7.4. Access to the Explosionproof Enclosure
Fig 2: Accessing the enclosure
On completion of the installation the flameproof threaded joint should
be inspected to ensure that they are clean and that they have not been
damaged during installation.
Ensure the O-ring seal is in place and undamaged.
When fitting the flameproof cover ensure the thread is engaged
correctly. Fully tighten the cover all the way, ensure no gap is visible
between the cover and base of the sounder enclosure.
8) Installation Requirements
8.1. Safe Installation Requirements
Warning High voltage may be
present, risk of electric shock.
DO NOT open when energised,
disconnect power before opening.
The sounder must only be installed by suitably qualified personnel in
accordance with the latest issues of the relevant standards.
8.2. Cable Selection and Connections
Electrical connections are to be made into the terminal blocks on the
PCBA, using solid wire 0.5-4mm2 / AWG 20-12 or stranded wire, sizes
0.5-2.5mm2 / AWG 24-14. Wire insulation needs to be stripped 8mm.
Wires may be fitted securely with crimped ferrules. Terminal screws
need to be tightened down with a tightening torque of 0.45 Nm / 3.5
Lb-in.
When selecting the cable size, consideration must be given to the input
current that each unit draws (see table 1), the number of sounders on
the line and the length of the cable runs. The cable size selected must
have the necessary capacity to provide the input current to all the
sounders connected to the line.
DC: 0.2 - 2.5mm2/ AWG24 - AWG12
Fig 3: Wire Preparation.
When connecting wires to the terminals great care should be taken to
dress the wires so that when the cover is inserted into the chamber
the wires do not exert excess pressure on the terminal blocks. This is
particularly important when using cables with large cross-sectional
areas such as 2.5mm².
8.3. Earthing
Fig. 4 Earth Locations
Internal earthing connections should be made to the Internal Earth
terminal in the base of the housing using a ring crimp terminal to
secure the earth conductor under the earth clamp. The earth
conductor should be at least equal in size and rating to the incoming
power conductors but at least a mini mum of 0.82mm2 / 18AWG in
size.

12) SIL 2 Instruction/Safety Manual
Figure 9 - The SIL 2 Module monitors the Sounder and interfaces to the customer plant.
Warning To maintain the integrity of the SIL 2 units the system must be installed, commissioned and used within the parameters outlined in this
manual. Failure to comply could result in an unintended unit operation or function.
Warning The unit must be powered in either Standby or Active modes to comply with the SIL 2 approval requirement.
If the power is disrupted the unit must be allowed to go through the commissioning cycle to reset.
Failure to complete the commissioning cycle and continued disruption in the power supply will generate a fault state which will require
the sounder to be reset (see section 16-4).
Warning Only the alarm tones specified in section 15 may be selected for use in SIL2 compliant systems.
SIL 2 System Description
The SIL 2 module monitors the function of the device and provides
feedback to the control panel. A fault condition can be communicated
by two methods:
•4 wire installation can be seen as per section 16-1.
A SIL 2 system wiring for fault detection in standby and
active mode with independent fault contacts.
•2 wire installation can be seen as per section 16-2.
A SIL 2 system by the introduction to the monitoring circuit
and linking in an end of line resistor can only register the
fault in standby mode.
13) SIL 2 System Terms and Function
The SIL 2 Sounder Unit Monitors
•Standby mode and Active mode
•Health status of power supply
•Sounder correct function and tone pattern
The SIL 2 sounder operates as part of a SIL 2 system.
The sounder will after commissioning remain powered in Standby
mode (reverse polarity) until the sounder is required to operate. When
the signaling device is required to operate the polarity is changed to
normal supply and the sounder will go into Active mode where it will
start to sound the correct tone. When periodically testing the system
and sounders operation is put into Active mode.
The system panel or PLC will control whether the system is in either
of the main two operational modes.
Standby Mode This is where the power supply polarity is reversed
so negative (ve) is feed to the positive (+) sounder terminal and
positive (+) is feed to the negative (ve) sounder terminal.
In Standby mode the sounder will not sound the tone but the SIL 2 unit
is monitoring power supply and is set-up ready to go to Active (alarm)
mode.
Power relay RLY1-1 will be open whilst SIL 2 relay RLY1-2 will be
closed contact between terminals 1 & 2.
If power is disrupted the SIL 2 unit will go into Fault mode, in fault
mode the Power relay RLY1-1 will close whilst SIL 2 relay RLY1-2 will
become open circuit between terminals 1 & 2.
Active Mode This is where the power is in normal polarity, positive
(+) supplied to the positive (+) sounder terminal and negative (ve) is
supplied to the negative (ve) sounder terminal.
In Active mode the alarm horn sounder will output the selected alarm
tone. The SIL 2 module checks for the correct alarm tone output and
the functionality of the alarm tone signal generation process.
Power relay RLY1-1 will be open whilst SIL 2 relay RLY1-2 will be
closed contact between terminals 1 & 2.
The SIL 2 unit will also check for signal polarity.
If a fault is found the SIL 2 unit will go into Fault mode.
If power is disrupted the SIL 2 unit will go into Fault mode, in fault
mode the Power relay RLY1-1 will close whilst SIL 2 relay RLY1-2 will
become open be circuit between terminals 1 & 2.

SIL 2 unit change the state for relays RLY1-1 and RLY1-2.
In fault mode the Power relay RLY1-1 will close whilst SIL 2 relay
RLY1-2 will become open circuit between terminals 1 & 2.
13-1 Sounder Failure
•Tone Failure No Tone detected
•Sounder Controller failure No tone generation pulse
detected
•Tone Rate Failure Regular tone cycle erratic
13-2 Power Failure / SIL 2 Failure
•SIL 2 Controller failure Internal function and system
checking flags fault
•Rapid Power cycling System indicates power instability
•Total Power Failure
It is possible to reset these faults if they were transitory.
Resetting Failure (by power cycling) - It is possible that the SIL 2 unit
can be reset by powering the unit off for a period greater than 20
seconds. On restarting the unit and running through the
commissioning cycle the fault may clear.
Resetting Failure (by Hard Reset) - It is possible that the SIL 2 unit can
be reset by hard resetting the unit using the reset jumper within the
unit (see section 16-4) on hard resetting.
On restarting the unit and running through the commissioning cycle,
the fault may clear. It is necessary to run the test function cycle again
to see if the fault is still evident.
If the hard reset process does not correct the latched fault the alarm
horn sounder may require further investigation, please contact your
local E2S representative.
Commissioning System - Functional start-up of System
(Normally in reverse polarity mode)
When Commissioning system the power must not be disrupted to the
5 seconds.
Once past this period the SIL 2 system is fully operational and will be
in monitoring the sounder and power in Standby mode.
The relay RLY1-2 on the SIL 2 unit will only remain open for a
maximum of 1 second on commissioning start-up. RLY1-2 will
subsequently close contacts 1 & 2 indicating healthy operation.
Contact 1 & 2 will only remain open in the event of a fault or a loss of
power.
System Testing (Active Mode normal polarity)
The SIL 2 system will remain monitoring the power in standby mode
until the polarity is changed to normal mode to enable an active system
for sounder functional testing.
Important: - The polarity must be held in active mode for a period in
excess of 15 seconds to ensure a full system check is performed.
Once the test period has been completed the unit can be switched
back to standby mode by reversing the polarity.
If no faults have been found during the test the relays will remain in
steady state.
The SIL 2 unit will continue to monitor the power and module function.
Important: - The automated test cycle must be undertaken on at least
a weekly basis to maintain the SIL 2 units reliability.
System Activation (Active Mode normal polarity)
The SIL 2 system will remain monitoring the power in standby mode
until the polarity is changed to Active mode to enable an active system
for sounder to function as a warning signaling device.
Important :- The polarity must be held in active mode for a period in
excess of 15 seconds to ensure a full system check is performed whilst
in alarm mode, although it is expected that during a system activation
this period will be significantly greater.
Note :- The fault indication signal on TB1 can take up to 50
milliseconds to indicate system fault.

16-1) SIL 2 system wiring for fault detection in standby and active mode –4 wire installation
(Recommended)
The customer is required to wire into both the sounder power supply terminals block and also the SIL 2 Relay terminals TB1
The power supply terminals only need to have the supply power connected. This will be reverse polarity for monitoring mode and normal polarity for
active mode. There is no need to fit an EOL resistor on the power supply terminal block as the TB1 is configured to raise a fault alarm in any situation.
Terminal block TB1 is the output from the SIL 2 monitoring relay. Relay RLY 1-2 provides a closed circuit between TB1 terminals 1 & 2 whilst powered.
On detection of a fault event this will become open circuit.
The fault will be seen via the SIL 2 TB1 terminals as soon as the fault occurs in either Active or Standby modes.
When no fault is detected the circuit to the SIL 2 TB1 terminals 1 & 2 will include a factory fitted 3.3K Ohm current sense resistor (CSR) in series. When
the circuit is driven with 24Vdc the detection current seen is ~7.3mA @ 24V.
The only other fault mode is if the cable goes short circuit where a short will be seen by the panel.
Option: Should the fault event output of RLY1-2 be required to operate as a switch, header J1 can be set to link pins 1 & 2 (see figure 11) thereby
removing the 3.3k Ohm current sense resistor (CSR) from the circuit.
Note: a cable short circuit will not be detectable in this configuration.

If multiple SIL 2 alarm horn sounders are to be cabled in series the monitoring connections differ from that of a single alarm horn sounder. For more
information see manual D197-00-651-IS available from the E2S website.
16-2) SIL 2 system wiring for fault detection in standby mode only –2 wire installation
Cabling is required to the positive '+' and negative '-' power input terminals only. Monitoring will occur in standby mode only whilst power supply polarity
is reversed. An EOL resistor may be added during installation or can be factory fitted. See Table 5 for EOL resistor value guidance.
The SIL2 monitoring module contains a factory fitted Power Supply Fault Resistor 2.2K Ohm (FR). When a fault is detected the Fault Resistor will
activated. The total measurable resistance of the EOL resistor and Fault Resistor across the power terminals which already has customer EOL resistor
n Standby Mode.
Important: - The 2 wire configuration will not warn of a fault whilst in Active mode. A fault will only be detectable in standby mode when power supply
polarity is reversed.
Important: - The 2-wire configuration requires the J2 header pin to be set to position B (see figure 14). Factory default position is A.

To evaluate the total current drawn from the SIL 2 unit, use the equation below.
In standby mode, where there is no fault, RLY 1-1 is open. This means the voltage only passes through the customer EOL resistor and the current
drawn from the SIL 2 board is 25mA. Therefore, the equation for a No Fault scenario is then:
In standby mode, where there is a fault, the circuit is closed. This means the voltage passes through both the customer EOL resistor and current sense
resistor and the current drawn from the SIL 2 board is 20mA. The customer must first calculate the resistance of the two resistors in parallel before
applying the currents to the equation. The equation for a Fault scenario is then:

20) Product Coding for Fault Resistor and Customer EOL Resistor
The customer is able to identify the resistor values chosen on purchase from the product code.
This is represented by the last three characters:
D1xS2FDC024AB1S1R-AFZ
•The first A character denotes the value of the Fault Resistor (FR) Default value is 2.2 kunless an alternative value is requested
when ordering.
•The second F character denotes the value of the Current Sense Resistor (CSR) Default value is 3.3 k
value is requested when ordering.
•The third Z character denotes the value of the unit End Of Line Resistor (EOL) By default no EOL is fitted (Code = Z) A factory fitted EOL
resistor can be specified when ordering.
The values of resistors available are shown in table 7 below.

Note: To utilise the full monitoring functionality the 4-wire configuration is recommended. An EOL resistor is not required for this configuration.
The alternative 2-wire configuration requires an EOL resistor to be fitted. The EOL resistor can be specified during ordering and factory fitted or selected
and fitted during the alarm horn sounder installation.
See section 9 for EOL resistor location and wattage requirements. E2S recommends a value of 2.2K Ohm. If an alternative value is required, please
see section 16-2.
Both the (FR) Fault Resistor and (CSR) Current Sense Resistor are factory fitted and cannot be user replaced.
