2.2.1 PSU/Common Services Card
• The PSU/Common Services Card is located in the right hand card slot of the
enclosure, (Position 0), when viewed from the front.
• As PSU/Common Service cards can be powered from 85-263VAC 50/60 Hz
or 88 to 300VDC for safety reasons please ensure the supply is fully isolated
before removing the associated card.
• Single and Dual redundant power supply options are available providing
secure power to the panel. For further information please see pages 17
and 18
2.2.2 Alarm Cards (8 Channel)
• Alarm cards are located to the left of the PSU/Common Service card.
• On 16, 24 and 32 way versions multiple alarm cards are used.
• The alarm cards are interchangeable however as the associated
conguration settings are stored on the individual cards if a card is placed in
the incorrect slot the setting may not match the monitored process.
• The PSU/Common Services card and Alarm card are polarised to prevent
insertion into the incorrect card slot.
2.2.3 Pluggable LED’s
Each channel is illuminated by a pluggable LED located on the front of each 8 channel
alarm card.
The LED assembly is held in place by 2 pins and the assembly can be removed by pulling gently
towards you.
LED assemblies are available in the following colours:-
• White .........(WT). • Red ............(RD).
• Yellow ........(YW). • Green .........(GN).
• Blue ............(BL). • Intermixed …….(I).
(Specify colour required per channel).
WARNING !
Hazardous voltages may exist on the LED assembly connections accessed via
the frtont panel.Take care and use insulated tools to remove and replace
LED assemblies

2.2.4 Input Isolation
All signal inputs are optically isolated for use in harsh electrical environments.
2.2.5 Bi-Polar Inputs
125v and 250v signal inputs are bi-polar and therefore capable of accepting AC or DC
voltages. 24 V and 48V are DC input only
2.2.6 Standard Input Version
The standard version uses a fully isolated +24VDC supply as a signal voltage, (fused
at 160mA), which can be fed via a normally open (N/O) or normally closed (N/C) eld
contact to trigger each alarm as required.
2.2.7 Optional Powered Input Versions
As an alternative Customer powered Inputs can be used:-
• Option A = 24VDC & 125VAC/DC or
• Option B = 48VDC & 250VAC/DC.
The signal supply voltage level must be specied at the time of order to ensure the
correct type alarm card is supplied.
2.2.8 Integral Pushbuttons
Four Integral tactile pushbuttons are provided as standard designated as Test, Mute, Ack,
(Acknowledge), and Reset.
2.2.9 Customer Terminals
Industry standard rising clamp terminals capable of accepting up to 2.5mm2 cable are
provided for customer use on the rear of the annunciator and each terminal is held
in place by retaining screws located at the top and bottom of each terminal block for
additional security.
WARNING !
Hazardous voltages may exist on the rear panel connections when connectors are
removed.Take care not to touch any exposed parts

2.2.10 Terminals For Use With External Pushbutton Inputs
Five additional optically coupled inputs , PB1 to PB5, are available on the rear of the
annunciator for use with external pushbuttons, group inhibit or a sleep mode switch as
required.
The common return for the remote inputs is PCom
Please note: VAUX +24V can be used for external pushbuttons, or any nominal 24V
terminal on the rear panel.
WARNING !
Hazardous voltages may be present when the front panel is removed.
Take care not to youch exposed parts on the annunciator beyond those

2.2.11 Internal Audible Alarm
An integrally mounted 2.4Khz speaker is located on the common services card.
To adjust to volume use the slider in the SmartAlarm congurator as shown below.
2.2.12 HNA & HNB Horn Relays
Common Relay – HNA & HNB are used as Horn Relays and the following options are
software selectable:-
• Any channel within the annunciator can be set to operate either relay as required.
• The relay coil state can be set to Normally Energised or Normally De-Energised.
• The relay can be disabled to prevent it operating on System Test.
• The relay can be disabled to prevent it operating during Sleep Mode.
• Relay mode is set to horn as default but can be modied to other modes using the
conguration software.
2.2.13 GPA & GPB Common Alarm Group Relays
Common Relay – GPA & GPB are used as Group Relays and the following options are
software selectable:-
• Any channel within the annunciator can be set to a common alarm group.
• The group function can be set to “alarm” which keeps the signal active until the
alarm has been cleared.
• Any “alarm” group within the annunciator can be linked to either relay as required.
• A reash function can be selected per group which allows the contacts to revert
to normal and re-alarm each time a new alarm occurs within the same group. The
reash pulse duration can be set between 1mS and 65,000mS.
• The relay state can be set to Normally Open or Normally Closed.
• The relay can be disabled to prevent it operating on System Test.
• The relay can be disabled to prevent it operating during Sleep Mode.
• Relay mode is set to group as default but can be modied to other modes using
the conguration software.

2.2.14 WD Watchdog Relay
A Watchdog Relay is available as standard to provide a signal to a 3rd party device to
indicate a fault has been detected within the annunciator. The following options can be
congured in software.
• All faults.
• Field contact fault.
• System fault.
• Comm’s fault.
• Card fault.

2.2.15 Watchdog Monitoring LED’s
As alarm annunciators are used in safety critical applications it is important that the
functions of the annunciator are monitored and the SmartAlarm is equipped with an
extensive self-diagnostic facility including two green status LED’s, in standard mode they
provide dynamic monitoring of the logic supply, eld contact supply, and system status.
In diagnostic / program mode the LED’s allow real time contact status monitoring,
manual input type programming and communications Tx & Rx monitoring.

DRAFT - 09 June 2021 DRAFT - 09 June 2021
2.2.16 Diagnostic / Program mode - Dynamic Contact Status
The internal pushbuttons can be used to view the dynamic state of all signal inputs by
pressing and holding the internal Test pushbutton for 10 seconds.
LED-1, located above the test pushbutton, slow ashes to indicate the Annunciator is in
monitor mode.
Whilst in this mode the individual channel LED provides the dynamic status of the
associated eld contacts.
• If the LED is ON the eld contact is CLOSED.
• If the LED is OFF the eld contact is OPEN.
This is a quick method of verifying the dynamic state of the eld contact and is typically
used during commissioning or fault nding.
The contact monitoring function times out after 1 minute and the unit automatically
returns to the normal run mode and LED-1 reverts to steady ON.

2.2.17 Diagnostic / Program mode - Manually changing the input type
The internal pushbuttons can be used to change the input state for each channel
from normally open (N/O) to normally closed (N/C) by pressing and holding the
internal Test pushbutton for 10 seconds.
LED-1, located above the test pushbutton, slow ashes to indicate the Annunciator
is in the monitor mode.
Press the Mute pushbutton once and note LED-2 and Channel-1 LED slow ash to
indicate that you are now able to invert the state of Channel-1 as required.
Pressing the Ack. pushbutton navigates to the next channel in sequence and once
the last channel has been congured the cycle repeats.
Pressing the Reset pushbutton toggles between N/O or N/C
Note: As you navigate away from each channel .
• If the LED remains ON the input is set to normally closed .
• If the LED is OFF the input is set to normally open .
The “input state function” times out and the unit automatically returns to the normal
run mode after 1 minute and LED-1 reverts to steady ON.

The internal pushbuttons can be used to monitor communication activity between the SmartAlarm
and 3rd Party devices by pressing and holding the internal Test pushbutton for 10 seconds.
LED-1, located above the test pushbutton, slow ashes to indicate the Annunciator is in monitor
mode.
Press the Mute pushbutton twice and note LED-1 and LED-2 go OFF and then act as Rx & Tx for
communication between devices.
The communication monitoring function times out and the unit automatically returns to the normal
run mode after 1 minute and LED-1 reverts to steady ON.
