Press
to change
The list "wraps around", so that pressing
when viewing Address 001 brings up detector number 127.
Pressing allows the user to remove a detector address from the loop (by changing
Y
to
N
), or to re-
instate a previously removed detector (by changing
N
to
Y
). This is different from the Isolate function in
that a fault is still generated on the Command Module. However, this may need to be done if replacing a
detector on the loop so that the detector’s address becomes available to the replacement. After replacing
the detector, the address may be re-enabled.
1.1.1 Looped Bus (Yes/No - CM only)
Setup Menu > Bus Setup
This function is set to
Yes
to signify that the detectors are connected to the Command Module in a fault
tolerant loop configuration (see section 185619544.01.1.1 “Fault Tolerant Detector Loop Configuration”
on page 46 for details). Failing to set this value to
Yes
for a loop configuration will mean that the fault
monitoring advantages of the detector loop are lost. Setting the value to
Yes
for a non-fault tolerant
configuration will generate detector loop errors, so it is important that the appropriate configuration is
identified.
1.1.1 Poll Timeout (Numeric - CM only)
Setup Menu > Bus Setup
This is the time, specified in milliseconds, which a device has to respond to a poll from the command
module. If no response is received for this time then a
Comms fault
message is shown for this device
on the Command Module display. This may be caused by communications delays, for example, when
units are communicating across a Wide Area Network. This function may then be set to a more suitable
value.
NOTE: If in doubt about the setting of this function, please contact the Hochiki Europe Product Support
Department (see page 2).
1.1.1 Call Centre (Numeric - CM only)
Setup Menu > Pager
This is the phone number the modem dials up to send a message. For further details on this and the
other functions in the "Pager" submenu, see section 231156696.01.1.1 “Paging from the Command
Module” on page 42.
1.1.1 Password (Alpha - CM only)
Setup Menu > Pager
This is an optional password used to access the system.
