1.4.2 Inputs
1.4.2.1 The control panel provides monitoring of 20 inputs for connecting fire (intrusion,
alarm or auxiliary) input circuits with normally open/ closed internal contacts.
Monitoring is based on the measuring of the input circuit resistance.
1.4.2.2 Device inputs can accommodate any types of intrusion and fire detectors designed
to operate at constant voltage. In this case, the internal resistance of the detector in the
alarm mode (‘triggering’) should be:
- no more than 2.7 kΩfor normally open detectors (closed state);
- not less than 3.2 kΩfor normally closed detectors (open state).
1.4.2.3 In the quiescent mode, the panel provides inputs with a constant voltage from 19 to 24 V
with an end-of-line resistor of 4.7 kΩ ± 5% and a detectors current consumption from 0 mA to 3 mA.
1.4.2.4 The effective value of the ripple voltage in the circuit is no more than 20 mV.
1.4.2.5 If one of the inputs is short-circuited, the device provides voltage at the other inputs as
described 1.4.2.3. Long-term closure of more than 3 input circuits at the same time is not allowed.
1.4.2.6 The panel provides limiting the short-circuit current of the input at the level of no more
than 26.5 mA.
1.4.2.7 The panel disconnects the input-circuit voltage to return automatic current-consuming
detectors to the quiescent mode during arming (while resetting alarms).
The duration of the power disconnection is 3.0 s.
The panel power off each input individually.
1.4.2.8 Parameters of communication lines ensuring normal operation of fire input circuits
connected to the control panel inputs are as follows:
- wire resistance without taking into account the terminal resistor is no more than 100 Ω;
- insulation resistance between the input wires is not less than 50 kΩ;
- insulation resistance between input wires and wires of other inputs is not less than 50
kΩ;
- insulation resistance between each wire and ‘earth’is not less than 50 kΩ.
1.4.2.9 Parameters of communication lines ensuring normal operation of intrusion input circuits
connected to the panel inputs are as follows:
- wire resistance without taking into account the terminal resistor - no more than 1 kΩ;
- insulation resistance between input wires not less than 20 kΩ;
- insulation resistance between input wires and wires of other inputs is not less than 20
kΩ;
- insulation resistance between each wire and ‘earth’is not less than 20 kΩ.
1.4.2.10 The logical state of the input is defined by:
–its type;

11
–logic configuration parameters;
–electrical resistance;
–mode (armed (enabled) or disarmed (disabled), etc.).
1.4.2.11 In accordance with the logical state of the inputs, the panel:
–displays their status on indicators ‘1’... ‘20’;
–controls the built-in buzzer when the inputs go into alarm states or when a fault occurs;
–generates discrete signals FIRE, ‘Fault’, ‘Start’, ‘Alarm’;
–controls sound and light alarm devices;

1.4.2.13.0. The Input Type is a main configuration parameter that determines an input
monitoring method and the class of connected detectors. The panel supports 12 input
types.
1.4.2.13.1. Type 1: Smoke Fire Two-Threshold
The input supports smoke fire two-threshold (normally-open) detectors
The input-circuit resistance corresponding to different physical states is shown in Table 1.4.2.3.
The boundary between the physical states Activation of 1 smoke detector and Activation of 2 or
more smoke detectors is dynamic and automatically calculated by the Panel depending on the total current
consumed by the detectors in the Armed status.
Possible logical states of the input:
- ARMED (ARMED, ENABLED) - the input is monitored, the circuit resistance is normal;
- DISARMED (‘DISARMED’) - the input is not monitored;
- DISABLED - the input is not monitored, the monitoring is disabled by the network controller;
- ARMING DELAY - the arming is still in progress;
- PRE-ALARM –triggering of one detector (when the Fire Input Requery Inhibit parameter is
enabled);
–FIRE - the input switches to this state of the following occurs:
the triggering of one detector is confirmed (after a requery);

14
the triggering of two detectors occurs (the Fire Input Requery Inhibit parameter
enabled) in one input circuit in a time not exceeding 120 s;
the second transition to the PRE-ALRM state of different inputs of the same zone is
registered in a time not exceeding 120 s provided the input that gone to the PRE-ALARM
state first does not change its state
–FIRE2 - the input goes to this state if the following occurs:
the triggering of two detectors (after a requery) in one input circuit is confirmed within a
time not exceeding 120 s;
the second transition to the FIRE state of different inputs of the same zone occurs in a time
not exceeding 120 s and the input that gone into the FIRE state first does not change its
state.
- SHORT CIRCUIT - input circuit resistance is less than 100 Ω;
- OPEN CIRCUIT - input resistance is more than 6 kΩ;
- ARMING FAILED –the input is not normal at the moment of arming.
Algorithm of Two-Threshold Fire Smoke Input
Input disablement (transition to the DISABLED status) can be done only manually using the
DISABLE command of the network controller (the S2000-M panel ver.4.13 (3.13) or newer).
When monitoring is enabled, the input goes from Disabled to one of the following states:
–ARMING DELAY
–ARMED
–ARMING FAILED
The input monitoring can be enabled by the following way:
manually by ENABLE command of the network controller (S2000M panel v.4.13 (3.13)
and higher);
manually by ARM or ENABLE command of the network controller (S2000M panel v.4.12
(3.12) and lower)
manually using the Signal-20M controls when operated in combination with the S2000M
control panel v.4.12 (3.12) and lower;
manually using the Signal-20M controls in standalone operation.
The input enablement can be done only manually using the Signal-20M own controls or by a
command of the network controller.
If during attempt to arm the input, the resistance is less than normal, for example, a smoke detector
triggering occurred in the input circuit, the control panel automatically resets input (turns off the power of
this input for 3 seconds). This allows automatic current-consuming detectors to be returned to the
quiescent mode.
The device starts evaluating the input resistance after a delay defined by the Delay Analysis after
Reset parameter. If after the power reset, the resistance of the input is not within the normal range, the
input goes into the ARMING FAILED status.
Being in ARMING FAILED state, the input can go to the following states:

15
- DISARMED –manually using the panel controls or by the command of the network controller;
- ARMED:
manually using the panel controls or by the command of the network controller;
automatically when the configuration parameter Reaming If Arming Failed is enabled, if
the input resistance is in the normal range.
In the ARMED state, the control panel monitors an input circuit for short-circuit and open-circuit
faults, one detector triggering, two and more detectors triggering.
In case of input short circuit, the input switches from the ARMED state to the SHORT CIRCUIT
(OPEN-CIRCUIT) state, respectively. When the input is restored (if the resistance goes into the normal
range), the input automatically switches to the ARMED state.
Algorithm of input operation in the ARMED state with a disabled Fire Input Requery
Inhibit parameter:
Upon the detector triggering, the control panel generates the Detector Signal event message and
resets the input state: it powers off the input for 3 seconds. After a delay defined by the Analysis Delay
after Reset parameter, the Panel starts evaluating the input-circuit resistance. If the detector is triggered
again within 55 seconds, the input goes into the FIRE state, and if two or more detectors are triggered in
the input circuit during this time, it goes to the FIRE2 state. If no detector triggering is recurred within 55
seconds, the input remains in the ARMED state.
When in the FIRE state, the input is still monitored during next 120 seconds till the triggering of a
second detector on this input circuit (triggering of a second detector –requery- retriggering of two
detectors), the input goes to the FIRE2 status. If no second detector is triggered or its triggering is not
confirmed, or it quiescent 120 seconds later after the FIRE status, the input stays in the FIRE status.
When switching to the FIRE state, the triggering of detectors on other inputs are also taken into
account, provided that they belong to the same zone. If upon confirmation of the triggering of the first or
second detector of this input, the other input was already in the FIRE state and the detector on it was
triggered no more than 120 seconds ago, this input goes to the FIRE2 state. Thus, the transition to the
FIRE2 state occur if a confirmed triggering of two fire detectors of the same input or different inputs of
the same zone occurs within two minutes.
Algorithm of input operation in the ARMED state when the Fire Input Requery Inhibit
parameter enabled
Upon detector triggering, the input goes to the PRE-ALARM state.
In the PRE-ALARM state, the control of the input continues, and if the triggering of the second
detector of this input is registered within the next 120 seconds, the input goes to the FIRE state. If the
second detector does not trigger, or it does occur but 120 seconds later after switching to the PRE-
ALARM, the input will remain in the PRE-ALARM state.
When switching to the PRE-ALARM state, the triggering of detectors on other inputs are also
taken into account, provided that they belong to the same zone.

16
When switching to the PRE-ALARM state, the triggering of detectors on other inputs are also
taken into account provided that they belong to the same zone. If upon triggering of a first or second
detector of this input, the other input is already in the PRE-ALARM state and the detector on it was
triggered no more than 120 seconds ago, this input goes to the FIRE state. Thus, the transition to the
FIRE state takes place if triggering of two fire detectors is registered without requery within two minutes
in the same input or different inputs belonging to the same zone.
When switching to the FIRE state, the triggering of detectors on other inputs are also taken into
account, provided that they belong to the same zone. When going to the Fire status, the other input was
already in the FIRE state and the detector on it was triggered no more than 120 seconds ago, this input
goes to the FIRE2 state. Thus, the transition to the FIRE2 state is initiated if different inputs belonging to
the same zone go to the FIRE state twice within two minutes.
When in the PRE-ALRM, FIRE, and FIRE2 states, the input is not monitored for short-circuit
and open-circuit faults.
When in the PRE-ALRM, FIRE, or FIRE2 states, the input can go to the DISARMED,
ARMED (ARMING FAILED if input is or normal) only through manual and network-controller
commands.
Integration Time (Debounce Time) for Input of Type 1 is defined as described in 1.4.2.29, except
for: - Integration time of transition from the ARMINNG FAILED state to the ARMED state is 3
seconds;
- Integration time of transition from the SHORT/OPEN CIRCUIT state to the ARMED state is 1
second.
The connection of fire smoke (normally open) and detectors on the Input of Type 1 is provided in
2.2.4.3.
1.4.2.13.2. Type 2: One-Threshold Fire Combined
The input supports fire smoke (normally open) and heat (normally closed) detectors.
The input resistance corresponding to different physical states is provided in Table 1.4.2.3.
Possible logical states of the input:
–ARMED (ARMED, ENABLED) - the input is monitored, the circuit resistance is normal;
–DISARMED (DISARMED) - the input is not monitored;
–DISABLED - the input is not monitored; the monitoring is disabled by the network controller;
–ARMING DELAY - the arming delay is still in progress;
–PRE-ALARM - the input goes to this state if the following occurs:
Triggering of one detector (when the Fire Input Requery Inhibit parameter is enabled)
Triggering of heat fire detector
–FIRE - the input switches to this state in case of:
the triggering by one heat detector was confirmed (after a requery);
the second transition to the PRE-ALRM state of different inputs of the same zone was
registered in a time not exceeding 120 s. In this case, the input that has gone to the PRE-

–FIRE2 - the input goes to this state if the following occurs:
the second transition to the FIRE state of different inputs of the same zone was occurred in
a time not exceeding 120 seconds provided that the input gone to the FIRE state first does
not change its state.
–SHORT CIRCUIT - input circuit resistance is less than 100 Ω;
–OPEN CIRCUIT –the input resistance is more than 6 kΩ;
–ARMING FAILED –the input was not normal at the moment of arming.
Algorithm of One-Threshold Fire Combined Input
Input disablement (transition to the DISABLED status) can be done manually only using the
DISABLE command of the network controller (the S2000-M panel ver.4.13 (3.13) or newer).
When enabled, the input goes from Disabled to one of the following states:
–ARMING DELAY
–ARMED
–ARMING FAILED
The input monitoring can be enabled by the following way:
manually by ENABLE command of the network controller (S2000M panel v.4.13 (3.13)
and higher);
manually by ARM or ENABLE command of the network controller (S2000M panel v.4.12
(3.12) and lower)
manually using the Signal-20M controls when operated in combination with the S2000M
control panel v.4.12 (3.12) and lower;
manually using the Signal-20M controls, in standalone operation.
The input enablement can be done manually only using the Signal-20M own controls or by a
command of the network controller.
If during an arming attempt, the input resistance is less than normal, for example, a smoke detector
triggering occurred in the input circuit, the control panel automatically resets input (turns off the power of
this input for 3 seconds). This allows automatic current-consuming detectors to be returned to the
quiescent mode.
The device starts evaluating the input resistance after a delay equal to the value of the Delay
Analysis after Reset parameter. If after the power reset, the resistance of the loop is not within the
normal range, the input goes into the ARMING FAILED
If input resistance is higher than normal range at the arming attempt, the input immediately goes to
the ARMING FAILED status.
Being in ARMING FAILED state, the input can go to the following states:
–- DISARMED - manually, using the device controls or by the command of the network controller;
–- ARMED:
manually using the device controls or by the command of the network controller;
automatically when the configuration parameter Reaming If Arming Failed is enabled, if
the input resistance is in the normal range.

18
In the ARMED state, the control panel monitors input circuit for short-circuit and open-circuit
faults, triggering of heat detector and triggering of smoke detector.
In case of input short/open circuit faults, the input goes to the SHORT CIRCUIT (OPEN-
CIRCUIT) state, respectively. When the input is restored (if the resistance returns to the normal range),
the input automatically goes to the ARMED state.
The triggering of heat detector switches the panel to the PRE-ALARM state
When switching to the PRE-ALARM state, the triggering of detectors on other inputs are also
taken into account provided that they belong to the same zone. If upon triggering of a heat detector of this
input, the other input is already in the PRE-ALARM state and the detector on it was triggered 120
seconds ago or earlier, this input goes to the FIRE state. Thus, the transition to the FIRE state occurs if
triggering of two fire heat detectors is occurred within two minutes on different inputs belonging to the
same zone.
When switching to the FIRE state, the triggering of detectors on other inputs are also taken into
account, provided that they belong to the same zone. When going to the Fire status, the other input was
already in the FIRE state and the detector on it was triggered no more than 120 seconds ago, this input
goes to the FIRE2 state. Thus, the transition to the FIRE2 state is initiated if different inputs belonging to
the same zone go the FIRE state second time within two minutes.
When in the PRE-ALRM, FIRE, and FIRE2 states initiated by a heat detector, the input is not
monitored for short-circuit and open-circuit faults. The monitoring for smoke detector triggering is
possible, if the Fire Input Requery Inhibit parameter is not enabled (only if requering is available).
When in the PRE-ALRM, FIRE, or FIRE2 states, the input can go only to the DISARMED,
ARMED (ARMING FAILED if input is or normal) through the manual and network controller
commands.
The monitoring algorithm of smoke detector triggering in ARMED, PRE-ALARM and
FIRE states if Fire Input Requery Inhibit is disabled:
Upon the smoke detector triggering, the control panel generates the Detector Signal event message and
requery the input state: it powers off the input for 3 seconds. After a delay as set in the Analysis Delay
after Reset parameter, the Panel starts evaluating the input-circuit resistance. If the detector triggers again
within 55 seconds, the input goes into the FIRE state. If no detector triggering is recurred within 55
seconds, the input remains in the current state (ARMED, PRE-ALARM, FIRE).
When switching to the FIRE state, the triggering of detectors on other inputs are also taken into
account, provided that they belong to the same zone. When going to the Fire status, the other input was
already in the FIRE state and the detector triggering was no more than 120 seconds ago, this input goes to
the FIRE2 state. Thus, the transition to the FIRE2 state is initiated if different inputs belonging to the
same zone go the FIRE state second time within two minutes.
The monitoring algorithm of smoke detector triggering in ARMED, PRE-ALARM and
FIRE states if Fire Input Requery Inhibit is enabled:

19
On the detector triggering, the input goes to the PRE-ALARM state.
When switching to the PRE-ALARM state, the triggering of detectors on other inputs are also
taken into account provided that they belong to the same zone. If upon smoke detector triggering on this
input, the other input is already in the PRE-ALARM state and the detector on it was triggered no more
than 120 seconds ago, this input goes to the FIRE state. Thus, the transition to the FIRE state occurs two
different inputs of the same zone go to pre-alarm states within two minutes
When switching to the FIRE state, the triggering of detectors on other inputs are also taken into
account, provided that they belong to the same zone. When going to FIRE status, the other input was
already in the FIRE state and the detector triggering was no more than 120 seconds ago, this input goes to
the FIRE2 state. Thus, the transition to the FIRE2 state is initiated if different inputs belonging to the
same zone go the FIRE state second time within two minutes.
The input is not monitored for short-circuit and open-circuit faults in the PRE-ALRM, FIRE, and
FIRE2 states.
When in the PRE-ALRM, FIRE, or FIRE2 states, the input can go only to the DISARMED,
ARMED (ARMING FAILED if input is not normal) through the manual and network-controller
commands.
Debounce Time (Integration Time) for Input of Type 2 is defined as described in 1.4.2.29, except
for: - Debounce Time of switching from the ARMINNG FAILED state to the ARMED state is 3
seconds;
- Debounce Time of switching from the SHORT CIRCUIT (OPEN-CIRCUIT) state to the
ARMED state is 1 second.
The connection of fire smoke (normally open) and fire heat detectors on the Input of Type 2 is
provided in 2.2.4.3.
1.4.2.13.3. Type 3: Heat Fire (Two-Threshold)
The input supports heat fire (normally closed) detectors. The input circuit resistance corresponding
to different physical states is shown in Table 1.4.2.3.
Possible logical states of the input:
–ARMED (ARMED, ENABLED) - the input is monitored, the circuit resistance is normal;
–DISARMED (DISARMED) - the input is not monitored;
–DISABLED - the input is not monitored; the monitoring is disabled by the network controller;
–ARMING DELAY - the arming delay is still in progress;
–PRE-ALARM - one detector triggered;
–FIRE - the input switches to this state in the following situations:
the triggering of two detectors of the same input occurs for the time period not exceeding
120 seconds;
the second transition to the PRE-ALRM state of different inputs of the same zone is
registered during the time period not exceeding 120 seconds provided the input went to the
PRE-ALARM state first does not change its state
–FIRE2 - the input goes to this state if the following occurs:

20
the second transition to the FIRE state of different inputs of the same zone was occurred in
a time not exceeding 120 second. In this case, the input that has passed into the FIRE state
first does not change its state.
–SHORT CIRCUIT - input circuit resistance is less than 100 Ω;
–OPEN CIRCUIT - input resistance is more than 6 kΩ;
–ARMING FAILED –the input is not normal at the moment of arming.
Algorithm of Two-Threshold Fire Heat Input
Input disablement (transition to the DISABLED status) can be done only manually using the
DISABLE command of the network controller (the S2000-M panel ver.4.13 (3.13) or newer ).
When monitoring is enabled, the input goes from Disabled to one if the following states:
–ARMING DELAY
–ARMED
–ARMING FAILED
The input monitoring can be enabled by the following way:
manually by the ENABLE command of the network controller (S2000M panel v.4.13
(3.13) and higher)
manually by the ARM or ENABLE command of the network controller (S2000M panel
v.4.12 (3.12) and lower)
manually using the Signal-20M controls when operated in combination with the S2000M
control panel v.4.12 (3.12) and lower
manually using the Signal-20M controls, in standalone operation
The input enablement can be done manually only using the Signal-20M own controls or by the
command of the network controller.
If during attempt to arm the input, the resistance is beyond the normal range, the input
immediately goes to the Arming Failed state.
Being in ARMING FAILED state, the input can go to the following states:
- DISARMED - manually, using the device controls or by the command of the network controller;
- ARMED:
manually using the device controls or by the command of the network controller;
automatically when the configuration parameter Reaming If Arming Failed is enabled, if
the input resistance is in the normal range.
In the ARMED state, the control panel monitors input circuit for short-circuit and open-circuit
faults, triggering of one detector, triggering of two and more detectors.
On the detector triggering, the input goes to the PRE-ALARM state.

21
In the PRE-ALARM state, the control of the input continues, and if the triggering of the second
detector of this input is registered within the next 120 seconds, the input goes to the FIRE state. If the
second detector does not trigger, or it does occur but 120 seconds later after switching to the PRE-
ALARM, the input will remain in the PRE-ALARM state.
When during switching to the PRE-ALARM state, the triggering of detectors on other inputs are
also taken into account provided that they belong to the same zone. If upon triggering of a heat detector
of this input, the other input is already in the PRE-ALARM state and the detector of this input was
triggered no more than 120 seconds ago, this input goes to the FIRE state. Thus, the transition to the
FIRE state occurs if different inputs of the same zone goes to the PRE-ALARM state during two
minutes.
When switching to the FIRE state, the triggering of detectors on other inputs are also taken into
account, provided that they belong to the same zone. When going to the FIRE status, the other input was
already in the FIRE state and the detector on it was triggered no more than 120 seconds ago, this input
goes to the FIRE2 state. Thus, the transition to the FIRE2 state is initiated if different inputs belonging to
the same zone go FIRE state second time within two minutes.
When in the PRE-ALRM, FIRE, and FIRE2 states, the input is not monitored for short-circuit
and open-circuit faults.
When in the PRE-ALRM, FIRE, or FIRE2 states, the input can go only to the DISARMED,
ARMED (ARMING FAILED if input is or normal) only through manual and network-controller
commands.
Integration Time (Debounce Time) for Input of Type 3 is defined as described in 1.4.2.29, except
for: - Integration time of transition from the ARMINNG FAILED state to the ARMED state is 3
seconds;
- Integration time of transition from the SHORT/OPEN CIRCUIT state to the ARMED state is 1
second.
The connection of fire heat (normally closed) and detectors on the Input of Type 3 is provided in
2.2.4.3.
