Pager
Numeric - CM only: Note: This is the number of the actual pager.
Page on fault
Yes/No - CM only: Where a pager has been allocated as above, this function
determines whether the pager holder is to be paged when a fault condition is
generated by the command module.
Page on alarm
Yes/No - CM only: Where a pager has been allocated as above, this function
determines whether the pager holder
is to be paged when a fire alarm condition is generated by the command module.
View event log
Display - Address 000-127: This function shows the start and stop time and
date of events such as FastLearn, alarm condition and error messages. (See
“Event log” on page 55 for more information on logging events.) The event log
can also be downloaded to a PC via the RS-232 serial port. (See “Connecting to
a PC” on page 35 for details on how to connect to a PC.)
Diagnostics
Test - Address 001-127: This function puts the detector into self-test mode. On
a command module, it tests all detectors on the loop.
Detector read
Display - Address 001-127: This function displays five values as shown:
010.5%
064 067 066 067
The top value is the detector’s current smoke level reading as a percentage of
the full-scale value, and the bottom four readings are the current flow rates on
each pipe. The flow rates are scaled based on the application. The absolute flow
reading is less important than a change in the reading.
Loop errors
Display: This displays the percentage of loop errors in messages addressed to
the detector or command module from the detector loop, along with a count of
the number of received messages since the last message was received on port 1
and port 2 of the RS-485 bus.
