7. Equations may be entered for relays 1-64 even through the appropriate 8 Relay
Modules are not fitted. The resulting states could be sent to an RDU or another
device on the RZDU bus.
8. When driving the fault relay with logic, the following should be noted.
The fault relay can be controlled with logic by the equation
FLT = ... - some logic
It is recommended that the SFT token is included in the equation for the fault relay.
e.g.
FLT = FLT + SFT + …
The FLT token is true when one or more MAF mapped non-isolated zones or
module/ancillary relays are in fault.
The SFT token is true for system faults - these are listed in detail in section 6.6 of
the F3200 Operator's Manual LT0119.
With no logic equation driving the brigade fault relay, the relay will energise for the
following things.
1. non isolated maf zone/relay faults
2. all battery/ mains/ charger faults
3. RZDU system faults
4. circuit failed system auto test
5. network associated faults (discards, scan fails, zone or system faults received
from other panels)
6. NZ mode defects (NDU only)
If you drive the fault relay with logic
FLT = FLT + SFT
then the fault relay will energise for some additional conditions which don't cause the
fault relay to operate when there is no equation FLT = …
These include the conditions which normally cause the Standby relay to de-energise
rather than energising the fault relay e.g. EEPROM database checksum error or
LED display board fault.
For network systems, FLT = FLT + SFT does not include zone or system faults
received from other panels.
9. For network systems, when driving the isolate relay from logic, the equation
ISO = ISO
does not include any maf isolate conditions received from other network panels.
7.4.8 CONTROLLING ZONE LEDS
An output logic equation controlling a "module relay" where the relay number is in the range
65 to 256 is used to control a zone LED. F3200 allows a maximum of four 16 zone LED
display boards corresponding to 64 zones. Relay equations with relay numbers 65-128 are
used to control the alarm LEDs 1 to 64. Relay equations with relay numbers 129-192 are
used to control the fault LEDs 1 to 64. Relay equations with relay numbers 193-256 are
used to control the isolate LEDs 1 to 64. Relay numbers 65-256 cannot be used in the "right
hand side" part of an equation as an operand. The LEDs being controlled will be either on
steady or off - they cannot be selected to flash.
It is necessary to ensure that no zone or module relay is mapped to any LED being
controlled by logic (mapping of zones to LEDs is described in section 7.3.3).
