244.x.3
Common Defect
This point is in fault if there is a fault at the RZDU. It will be
necessary to review the fault at the RZDU itself.
244.x.4
Batt Fail
This point is in fault if the battery has failed at the RZDU.
244.x.5
Charger
This point is in fault if the charger is out of specification at the
RZDU.
244.x.6
Mains
This point is in fault if the RZDU has no mains supply.
244.x.7
Silence Alarms
Not used in Australia.
244.x.8
Trial Evac
Not used in Australia.
244.x.9
Serv Restore
Not used in Australia.
244.x.10 Self Test
This point is in fault if the RZDU has failed its self-test.
Value x is the RZDU number.

Description
245.x.0
Loop x Left S/C
Indicates a short circuit on the left hand side of the
MX
Detector
Loop. The point state is Fault if a short circuit is detected
between the AL+ (J1-1) and AL- (J1-2) terminals, otherwise the
point is Normal.
245.x.1
Loop x Right S/C
Indicates a short circuit on the right hand side of the
MX
Detector
Loop. The point state is Fault if a short circuit is detected
between the AR+ (J1-3) and AR- (J1-4) terminals, otherwise the
point is Normal.
245.x.2
Loop x Open Circuit Indicates that an open circuit fault has been detected on the
MX
Detector Loop. The point state is Fault if an open circuit is
detected on either the +ve wire or the -ve wire, otherwise the
point is Normal.
245.x.3
Loop x Overload
This point indicates an over-current fault on the
MX
Detector
Loop. The point state goes to Fault while an
MX
Loop overload
induced reset takes place and also if there have been 5 of these
resets within the preceding 5 minutes, otherwise the point is
Normal.
245.x.4
Loop x Polling Rate Indicates an
MX
Polling loop rate fault condition. A fault state on
this point occurs when the
MX1
is unable to communicate with
the MX loop devices quickly enough, which may affect correct
operation of detectors and modules. The fault condition will
remain for 30 minutes from when the
MX1
becomes able to
communicate quickly enough. The fault condition can also be
cleared by resetting this point
– if the fault condition remains the
point will re-enter the fault condition within a short period of time.
245.x.5
Loop x Left Relay
Status
Display AL Relay status (open/close).
245.x.6
Loop x Right Relay
Status
Display AR Relay status (open/close).
245.x.7
Loop x
Communication
Status
Indicates whether the loop card is operating or not.
“Normal” = operating
“Fault” = not operating, or disconnected, or plugged into the
wrong port.
245.x.8
Loop x Flash CRC
Status
The result of comparing the Expected and Actual CRC of the
Loop Card Flash Memory -
“Normal” or “Fault”
245.x.9
Loop x RAM Test
Status
The result of the most recent RAM test on the Loop Card -
“Normal” = passed
“Fault” = failed
245.x.10 IR Mode On
Active when infrared mode is enabled for
MX
loop x. Places the
MX1
into the off-normal state.
The above points are repeated for each configured
MX
Loop Card.
