviewed and printed
out using programming functions 1-1 and 1-2.
'Check for Devices Needing Service' reports ‘DEVICE NEEDS SERVICE’ when the device drift
compensation is less than 6 or greater than 28. (The device itself will set it’s drift flag at compensation
values of 3 and 31 which will result in the system reporting a ‘DRIFT WARNING’ fault for the device.)
6-3-6 Read Data Stored in Device
Allows any of the data bytes stored in any Discovery™ device connected to the system to be read.
The byte read is displayed in decimal.
Reads will only be attempted on sub-panels that are set for Discovery™ detectors.
If the chosen device is not a Discovery™ device an error will be reported (this error is not logged).
6-3-7 Write Data Stored in Device
Allows a decimal value to be written to any of the four 8-bit user data locations in any Discovery™ device
connected to the system starting at address 11. The values that can be inserted must lie within the range
0-255, otherwise it will cause an overflow of the byte value.
Writes will only be attempted on sub-panels that are set for Discovery™ detectors.
If the chosen device is not a Discovery™ device an error will be reported (this error is not logged).
One sample application for this capability would be to record in each Discovery™ compatible device the
installation date (month/year). Using one byte for the month and another for the year. Another one would
be to insert a code or reference for the installation.
NOTE:
When this function is activated it is necessary to read from every Discovery™ device
connected to the system. This can take 60 seconds. During this time do not select any
Discovery™ Specific programming functions (6-3-X).
