operation of the Manual Fire Alarm/Muster
button on the panel display causes all sounders
to operate continuously until the silence alarms
switch is operated. Manual Fire Alarm/Muster
Alarm will also override the sounder delay and
activate all sounder outputs.
• In Muster-mode, operation of the Manual Fire
Alarm/Muster button on the panel display
causes all sounders to operate in the
internationally recognised muster mode [7 short
pulses followed by one long pulse, repeated].
This will continue until the Silence Alarms button
is pressed.
• If Muster and Manual Fire Alarm modes are
disabled, the manual fire alarm/muster switch is
not functional. This feature is provided to avoid
duplication and operator confusion in instances
where a totally separate manual muster system
is provided.
All three modes (Muster, Manual Fire Alarm, and
Disabled) are selected by a single link [J2] on the
rear of the display PCB. [Note: The link is clearly
labelled – “Muster enabled/Evac enabled”. Evac
= Manual Fire Alarm]. The link is removed for the
Disabled condition.
The user control insert fitted to the display is
double-sided to allow the installer to label the
Manual Fire Alarm/Muster button according to the
panel configuration. On the front side, the top left-
hand button is labelled “Manual Fire Alarm” and on
the reverse side it is labelled “Muster”. A blank is
provided for use when the Manual Fire
Alarm/Muster feature is disabled.
17.13 Inhibit Fire Protection on Non-
Latched Zone DIL Switch
DIL switch SW1/1 configures the Fire Protection
output relay on the motherboard [and any
expansion outputs selected to the fire protection
type] to operate or not to operate for a fire condition
on any zone configured to non-latched mode. This
feature has been provided to allow two panels to be
linked so that a fire condition on one panel triggers
a fire on a zone on the other panel [and vice versa]
without latching up. It can also be used to prevent a
fire signal from a remote panel tripping any fire
protection equipment connected to the local panel
via the expansion outputs. The zones used to
monitor the fire signals from remote panels should
be configured to non-latching and the Fire
Protection relay on the motherboard should be
used to transmit a local fire signal to the remote
panels.
17.14 Delay Alarm Silence and Reset
Controls DIL Switch
DIL switch SW1/2 prevents the alarms being
silenced and panel reset for a period of 3 minutes
after a fire alarm condition occurs. (Not applicable
to Muster Alarm).
17.15 Delay ON Auto DIL Switch
DIL switch SW1/3 has been re-assigned to enable
zone coincidence for use with the Watermist
extinguishing panel. This switch should be left in
the OFF position for normal operation. When the
switch is in the ON position, the Fire Protection
outputs on the optional output expansion system
will operate in pairs as required by the Watermist
system.
17.16 Alarms on Evac Only DIL Switch
DIL switch SW1/10 configures the sounders to
operate only
when the panel is in Manual Fire
Alarm or muster activated condition.
17.17 Silence before Reset DIL Switch
DIL switch SW2/1 determines when the panel can
be reset from the fire condition:
OFF: Reset from Fire is available when panel is in
the fire condition and sounders are active or
silenced.
ON: Reset from Fire is available only after the
sounders have been silenced.
17.18 Continuous or Pulsed Sounder
Operation DIL Switch
DIL switch SW2/2 selects all sounders to operate in
either continuous or pulsed mode.
17.19 Silent Zone Test DIL Switch
DIL switch SW2/8 selects the type of sounder
response in One Man [Detector] Test Mode:
OFF: Normal sounder response [continuous or
pulsed in line with panel configuration]
ON: Silent [no sounder operation]
17.20 Buzzer Disable DIL Switch
DIL switch SW2/9 enables/disables the panel
fire/fault buzzer and gives a DISABLED indication
on the display.
17.21 Latched Faults DIL Switch
DIL switch SW2/10 enables/disables the latched
fault indication mode. When enabled, all fault
indications latch until the Reset button is operated.
Note: A latched zone fault will be cleared if a fire
condition occurs on the same zone.
17.22 Repeater Configuration
Three DIL switches on the optional Repeater
Interface board allow the engineer to configure the
panel to communicate with up to 5 remote
indication panels via the RS485 serial data link.
17.23 Output Relay Configuration
The Fire Signal Output, Fire Protection and Fault
output relays are link-configurable on the panel
motherboard to provide one of the following
