17.7 The Delay Mode Feature
NOTE: This feature does not fully comply with
the requirements of EN54-2.
Outputs can be configured to be delayed in
response to an automatic fire detector operating on
any zone:
i) Overall delay length – fixed at 2 minutes.
ii) Single-Stage (2-stage Delay DIL switch is
disabled).
iii) Output Circuits to be delayed – configured as
described in 17.3.
Operation of an automatic fire detector will raise the
fire alarm indication audibly and visibly on the
panel, operate any non-delayed outputs and start
the time delay function for any delayed outputs.
The delay can be overridden, causing all outputs to
operate immediately, by any of the following
means:
• Operation of a manual call point on any zone.
• Operation of the Delay Override button on the
panel or repeater.
• Pressing the Manual Fire Alarm/Muster button
on the fire alarm panel or repeater. [Operates
the sounders only - does not override other
outputs].
17.7.1 Selection of Outputs to be
Delayed
See section 17.3 for details.
The factory default is no outputs selected for delay
(CREW mode is disabled).
The delay configuration status of the outputs can be
checked on the display by unlocking the controls
and pressing and holding the Disable button.
Outputs selected to the delay mode will provide the
disabled [steady] indication on the Fire Protection
Fault/Disabled, Fire Output Fault/Disabled, Sounder
Fault/Disabled LEDs (Sounder Delay not indicated
in CREW mode). The indication clears when the
Disable button is released.
17.8 Selectable Zonal or General
Alarm Sounder operation
The Zonal Alarms DIL switch selects the sounders
to either:
a) General Alarm Mode [all sounders operate for
any fire condition] or
b) Zonal Alarm [in conjunction with the Pulse Non-
Alarm Zones switch – see section 17.9]
The four standard sounder circuits on the 4-zone
panel can be used in General or Zonal modes. On
the 16 and 32-zone panels, these sounder outputs
always operate in the General mode regardless of
the setting on the general/zonal alarms
configuration DIL switch. The optional output
expansion system [see 4.2.8 above] provides
additional sounder circuits for General or Zonal
alarms on the T1216-C and T1232-C panels.
17.9 Pulse Non-Alarm Zones
This DIL switch selects the type of zonal sounder
response to a fire when the Zonal Alarms feature
described above is selected. The two selectable
options are:
a) Zonal sounders for zone(s) in the fire condition
operate continuously until silenced; all others
are silent.
b) Zonal sounders for zone(s) in the fire condition
operate continuously; all other sounders operate
in pulsed mode until silenced.
17.10 Alarms in Crew Areas
If the ZONAL ALARMS switch is OFF and the
PULSE NON-ALARM switch is ON, the Crew Area
Alarm mode is enabled.
When configured to this mode, the activation of an
automatic fire detector or alert manual call point on
any zone (except Machinery Space) operates
standard sounder output 2 (Bridge/Crew area
sounder circuit) and starts a 2 minute delay. At the
end of the delay sounder outputs 1, 3, 4 and any
expansion sounder outputs also operate.
If an automatic fire detector is activated in a zone
configured as Machinery Space, then sounder
circuits 1 & 2 operate immediately (sounder circuit 1
is for machinery space zones).
Operating an Evacuate manual call point overrides
the delay and operates all sounder outputs.
Pressing the Manual Fire Alarm/Muster button
overrides the delay and operates all sounders in
either Manual Fire Alarm or muster mode as
configured.
If the Fire O/P and/or the Fire Protection O/Ps are
also configured for delayed operation they will be
delayed along with the sounder circuits.
17.11 Delay Restart DIL Switch
Applicable only when CREW mode is enabled, DIL
switch SW2/3 (marked DELAY/MINUTES 2):
• DIL switch SW2/3 OFF: If the Sounders are
silenced before the 2-minute delay has ended, a
new fire condition will not restart the delay and
all delayed outputs including all sounders will
operate immediately.
• DIL switch SW2/3 ON: If the Sounders are
silenced before the 2-minute delay has ended, a
new fire condition will restart the 2-minute delay.
17.12 Selectable Muster/Manual Fire
Alarm Sounder operation
All panels can be set up in either of the following
Muster or Manual Fire Alarm Sounder response
modes.
• In the standard Manual Fire Alarm mode,
