7.2 Repeater Configuration
The panel can be programmed to communicate with
up to 3 repeaters. Repeaters can only be used with
4-zone & 8-zone panels.
7.2.1 Repeater selection
When the Repeater configuration DIL switch (Rep
Config) is switched to the ON position, the panel
sounds the internal buzzer and illuminates the
SYSTEM FAULT LED to indicate that the
programming mode has been initiated. The current
status of the repeater configuration is also displayed
on the Repeater Fault LEDs, which are visible
when the front cover is removed.
Operation of the Select button will increment the
number of repeaters, up to a maximum of 3, after
which the number is reset to zero.
Once the required quantity of repeaters has been
configured and the configuration DIL switch is
returned to the OFF position, the panel will return
to normal operation.
The programming information is stored in
EEPROM and is not lost during power-down of the
panel.
NOTE: Do not connect & configure repeaters
until the panel has been commissioned.
7.3 Invalid Configuration conditions:
An invalid programming condition will exist if
both DIL switch 4 & 9 are in the ON position at
the same time. In this case:
o The System Fault LED will flash.
o The fault relay will operate.
o The panel buzzer will sound.
o The Cursor indication will clear.
o Configuration will be inhibited.
To clear the invalid condition, return both DIL
switch 4 & 9 to the OFF position.
7.4 Zone 1 Non-latch operation
The Zone 1 non-latch DIL switch allows zone 1 to
be set to non-latching fire indication.
In this mode a fire condition on zone 1 operates the
sounders but not the Auxiliary Fire Relay. The
alarm indication automatically clears when the fire
condition is removed from zone 1, without the need
to manually reset the panel.
7.5 Resistor EOL
The Resistor EOL DIL switch configures all zones
to monitor an end-of-line resistor (6K8 to 3K9)
instead of the default 10uF capacitor.
Ensure no detector bases have diodes fitted if using
this mode.
NOTE: This facility is not available on the twin-
wire panel.
Resistor EOL monitoring is provided for older
installations where it is impractical to change the
EOL resistor for a capacitor.
Detector/MCP discrimination will not work
when the zone monitoring is configured for
Resistor EOL and therefore zone alarm
dependency (coincidence detection) and Alert
Mode will not work correctly.
7.6 Alert Mode
The Alert Mode DIL switch configures all zones to
discriminate between detector alarms and MCP
alarms. Detector Alarms are treated as Alert; MCP
alarms are treated as Evacuate.
The Sounders are pulsed (1 second on, 1 second
off) during the Alert alarm and operate
continuously during the Evacuate alarm.
When used in conjunction with Zonal Sounder
operation, a detector alarm will only pulse the
relevant zonal sounder circuit with all other sounder
circuits silent. A MCP alarm will operate the
relevant zonal sounder circuit continuously and
pulse all other sounder circuits.
On the display, the left zonal fire LED operates for
detector alarms, the right zonal fire LED operates
for MCP alarms.
NOTE:
It is recommended that TYCO CP211 call points
are used on zones with Twin-Wire sounders in
order to reduce the zone load when more than
one call point is operated. You can use call
points with 360R resistor fitted as an alternative
but operation of more than one call point will
increase the zone load and may prevent the
Twin-Wire sounders from operating correctly.
If Twin-Wire sounders are not being used then
the TYCO CP211 or MCP with resistor may be
used (MCP resistor needs to be 220R to 360R).
Manual call points with 470R to 1K will be
indicated as a detector alarm instead of a MCP
alarm.
Alert mode will not work correctly with Resistor
EOL due to the inability to correctly
discriminate between detectors and MCPs when
EOL resistors are used.
