If the computer is used as net controller then the device has to com-
municate with it through the RS-232/RS-485 converter (such as PI-GR,
S2000-PI or S2000-USB) or S2000/S2000M console manufactured by NVP
BOLID.
If the device has disconnected from the net controller during mes-
sage generation the event report would be stored in the device non-volatile
memory. When the connection has recovered the message is transmitted
to the net controller with the date and time of its origin being noted. The
event buffer storage of the device non-volatile memory is sized to 62
events.
The two device’s power supply inputs are unrelated allowing all de-
vice components uninterruptible power supplying when one line open or
short trouble has occurred or one voltage source has failed. Any input volt-
age supply having dropped to 10 V, the device transits to the “Power
Failed” status. When voltage supply has exceeded 11 V the device returns
to the operating mode (see section 4.3.1). If both main and backup power
supplies have dropped below 9 V the device has shut down.
The typical consumed current values in various operating modes
don’t exceed those shown in Table 1.
Table 1: Consumed current in different modes

then presented value is referred to the maximum from input voltage values.
If device loops are loaded incompletely and the common current

can be considered as linearly increasing together with the detector con-
sumed current increments.
So the device useful current can be calculated in accordance with the
formulas:
The supply voltage being equal to 12 V,
I = 3,33×i + 400 [мА]
The supply voltage being equal to 24 V,
I = 1,67×i + 200 [мА]
where Iis the common device consumed current (without regard to
external notification devices) expressed in мА
iis the consumed current of active detectors included into the
device alarm loops expressed in мА
The common reserve time is calculated by formula
T = 1000 × W/I hours
Wis the accumulator capacity in А⋅ч
Iis the device consumed current in мА
The device in operating mode supplies loop inputs by from 19 to 22 V
DC voltage provided the terminal resistance is equal to 4,7 kОhm ±5% and
the detector consumed current doesn’t exceed 3 mА. This voltage level is
kept even in case of short circuit failure in one of the alarm loops. More then
4 loop short failures together are not allowed. The short closed loop current
is restricted by 26,5 mA.
The ripple voltage effective value does not exceed 20 mV.
If burglary detectors are included into the alarm loop (burglary alarm
loop) the device provides in operating mode:
- the value of loop resistance being equal no more than 1 kOhm with-
out regard to external element;
- the value of leakage resistance between wires or between any wire
and ground being equal no less than 20 kOhm.
If fire detectors are included into the alarm loop (fire alarm loop) the
device provides in operating mode:
- the value of the loop resistance being equal to value no more than
100 Ohm without regard to external element;
- the value of leakage resistance between wires or between any wire
and ground being equal no less than 50 kOhm.
The device’s loops are resistant to electromagnetic effects being
harmonic electromagnetic pickup with 50 Hz frequency and 1 V effective
voltage.

4 DESIGN AND OPERATING PRINCIPLES
The device view along with its overall and mounting dimensions are
demonstrated by Appendix A.
There is “Ready” LED, indicating the device operating modes on the
device cover. On the device base there is the radioelement printed-circuit
board along with external connection terminals and tamper.
The device block scheme diagram is shown in the Appendix B.
The basic device components are:
−power supply inputs
−27 V voltage converter
−5 V voltage converter
−circuit switch
−light indicator
−relays
−loop power dump unit
−RS-485 interface converter
−nonvolatile memory
−tamper
The voltage is delivered from the alarm loop metering circuits to the
circuit switch. Controlling the switch, the processor subsequently connects
in-built analogue digital converter input to the alarm loops. In such a proc-
ess the loop resistance and loop status are estimated.
The 27 V voltage converter shapes stabilized loop supply voltage, the
5 V voltage converter shaping stabilized one for digital subcircuit.

SIGNAL-20P DESIGN AND OPERATING PRINCIPLES
11
The processor controls device operating as whole:
−subsequently requests alarm loops and monitors their statuses
measuring their resistances
−controls the internal light indicators, relay and loop power dump unit
−receives the commands from net controller and transmits mes-
sages to this one via RS-485 interface
In order to accord with the 2-lined RS-485 the interface converter is
used.
The nonvolatile memory is designed to story the event messages
along with the time and date of their origins.
4.1 Alarm loops
The device monitors twenty alarm loops and depending on their
statuses generates the alarm and service messages transmitting them to
the net controller (either ARM Orion or S2000/S2000M console), and con-
trols five in-built relays.
The alarm loop status is defined by its type, its resistance and by its
logical state that is armed or disarmed.
All DC voltage detectors both burglary and fire can be included into
alarm loops, with internal detector resistance in “Fire” mode being:
−no more than 2,7 kOhm for normally opened detectors
−no more than 3,2 kOhm for normally closed detectors

4.1.1.1 Loop Type
The fundamental configuration parameter identifying the loop control
method and types of detectors to be included is represented by “Loop
Type”. The device supports nine alarm loop types.
The type 1 is the fire smoke loop with double actuation recogni-
tion.
The fire smoke (normally opened) detectors are included into the
alarm loop. The alarm loop statuses can be:
“Armed” – the alarm loop is monitored and its resistance is in normal
range.
“Disarmed” - the alarm loop is not monitored.
“Arm delay” – the arming delay has not yet been elapsed.
“Fire prealarm” – the single detector actuation has been fixed.
“Fire alarm” - actuating more than one detector has been fixed, or af-
ter first detector actuation the Intrusion/Fire delay has expired.
“Loop trbl short” – the alarm loop resistance is less than 100 Ohm.
“Loop trbl open” - the alarm loop resistance is more than 6 KOhm.
“Arm Failed” – the alarm loop was broken when arming.
When detector has actuated the device generates the “Fire Signal”
message and de-energizes the alarm loop for a 3 s. If within 55 seconds
after de-energizing the detector connected to this loop repeats actuation

INTRUSION&FIRE ALARM ADDRESSABLE 20-LOOP CONTROL DEVICE
14
this loop enters the “Fire Prealarm” status. If the second actuating has not
occurred within 55 seconds the alarm loop returns to the “Armed” status.
From the “Fire Prealarm” mode the device can transit to the “Fire alarm”
mode if the second detector has been actuated or “Intrusion/Fire Delay”
has expired at this loop. If “Intrusion/Fire Delay” was given as 0 then the
transition from “Fire prealarm” to “Fire alarm” mode would happen instantly.
If “Intrusion/Fire Delay” was given as maximum value 255 then the transi-
tion from “Fire prealarm” to “Fire alarm” would be able only after actuating
of the second detector at the same loop.
The type 1 alarm loop resolving time is determined in accordance
with the requirements of the section 4.1.2.
The coupling between the alarm loop resistances and statuses can
be shown in Table 3.
The diagram of connection the fire smoke (normally opened) detec-
tors to the type 1 alarm loop is contained into the Appendix E.
The type 2 is the fire combined alarm loop.
The fire smoke (normally opened) and heat (normally closed) detec-
tors are included into the alarm loop. The alarm loop statuses can be:
“Armed” – the alarm loop is monitored and the resistance is in normal
range.
“Disarmed” - the alarm loop is not monitored.
“Arm delay” – the arming delay has not yet been elapsed.
“Fire prealarm” – the heat detector actuation or second smoke detec-
tor actuation has been fixed.
“Fire alarm” - after detector actuation the “Intrusion/Fire Delay” has
expired.
“Loop trbl short” – the alarm loop resistance is less than 100 Ohm.
“Loop trbl open” - the alarm loop resistance is more than 16 KOhm.
“Arm Failed” – the alarm loop was broken when arming.
When heat detector has actuated the device enters the “Fire
Prealarm” mode. When smoke detector has actuated the device generates
“Fire Signal” message and repeatedly requests the alarm loop status (see
type 1). If within 55 seconds after de-energizing the detector connected to
this loop repeats actuating the device enter the “Fire Prealarm” mode.
From the “Fire Prealarm” mode the device can transit to the “Fire
alarm” mode if “Intrusion/Fire Delay” has expired. If “Intrusion/Fire Delay”
was given as 0 then the transition from “Fire prealarm” to “Fire alarm” mode
would happen instantly. If “Intrusion/Fire Delay” was given as maximum
value 255 then the transition from “Fire prealarm” to “Fire alarm” would be
impossible.

SIGNAL-20P DESIGN AND OPERATING PRINCIPLES
15
The type 2 alarm loop resolving time is determined in accordance
with the requirements of the section 4.1.2.
The compatibility of loop resistance and the corresponding status can
be shown at the Table 3.
The diagram of connection the fire smoke (normally opened) and
heat (normally closed) detectors to the type 2 alarm loop is contained into
the Appendix E.
The type 3 is the fire heat loop with double actuation recogni-
tion.
The fire heat (normally closed) detectors are included into the alarm
loop. The alarm loop statuses can be:
“Armed” – the alarm loop is monitored and the resistance is in normal
range.
“Disarmed” - the alarm loop is not monitored.
“Arm delay” – the arming delay has not yet been elapsed.
“Fire prealarm” – the one detector actuation has been fixed.
“Fire alarm” - actuating more than one detector has been fixed, or the
Intrusion/Fire delay has expired after single detector actuation.
“Loop trbl short” – the alarm loop resistance is less than 2 KOhm.
“Loop trbl open” - the alarm loop resistance is more than 25 KOhm.
“Arm Failed” – the alarm loop was broken when arming.
When the detector in such alarm loop has actuated the device enters
the “Fire Prealarm” mode. The device enters the “Fire Alarm” mode from
“Fire Prealarm” if the second detector has been activated at this loop or “In-
trusion/Fire Delay” has been expired. If “Intrusion/Fire Delay” was given as
0 then the transition from “Fire prealarm” to “Fire alarm” mode would hap-
pen instantly. If “Intrusion/Fire Delay” was given as maximum value 255
then the transition from “Fire prealarm” to “Fire alarm” would be able only if
the second detector in this loop has actuated.
The type 3 alarm loop resolving time is determined in accordance
with the requirements of the section 4.1.2.
The compatibility of loop resistance and the corresponding status can
be shown at the Table 3.
The diagram of connection the heat (normally closed) detectors to the
type 3 alarm loop is contained into the Appendix E.
The type 4 is the burglary alarm loop.
The alarm loop includes burglary detectors of all types, including nor-
mally closed, normally opened, powerless, supplied via alarm loop or sepa-
rately.
The alarm loop statuses can be:

INTRUSION&FIRE ALARM ADDRESSABLE 20-LOOP CONTROL DEVICE
16
“Armed” – the alarm loop is monitored and its resistance is in normal
range.
“Disarmed” - the alarm loop is not monitored.
“Arm delay” – the arming delay has not yet been elapsed.
“Intrusion alarm” – the detector breaking has been fixed.
“Arm Failed” – the alarm loop was broken when arming.
The intrusion alarm loop is considered as broken if its resistance has
been out of 2…6 KOhm range or skipped more then 10% (refer to “10%
Deviation Blocking” parameter). The breaking of the armed loop leads the
loop to the “Intrusion Alarm” status.
The type 4 alarm loop resolving time is 70 ms or 300 ms depending
on “300 ms Integration” parameter value.
The compatibility of loop resistance and the corresponding status can
be shown at the Table 3.
The diagram of connection burglary detector to the type 4 alarm loop
is contained into the Appendix E.
The type 5 is the burglary alarm loop with tamper check.
The alarm loop includes burglary detector with normally closed con-
tacts and tamper detector.
The alarm loop statuses can be:
“Armed” – the alarm loop is monitored and the resistance is in normal
range.
“Disarmed” - the alarm loop is not monitored.
“Arm Delay” – the arming delay has not yet been elapsed.
“Intrusion Alarm” – the detector breaking has been fixed.
“Arm Failed” – the alarm loop was broken when arming.
“Tamper Alarm” – the loop being disarmed, the tamper has actuated.
“Loop Trbl Short” - the loop being disarmed, its resistance is less then
100 Ohm.
When alarm loop is armed then more than 10% hopping, or the de-
tector actuation (opening of its burglary contact), or tamper actuation
switches the loop to the “Intrusion Alarm” mode. When alarm loop is not
armed (being in statuses “Disarmed”, “Arm delay” or “Arm failed”) tamper
actuation switches the loop to the “Tamper Alarm” status. The loop short
failure is the cause of “Loop Trbl Short” status.
The type 5 alarm loop resolving time is 70 ms or 300 ms depending
on “300 ms Integration” parameter value.
The compatibility of loop resistance and the corresponding status can
be shown at the Table 3.

SIGNAL-20P DESIGN AND OPERATING PRINCIPLES
17
The diagram of connection burglary detector with tamper check to the
type 5 alarm loop is contained into the Appendix E.
The type 6 is the auxiliary alarm loop.
The auxiliary alarm loop is intended to control the status, actuations
and operability of extinguishing equipment and to control the detectors or
other equipment independent from burglary or fire alarming. The detectors
or devices with “dry contact” output (normally opened or closed), or with
“open collector” output are included in alarm loop of this type.
The alarm loop statuses can be:
“Aux Zone Alarm”;
“Aux Zone Restore”.
If the alarm loop resistance has come out of 2…6 kOhm range for
more than 300 ms the loop has entered the “Aux Zone Alarm” status. The
loop resistance having been within 2…6 kOhm range for more than “Arm-
ing Delay” sec, the loop enters the “Aux Zone Restore” status.
The auxiliary alarm loop is impossible to disarm, it is monitored per-
manently. Having received the arming/disarming command the device
generates the current loop status message.
Alarm loop status having been changed, the corresponding mes-
sages are sent to the net controller (S2000/S2000-M console or ARM
Orion). These messages are not storied in nonvolatile device memory. So if
during net controller disconnection several status changes had occurred
then when connection has recovered either only one message would be
sent to the net controller or no messages would be sent if the current
status is equal the last sent one.
Auxiliary alarm loop being associated with a relay, its failure blocks
up the switching of relays assigning to the 1-8 (general purpose), 11
(ASPT), 12 (Siren), 33 (ASPT-1), 34 (ASPT-A) and 35 (ASPT-A1) pro-
grams (see Table 5). This feature can be used, for example, in order to
block the automatically starting of a gas fire extinguishing system if the
door to the protected premises is opened.
The compatibility of loop resistance and the corresponding status can
be shown at the Table 3.
The connection of normally opened or normally closed detectors and
other controlled “dry contact” circuits to the type 6 alarm loop is identical to
the connection of burglary detectors to type 4 loop (see Appendix E).
The type 7 is the entering alarm loop.
All types of burglary detectors including opening or closing, power-
less or power supplied via alarm loop or separately are to be connected to
the type 7 alarm loop.
The alarm loop statuses can be:

INTRUSION&FIRE ALARM ADDRESSABLE 20-LOOP CONTROL DEVICE
18
“Armed” – the alarm loop is monitored and the resistance is in normal
range.
“Disarmed” - the alarm loop is not monitored.
“Arm Delay” – the arming delay has not yet been elapsed.
“Entry Alarm” – the loop breaking has been fixed.
“Intrusion Alarm” – after having entered “Entry Alarm” status the “In-
trusion/Fire Delay” period has expired.
“Arm Failed” – the alarm loop was broken when arming.
The performance and parameters of entering alarm loop are identical
to those of type 4 burglary alarm loop, except that breaking of armed loop
switches it at first to the “Entry Alarm”. If within the “Intrusion/Fire Delay”
period no arming or disarming of the alarm loop has occurred the loop
would enter to the “Intrusion Alarm” status.
While the alarm loop is in the “Entry Alarm” status the relay switching
by means of executive general purpose programs 1 – 8 or SIREN program
12 does not perform.
This type alarm loop resolving time is 70 ms or 300 ms depending on
“300 ms Integration” parameter value.
The compatibility of loop resistance and the corresponding status can
be shown at the Table 3.
The diagram of connection burglary detectors to the type 7 alarm
loop is identical to type 4 loop connection diagram and is contained into the
Appendix E.
The type 11 is the alarming loop.
The alarming loop includes normally opened and normally closed
alarm devices (call points, footboards and so on).
The alarm loop statuses can be:
“Armed” – the alarm loop is monitored and its resistance is in normal
range.
“Disarmed” - the alarm loop is not monitored.
“Arm Delay” – the arming delay has not yet been elapsed.
“Silent Alarm” – attack, the alarm loop breaking has been detected.
“Arm Failed” – the alarm loop was broken when arming.
The operating and parameter settings of the alarming loop are similar
to those of type 4 loop except that breaking of the armed alarming loop
leads it to the “Silent alarm” status.
This status impacts only the relay controlled by means of 10 program
(Alarm output 1) or 16 program (Alarm output 2) with relay being opened.
The external audible and visible alarms controlled by LAMP (9) and SIREN
(12) programs don’t change their statuses.

This type alarm loop resolving time is 70 ms or 300 ms depending on
“300 ms Integration” parameter value.
The compatibility of loop resistance and the corresponding status can
be shown at the Table 3.
The diagram of connection call points and other alarms to the type 11
alarm loop is similar to the type 4 loop connecting diagram and is con-
tained into the Appendix E.
The type 12 is the programmable auxiliary alarm loop.
This alarm loop type can be used to control the variety of equipment,
among them the devices not dealing with burglary or fire alarming. The de-
tectors or devices with “dry contact” output (normally opened or closed), or
with “open collector” output are included in alarm loop of this type.
The programmable auxiliary alarm loop can have up to 5 various
statuses that are defined by loop resistance. One can program both
statuses and the corresponding threshold resistance values. In so manner
the equipment having several statuses and several associated output con-
tact groups can be monitored via one alarm loop by means of including the
contact groups into alarm loop complemented with additional or shunt re-
sistances. Moreover one can control short or open failures of this loop.
Audible and light alarming and the influence of this loop on the relay
are defined by the statuses this alarms can have.
Status changing of the programmable auxiliary alarm loop depends
only on the alarm loop resistance changing and is not defined by any loop
parameters or arming/disarming commands.
The resolving time in case of status changing is equal to 300 ms. If
alarm loop is entering “Armed”, “Disarmed”, “Aux Zone Restore” or one of
recovering statuses then the transition has been considered as completed
after "Arming Delay" seconds.
The programmable auxiliary alarm loop is impossible to disarm, it is
monitored permanently. Having received the programmable auxiliary loop
arming/disarming command the device generates the current loop status
message.
Programmable auxiliary alarm loop status having been changed, the
corresponding messages are sent to the net controller (S2000/S2000-M
console or ARM Orion). These messages are not storied in nonvolatile de-
vice memory. So if during net controller disconnection several status
changes have occurred then when connection is recovered either only one
message would be sent to the net controller or no messages would be sent
if the current status is equal the last sent one.

4.1.1.2 Arming Delay
The parameter "Arming Delay" defines the number of seconds you
want the device to wait before arming the alarm loop after having received
the corresponding command. Nonzero "Arming Delay" is normally used for
entering alarm loop when after entering arming command it should be pos-
sible for some time to break this loop without alarm going off. If before loop
arming it is necessary to switch relay on (the executive program 17 “Turn
on for a given time before arming”) then the “Arming delay” loop parameter
has to be set to a nonzero value. Otherwise the relay will not switch on be-
cause of the switching time for this program must not exceed the “Arming
delay” loop parameter.
4.1.1.3 Intrusion/Fire Delay
For entering alarm loop (type 7) the “Intrusion/Fire Delay” parameter
means the transition delay from “Entry Alarm” to “Intrusion Alarm” status
and is considered as “entering duration”. “Intrusion/Fire Delay” is given to
make it possible to disarm alarm loop after entering loop breaking.
For entering alarm loop (types 1, 2, 3) the “Intrusion/Fire Delay” pa-
rameter means the period of loop transition from “Fire prealarm” to “Fire
alarm” status. Alarm loops with double actuation recognition (types 1 and
3) can transit to the “Fire alarm” status when second fire detector in this
loop has actuated. If “Intrusion/Fire Delay” is set to 255 s it means unlim-
ited delay when the device does not enter to the “Fire Prealarm” status due
to the time conditions. In this case type 1 or 3 alarm loop can enter the
“Fire Alarm” status only together with second loop detector actuation, but
type 2 alarm loop can not enter the “Fire Alarm” status under any condi-
tions.
4.1.1.4 Loop Analysis Delay after Reset
If the resistance of arming loop is less than lower threshold, for ex-
ample, as a result of smoke fire detector having actuated, then the device
automatically reset alarm loop shutting off its power voltage for 3 s. The
“Loop Analysis Delay after Reset” parameter for any type loop is the du-
ration of pause after power shutting off before loop status analysis. This
delay allows including the detectors with long warm-up time (or long read-
ing time) in the alarm loop. If the loop power supplied detectors enters to
the operating mode (and requires higher current consumption) during long
time after loop resetting then it is necessary to set the “Loop Analysis De-
lay After Reset” parameter to the value just over maximum warm-up time of
loop included detectors.
The minimum operating delay amounts to 1 s. The value of “Loop
Analysis Delay After Reset” parameter can vary from 1 up to 63 s.
