Honeywell GENT S4 Instruction manual

The S4 Mains powered interface units (Part No's:
S4-34440-02 and S4-34440-12) are EN54-4
compliant battery backed power supplies that can
be directly connected to the Vigilon and Nano loop
and also have highly flexible interfacing capability.
The 4 channels can be individually configured to
provide Output and Input interface in various
configuration modes, to control external equipment
and receive input to allow the fire system to make
decisions and take actions. It is now possible to
have combined inputs and outputs giving a total of
8 external circuits connected (e.g. 4 sector outputs
and 4 confirmation inputs). The units have room to
accommodate optional modules on to DIN rails. It
has a configurable auxiliary power output that is
derived from its self contained mains power supply
unit, which is battery backed to continue to deliver
power in the event of mains supply failure.
Note a Nano system loop can only accept S4-34440-02.

Output mode
This is when a channel is configured as an output and the channels input terminals are not used.
Mode settings notes
Output Output type The Sectored output is used to power a wide range of alarm products
such as sounders, bells door holders and relay. A series blocking diode
must be used.
The LED output drive of 1.5mA is available.
The Unmonitored sector output is for use with galvanic isolator, in
this mode no end-of-line resistor or series diode is required.
Unmonitored sector lines will have no associated analogue channels.
The Door release category A option is used for controlling door
release mechanisms that need to meet the requirement of BS7273 Part
4. With Category A the outputs are operated (doors released) from fire,
fault and disablement events.
The Door release category B option is used for controlling door
release mechanisms that need to meet the requirement of BS7273 Part
4. With Category B the outputs are operated (doors released) from fire
events.
Sync. pulse The outputs sends a synchronisation pulse every 10s, the output is
turned off for a short duration. The duration can be programmed to be
approximately 10, 20 or 30ms for compatibility with a wide range of
annunciation devices that require synchronisation such as strobes,
sounders and voice sounders.
Failsafe When On it allows the setting of Fail safe periods for all Mains
powered interface outputs, where outputs are used for fire doors control
applications. When set to 'On' the Initial fail safe period defaults to
120s and the Final fail safe period defaults to disabled. See page 14.
Mains failure To preserve battery capacity for essential functions it is possible to
configure individual outputs to deactivate 'Turn Off' during a mains
power failure.
Output normally This is when a sectored output is configured to work in an inverse
manner. An ON setting will cause the output to turn OFF. Note that in
this mode sector wiring is effectively unmonitored, it is only monitored
when the output is de-energised. This feature may be used with
equipment such as magnetic door holders to ensure the fire door release
once a fire has been detected.

Zone Input mode
This example shows how to set a channel as a Zone input.
Mode settings notes
Zone Input Zone Input Type The Zone Input Type monitors 'conventional' detectors
and call points, with manual call points having 470
ohms resistor in series with Normally Open contacts.
When Gent detectors operate they will draw a constant
current of 30mA. A standard end-of-line capacitor
must be fitted across the Z+ and Z- terminals. Each
zone input can have up to 20 standard detectors
connected with the diode base option.
A Zone Input Type can accommodate a range of
different products to operate at different zone input
thresholds:
Gent (Type 0)
IS Esser Sensor (Type 1)
Apollo/Nittan (Type 2)
Tanlentum Flame (Type 3)
Det-tronics Flame (Type 4)
S/C Fire (Type 5)
Validation Delay The purpose of the alarm Validation Delay is to
minimise false alarms. The alarm validation timeout can
be any value in the range 0 (off) to 37.5 seconds.
During alarm validation delay timeout period the
interface will suppress fire event by applying a reset to
the zone circuit and then wait for a second confirming
fire signal.
Reset Period Other detector types may need a specific Reset period
which can be set here in seconds.

Supervisory Input mode
This example sets the respective channel as a Supervisory input.
Mode settings notes
Supervisory input Input delay The Input Delay is the time before the input is
accepted by the interface, this will filter any noise or
spurious signals, commonly know as "bounce". This
time is the debounce period. The input delay timeout
can be any value in the range 0 to 36 seconds.
Input normally The input channel can be configured to operate with
normally open or normally closed contacts.
Note normally closed operation should be selected if
fail safe contact monitoring is required.

Confirmation Input mode
The purpose of a Confirmation Input is to allow the system to monitor the correct operation of an output,
which relies on external equipment sending back the correct signal. In this mode use a 470ohms end-of-line
resistor with another 470ohms resistor being switched in parallel across the Z+ and Z- terminals to provide
the feedback signal.
Mode settings notes
Confirmation Input Associated output The selected output channel is associated with the
confirmation input channel. Note channel 1 cannot be
selected for associated output as it is already being used
as an output, however this would be possible if the
channel was configured as a combined input/output
channel.
Normal delay The Normal delay is the time before a confirmation
input is accepted by the interface, this will filter any
noise or spurious signals, commonly know as "bounce".
This time is the debounce period.
Confirmation delay This is the delay time before a confirmation input is
accepted by the interface and is how long the interface
waits for a confirmation signal before it brings up a
fault message.
Input normally See page 6.
Input type The verbose setting will generate true/false supervisory
messages whenever the input changes state, as well as
generate timeout fault if the change does not occur
before the delay has elapsed.
The silent setting will only give a timeout fault.

Auxiliary output
The interface has an auxiliary output rated at 1A max. The output voltage can be programmed as
unregulated 24V (+/-3V) on the S4-34440-02 or regulated 12V/24V (+/-0.5V) on the S4-34440-12.
Mode settings notes
Auxiliary
output
When 'On' the auxiliary output is enabled and is disabled when
set to 'Off'.
The “Off” setting should be selected when the auxiliary output is
unused to maximise the battery standby period.
If there is a mains failure then the auxiliary output can be
switched off to preserve battery supply for essential inputs and
outputs.
Option for any equipment that needs a reset pulse to remove a
latched condition, such as a conventional beam that is powered
from the auxiliary terminal and signals a fire condition with relay
contacts connected to a line configured as a switch input.
Select the required output voltage. The 12V option is for
S4-34440-12 Interface unit only.
Fail Safe period settings
The fail safe periods are associated with the all the Mains powered interface units in a standalone system
where Outputs are configured for Door release Category A applications ONLY, see page 4.
Mode settings notes
Initial fail safe period
(seconds)
If there is a fault preventing detection of fire, disablement of fire
detection or other conditions preventing fire detection operation, like
supply failure, then the Outputs will turn 'On' (ie doors released) after
an initial fail safe period of 120s (default).
Final fail safe period
(minutes)
If there are three fail safe conditions that occur within a period set
here then the Outputs are latched 'On' (ie doors released) and can only
be reset by powering down the interface and then powering it up
again. This final fail safe period can be disabled by selecting the
'Disabled' setting, which is a default setting.
