Fire Extinction

• Some models of the Previdia Micro control panel allow the management of a gas-extinguishing channel.
• Complies with EN12094-1 and provides the inputs, outputs and control logic required by these systems.

The following figure shows a flowchart of the operations carried out by the control panel in the pre-extinction phase, that is, from the occurrence of the events that trigger the extinction phase to the start of the release condition, and during the release of fire extinguishing gas:

The following table contains a description of the functions associated with the extinction that can be programmed for the control panel inputs and outputs.

the cylinders. During standby status, its activation generates a fault warning.
Confirm release from pressure switch|

Input, for the connection of a pressure switch, confirms the release of the gas from the cylinders.

|

After releasing the electro valve, its activation is used to confirm the release of the gas.

Flow switch

| Input, for the connection of a flow sensor that will signal the release of the gas from the cylinders.| The input will be activated by a sensor that detects the flow of extinguishing gas. The flow may have been activated directly without following the procedure of extinction and pre-extinction.

Stop extinction

|

The inputs stop the extinction procedure by the activation mode described opposite.

|

Abort

| If this input is activated during the pre-extinction phase, the extinction procedure will be aborted even if the input resets. The procedure can be restarted only after the control panel is reset. If this input is activated during standby, it will generate a fault warning.

Add

| If this input is activated during pre-extinction status, the extinction procedure will remain locked until the input resets. On input reset, the pre- extinction countdown will refresh and restart.

If this input is activated during standby, it will generate a fault warning.

Hold

| If activated during a pre-extinction condition, the extinction procedure is stopped but the pre-extinction time count continues. When the input is restored, if the pre-extinction time count has terminated, the gas will be released.

If this input is activated during standby, it will generate a fault warning.

External

| This function is identical to the “Hold” function but refers to mechanical or electrical intervention (for example, a door contact that inhibits gas discharge, etc.).

This activation will be signalled separately.

If activated during standby, it will not generate a fault warning.

Manual extinction| This input is for the connection of one or more manual call points for the activation of extinguishing-agent discharge.|

Electrovalve

| Output for the connection of the electrovalve which discharges the extinguishing agent.|

It will activate only when the pre-extinction time expires

Stop extinction active|

Output for the connection of stop-extinction signalling devices.

|

It will activate when the extinction channel is stopped by one or more inputs connected to the “Stop extinction” input.

Pre- Extinction| Output for the connection of a signal relating to the imminent discharge of the extinguishing agent.| It will activate during the pre-extinction time which runs before the discharge of the extinguishing agent.

Release

| Output for the connection of signalling devices that warn building inhabitants of the actual discharge of the extinguishing agent.|

It will activate on activation of the electro valve.

EN12094- 1: To guarantee compliance of the product to EN 12094-1, the control panel must be configured to make available the following functions (the others are optional):
Manual extinction, Electrovalve, Pre-extinction, Release.

The “Electrovalve” function must only be associated with the “AUX” terminal on board the control panel.
Refer to the Configuration Manual for the programming details of the other functions.

EN12094-1: In compliance with the requirements of standard EN 12094-1, if the “Stop extinction-Abort” function is used in a Previdia Micro control panel, the “Stop Extinction-Hold” and “Stop Extinction-Add” functions cannot be activated, and vice versa.
Please remember that no more than 32 devices can be connected to each of the selected input or output terminals.

2. Crimp the earth line wire to the eyelet terminal [B].

3. Attach the wire with the eyelet to the control panel using the ground connection screw [C].

4. Ensure that the terminal “ ” of the power supply module [D]], the motherboard [E] and the front plate [F] of the cabinet are connected to the earth system. Attention: The protective earthing system must be compliant with the local safety regulations, fire codes, laws and bylaws in force.
   Note: A protective earth connection ensures that all exposed conductive surfaces are at the same electrical potential as the earth surface, to avoid the risk of electrical shock if a person touches a device in which an insulation fault has occurred. In the event of an insulation fault, a protective earth connection will generate a high fault current which in turn will trigger an overcurrent protection device (fuse) and disconnect the power supply.

5. Ensure that low-current safety or signal lines DO NOT come into contact with points with potentially dangerous currents.
   Using a plastic cable tie, bunch the wires together and secure them to one of the wire hooks on the back of the cabinet [G].
   Note: The connection wires (to the mains supply and also any other wires inside the cabinet) must be secured to the cable hooks on the back plate using plastic cable ties. Use a cable with double isolation for the connection to the electrical mains.

Connecting the batteries
The metal cabinet of the control panel provides housing for two 12V, 7 Ah lead batteries for the small version and 17 Ah for the large version. The two batteries must be connected in series, in such a way as to supply 24V.
The backup power batteries are not included.

1. Insert the batteries into the battery compartment inside the cabinet (paragraph 2.2 – [B1]).
2. Using the battery wire ([A]), connect the batteries.
3. Connect the wire coming from the power supply ([B] paragraph 2.2 – [V]) to the battery terminals ([C]).

Attention: Ensure that the polarity is correct.

• Red – Positive
• Black – negative

The connection of the batteries before the mains voltage is present will not activate the system. Once the mains voltage is supplied, the power-supply module will connect the batteries automatically and initialize the circuits that manage them.
Position the thermal probe (paragraph 2.2 – [W]).
The thermal probe must be positioned on the side of the battery and held in place by a strip of tape ([D]).
Note: The installer must use only valve-regulated lead-acid batteries (VRLA) for stationary use, compliant with IEC 60896-21 and IEC 60896-22 standards. Such batteries must have a V-1 or higher firestop casing. For the internal clock battery replacement, the installer must use only non- rechargeable CR2032 lithium batteries compliant with IEC 60086-4 standard.

• The wiring diagram illustrates a connection to be made to one of the
• Tx terminals are configured as an input which is connected to a generic device with 100mA maximum output powered from a 24V source, in the diagram the control panel AUX terminals.

Connection of polarized devices (sounders, etc.) to channels configured as outputs

The polarities refer to the active status of the output, the polarities invert for stand-by status.
EN54: If the control panel default settings are left unchanged, the I/O 1 output will result in being configured as a type C output for the connection of audible/visual signalling devices. The output will activate in the event of any type of fire alarm condition.

Connection of non-polarized devices (relays, etc.) to channels configured as outputs

Relay output wiring
Cables: 2/3 wire shielded cable Proper section (minimum 0.5mm², maximum 2.5 mm²) Compliant with local laws and regulations in force
The relay output of the module (terminals “28-29-30”) must be connected according to the following diagram:

• All voltage-free relay contact can only be connected to SELV circuits.
• The illustrated connection does not supervise the cable and does not signal connection faults.

EN54: If the control panel default settings are left unchanged, the RELAY output will result in being configured as a fault signalling output.

• In compliance with the regulations in force, the output must be configured as “inverted” to switch to fault conditions when the system is completely without power.
• Therefore, in stand-by status, (no faults present on the system) terminals C and NO will be closed, whereas terminals C and NC will be open.

Connecting the Hornet+ network
The connection of two or more control panels (Previdia Max, Previdia Micro or repeaters) in a Hornet+ network can be achieved by using two RS485 communication ports.

Cables: 4 wire shielded cable Typical impedance 12Ohm

• Maximum length 1000m (between two successive control panels)
• Compliant with local laws and regulations in force

Connecting the land-line (PSTN)
The control panel can only be connected via the optional Previdia-C-DIAL board.

Cables: Compliant with local regulations in force

Connect the telephone line [A] to the “L.E.” terminals and telephone device or the internal phone line [B] to the “L.I.” terminals of the board ([C], paragraph 2.4 – [B]).

Wiring external communicators
The Previdia Micro control panels can be used to drive remote alarms or fault signalling devices.

Cables: 2-wire shielded cable

• Proper section (minimum 0.5mm², maximum 2.5 mm²)
• Compliant with local laws and regulations in force

The “I/O” terminals onboard the control panel [A] and the supervised outputs can be used to create an E-type output (output for the activation of alarm status signalling on a remote signalling device, as prescribed by standard EN54-2).

To create a J-type output (output for activation of fault status signalling on a remote signalling device, as prescribed by standard EN54-2), only the “I/O” terminals can be used on board the control unit, which can be Programmed as active in rest condition.

EN54: In both cases, as the external communicator, you must use a remote communication device compliant with standard EN54-21 [B] and equipped with a supervised activation input [C], a normally closed fault signal output [D] and a normally open output for confirming successful communications [E]].

If the external Communicator does not have a supervised activation input, the connection to the control panel can be carried out by employing a relay, which must be installed inside the communicator casing. To transmit alarm events via the I/O terminals on board the control panel, you can use normal wiring for non-polarized devices. To transmit failure events, use the following wiring diagram :
