3 General information and technical features

3.1 Purpose

3.1.1 ECD is designed to detect the fire in two zones and control the devices for releasing

gas, powder and aerosol extinguishing agents in the fixed fire extinguishing system. ECD was

developed in accordance with the requirements of EN 12094-1:2015 "Fixed firefighting systems.

Components for gas extinguishing systems. Part 1. Requirements and test methods for electric

automatic control and delay devices " and EN 54-2:2003/Amendment No. 1:2012 "Fire detection

and fire alarm systems. Control and indicating equipment".

ECD is designed to control one direction of fire extinguishing.

It is allowed to use the ECD autonomously (in premises for which the current regulatory

documents do not require the FCAP using) or to be connected to the FAS based on FACP "Tiras

PRIME" or AFAS based on FACP "Tiras PRIME A".

The structural diagrams of the connection of the ECD to FCP are shown in Figure 3.1.

3.1.2 ECD is designed to perform the following functions:

a) transmission of extinguishing signal to release equipment:

1) after reception and processing two independent input signals from two zones;

2) after reception and processing signal from FCP;

b) forming of delay of extinguishing signal (pre-discharge-warning time);

The ECD can be supplied from an external power supply source or from the power supply unit

of the FACP.

ECD is manufactured according to class B (DSTU EN 12094-1:2015), in a plastic case with a

protection degree IP30 according to IEC 60529:1989.

ECD is designed for continuous round-the-clock operation in premises with unregulated

climatic conditions. The range of operating temperatures is from -20 to 50 OC. The relative humidity

is no more than 93% at a temperature of 25 OC.

4 ECD operation

4.1 Operation modes (conditions)

- Quiescent (standby) –operating mode when the ECD is not in any of the following modes:

- Pre-activation –operating mode when the ECD received an activation signal from one of

the controlled zones or one signal from the FACP.

- Activation –operating mode when the ECD received activation signals from:

- both controlled zones,

- two zones of FCP Tiras PRIME or two detectors in FACP Tiras PRIME A zone,

- manual release input ("MANUAL RELEASE" button in the ECD front panel).

When the ECD in the "Activation" mode, the evacuation alert starts working in intermittent

mode and the extinguishing delay time (pre-discharge-warning time) counts down (if a delay is

set).

- Release (extinguishing) –the mode after extinguishing delay time has expired. In the

Release mode, an alert about the release of an extinguishing agent is activated and a signal is

transmitted to the extinguishing equipment.

- Release 2 –a special Release mode when the ECD goes under one of the following

conditions:

- after the "Activation" mode, confirmation of the release of the extinguishing agent was

received;

- received a signal about the spontaneous release of an extinguishing agent in the Quiescent

mode.

The signal about the release of an extinguishing agent is sent to the "KП" input (see

clause 4.3.6).

- Manual (Automatic disabled) –when the ECD ignores receiving activation signals from

controlled zones or from the FCP. Activation of the Release mode is possible only by activating

the manual release input or pressing the "MANUAL RELEASE" button (see p. 4.3.4).

- Fault –when a fault of at least one of the controlled functions or controlled circuits is

detected.

- Disabled –the mode when some functions are manually disabled, the ECD does not

process signals from disabled input circuits or does not issue control commands to disabled

outputs.

4.2 General operation algorithm

The general operation algorithm of the ECD is shown on Figure 4.1.

4.3 ECD inputs and outputs

4.3.1 Operational diagram

The ECD operational diagram with the indication of inputs and outputs with their purpose,

is shown in Figure 4.2

Technical features of the ECD inputs and outputs are given in table 3.1.

The algorithms for determining the state of the ECD inputs and outputs depending on the

connected communication lines resistance are given in clause 4.3.2.

Inputs and outputs connection diagrams are given in Appendix A.

Figure 4.2 –The ECD operational diagram

4.3.2 Algorithm for determining the status of the inputs and outputs depending on

the connected lines resistance

The algorithm for determining the status of the controlled inputs and outputs depending

on the value of the resistance of the lines connected to the corresponding inputs is shown in

Figure 4.3 and in Table 4.1.

4.3.3 «Z1» and «Z2» inputs (Fire alarm zones)

Inputs for receiving signals from fire detectors for automatic launch of extinguishing

work according to the "and" algorithm –the ECD goes into activation mode only if both inputs

are active (Fig. 4.4).

If the "РЗ" input is activated during the activation mode (pre-discharge-warning

time countdown), the ECD immediately switches to the Release mode.

Figure 4.4 –Algorithm when activating inputs "Z1" and "Z2"

4.3.4 «РЗ»input (Manual release)

Input for receiving signals from the MRD for manual launch of extinguishing. When the

«РЗ»input is activated in the Quiescent mode, a visual and audible indication of the input

activation appears on the ECD front panel ("MANUAL RELEASE" indicator, Table 4.2).

Note - pressing the "MANUAL RELEASE" button on the ECD front panel is equivalent

to activating the «РЗ»input.

If the input is activated in Quiescent mode, the ECD starts the pre-discharge-warning time

countdown.

The algorithm of the «РЗ»input is shown in fig. 4.5.

Figure 4.5 –The algorithm of the «РЗ»input

Activations of "Z1" and "Z2" inputs and «РЗ»input have the same priority.

4.3.5 «АЗ»input (Emergency abort)

Input for receiving signals from EAD for emergency abort of extinguishing. In the case of

the «АЗ»input fault (or communication line with the EAD fault), the ECD does not go into

Release mode.

Note - pressing the "EMERGENCY ABORT" button on the ECD front panel is

equivalent to activating the «АЗ» input.

The algorithm of the «АЗ»login is shown in Fig. 4.6.

When activating the «АЗ»input (or pressing the "EMERGENCY ABORT" button from the

access level 2 (see p. 6.3), during the pre-discharge-warning time, the extinguishing signal is

blocked, "EMERGENCY ABORT" indicator lighting (Table 4.2). Transmission of the extinguishing

signal possible after the manual resetting of the ECD activation mode and receiving new

activation signals from Z1&Z2 inputs or «РЗ» input.

The algorithm for «АЗ»input and dependent outputs are shown in fig. 4.6.

Figure 4.6 –«Emergency abort»algorithm («АЗ»input)

4.3.6 «КП»input (Flow control)

If the design of the fixed fire extinguishing system provides for the function of controlling

the release of extinguishing agent, it is necessary to activate the "КП" input. The ECD is

switched to the Release mode after confirming the release of the fire-extinguishing substance

or a signal about its spontaneous release ("Release 2" mode - see point 4.1). Algorithms of the

ECD operation using the flow control function are shown in fig. 4.7, the indication is shown in

Table. 4.2.

Algorithms of the ECD operation with Flow control function:

a) in the ECD Quiescent mode when the "KP" input is activated (for example, spontaneous

release of a fire extinguishing agent occurred) - the ECD switches to the "Release 2"

mode and activates the evacuation alert (sirens) without activating the output to the

fire extinguishing equipment –"П+/П-" (Fig. 4.7 a);

b) upon activation from the inputs "Z1" and "Z2", or "РЗ", the ECD waits for a confirmation

signal about the release of the extinguishing agent at the input "КП", and only after that

the "Release 2" mode is set and the output "ГАС" is activated (Fig. 4.7 b).
