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.

4.3.3 «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.

10
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).
а)
б)
Figure 4.7 –Algorithms with the Flow control function is enabled

11
If the "КП" input is faulty, the ECD works according to the usual algorithm (without
waiting for confirmation about the release of fire extinguishing agent).
4.3.7 «МК» input (Monitoring of status of components)
The «МК»input is used to detect the fault status of individual components of the fixed fire
extinguishing system and transmit it to the "FT" output. The "MK" input status does not affect
other functions or ECD operation algorithm.
The "MK" input can transmit the status of such components as: fire doors, dampers, weight
or pressure sensors of extinguishing equipment, etc. The number of connected outputs of the
components is according to the needs of the consumer, but it is necessary to ensure that the
operating conditions of the MK input are not violated (Table 4.1, Fig. 4.3)
4.3.8 «ТМ» input (Touch Memory)
The "TM" input is used to connect Touch Memory readers (1-wire, iButton), which enable
access to the Level 2 or remote activation/deactivation of the "Manual" mode. One key per
mode and no more than two keys per user can be used (see Table 6.1).
4.3.9 «ДВ» input (door status monitoring)
The «ДВ»input is used to connect opening detectors installed on the entrance door of
the premises. When the input is activated, the ECD switches to the "Manual" mode, the "ДВ"
and "MANUAL MODE" indicators light up (see Table 4.2). Exit from the "Manual" mode is
possible only from the access Level 2 of (see p. 6.3) by pressing the "MANUAL MODE" button
or applying the TM key.
4.3.10 «П+/П-» output (release equipment)
The output is intended for transmitting the launch signal to the extinguishing equipment,
as well as for monitoring the communication line between the ECD and the extinguishing
equipment. The output is activated in the "Release" mode. The output can be in an active state
from 1 to 60 s or until the reset procedure is performed after the extinguishing agent release
time has expired (see Table 6.1). The required activation time of the output should be selected
on the technical characteristics of the extinguishing equipment used.
4.3.11 «SIR» output (evacuation alert)
The output is intended for transmitting a signal to warning devices (sound and light),
which are intended to alert about preparation for the release of a fire-extinguishing agent
("Gas, exit!", "Aerosol, do not enter!", etc.), and about the release of a fire-extinguishing agent.
The output monitors the communication line with the sirens. The connection diagram is
shown in Fig. A.4 of Appendix A. The output has two operation modes that are set
automatically: intermittent and continuous.
Intermittent mode: turns on during the pre-discharge-warning time countdown, the
output is activated for 0.8 s with a period of 1.6 s (Fig. 4.6).
Continuous mode - the output is activated continuously, during the "Release" mode.
If the "SIR" output or the communication line with the sirens is failure, the "Release" mode
cannot be reached.
It is possible to disable the "SIR" output only after completing the "Release" or "Release 2"
mode (see p. 6.3.2).

12
Note - when the "SIR" output is disabled, the "П+/П-" output is automatically
disabled.
When the "П+/П-" output is enabled, the "SIR" output is automatically enabled, if it was
disabled before.
4.3.12 «ГАС» output
This "open collector" type output activates simultaneously with “П+/П-”output.
4.3.13 «ВП» output (Emergency abort)
The "open collector" type output activates when the "AЗ" input is activated or the
"EMERGENCY ABORT" button is pressed from the access level 2 (see item 6.3) and remains
active until manual reset (fig. 4.6).
4.3.14 «AL» output (Alarm)
The "open collector" type output activates when: any of the ECD zones are activated, the
"РЗ" input is activated, the "MANUAL RELEASE" button is pressed from the access level 2, or an
activation signal is received from the FCP.
4.3.15 «ВА» output (Manual mode)
The "open collector" type output activates when the ECD is going to the "Manual" mode.
4.3.16 «FT» output (Fault)
The "open collector" type normally closed output activates when fault of any of ECD
controlled function (circuits) is detected.
4.3.17 Power supply inputs
The ECD has several inputs for connecting an external power supply:
- "U1/U2" (main and backup) - for supplying the ECD and sirens;
- "UП+/UП-" - for supplying the output "П+/П-" to the fire extinguishing equipment.
These inputs can be connected to one common power supply unit or to several different
ones. The power supply unit should meet the requirements of DSTU EN54-4:2003 "Fire alarm
systems. Part 4. Power supply equipment (EN 54-4:1997, IDT). The voltage of the power supply
connected to the ECD and the fire extinguishing equipment must correspond to the values
indicated in Table. 4.1 depending on the programmed settings (table 6.1).
4.3.18 ECD connection to FCP «Tiras PRIME» and «Tiras PRIME A»interfaces
"A", "B" contacts are used to connect the ECD to the FCP "Tiras PRIME" via the RS-485
interface.
The ХР2 slot (Fig. A.1, Appendix A) on the ECD board is used to connect it via AM-Converter
to the address loop of the FCP Tiras PRIME A.
The messages specified in Appendix B are transmitted through the specified interfaces.

5 Installation and preparation for operation
5.1 Installation
5.1.1 The design of the ECD allows it mounting on the wall. At the base of the ECD
enclosure there are 4 mounting holes and holes for cables entry (Fig. 5.1).
Figure 5.1 –The open ECD enclosure appearance

17
When entering cables, minimum gaps shall be provided between the edges of the holes
and the cables isolations. If any of the cable entry holes will not be used, do not break their
falseplates.
5.1.2 The enclosure cover with the control and indication board fixed on it opens from
the upper edge and turns down. To open, press one by one on the spring latches, which are
located in the holes on the side walls of the enclosure, starting from the upper ones (Fig. 5.2).
Figure 5.2 –ECD enclosure opening
If the ECD will be mounted on the wall, it is necessary to ensure the possibility of
convenient access to it.
5.2 Inputs and outputs connection
5.2.1 The ECD inputs and outputs should be connected in accordance with the project of
the fixed fire extinguishing system and the recommendations given in this passport.
If any of the inputs: "Z1", "Z2", "MK", "KП", "ДВ", "РЗ", "АЗ" will not be used, it should be
connected to the terminals "GND" through resistor 6.8 kΩ, 0.5 W.
WARNING! In order to prevent the failure of the ECD, it is necessary to limit the
current in the circuits connected to the "open collector" type outputs ("ГАС", "ВП", "AL",
"FT", "ВА") to the level of 150 mA (see Table 3.1, Fig. A6, A7 of Appendix A).
5.2.2 Connection diagrams of individual components of the fixed fire extinguishing
system to the ECD inputs and outputs are shown in figures A.2 - A.7 (Appendix A).
No more than 32 detectors can be connected to each of the inputs "Z1", "Z2".
WARNING! It is necessary to connect the fire extinguishing equipment ("П+/П-"
inputs) only with protective diodes, as shown in fig. A.5 of Appendix A.
5.2.3 Stranded or solid copper wires with a recommended cross-sectional area 0.22-
0.5 mm2should be connected to the input and output terminals (except those specified
in 5.2.3).

18
5.2.4 The power supply of the sirens and the fire extinguishing equipment should be
connected to the ECD terminals using of the copper wires with a cross-sectional area
corresponding to the current consumption.
The voltage of the power source connected to the ECD and the fire extinguishing
equipment must correspond to the values indicated in Table. 4.1 depending on the
programmed settings (table 6.1).
WARNING! The device and the power supply unit should be placed as close as
possible to the fire extinguishing equipment to ensure the minimum length of the
cables and, accordingly, reduce the voltage drop on the cables.
For example, with a distance from the power supply unit to the fire extinguishing
equipment of 50 m and a load current of 3 A, in a two-wires line with a cross section of
2.0 mm2, the voltage drop will be 2.8 V.
The power supply lines between the power supply unit and the ECD, which are outside
the enclosure and have a length of more than 10 cm, should be protected from mechanical
damage.
5.2.5 To connect to the "A", "B", "GND" terminals of the RS-485 interface, a "twisted pair"
type cable should be used. In conditions of significant industrial electromagnetic interference,
it is recommended to use a shielded cable. The shield should be connected to the grounding
terminals only at one of the two ends of the line (in the ECD it is the "GND" terminal).
5.2.6 The ECD has fire routing output “AL” (normally open) and fault routing output “FT”.
(normally closed) to transmit to the FARC respectively the fire alarm signal and the fault signal.
5.2.7 An example of connecting the ECD to the gas fire extinguishing system is shown in
fig. A.8, Appendix A.
5.3 Preparation for operation
5.3.1 After installing the ECD, the following actions should be carried out:
- in accordance with clause 6.2, reset the ECD to factory settings;
