Notes.
1 When choosing the values of resistances Rt and Rl, you should take into account the
total resistance of the line when the relay is triggered, this value should not be equal to Rd -
the resistance of the indeterminate state of the line.
2 Switching the device to the activation warning mode is possible only from the standby
mode, in case of fault (short circuit or open circuit), restoring of the device is possible when
returning to the standby mode.
4.3.3 Alert output connection ("OUT1", "OUT2")
The device contains 2 alert connection outputs. Connection of sirens is shown in
fig. 7. When powering the sirens from the device's own output - it is necessary to install
a jumper between the input U12 and output +24V. If the current consumption of the
detectors exceeds the load capacity of the device output +24V, it is necessary to use an
auxiliary power supply. At the end of the warning line, a terminal resistor of 10 kО, 0.5 W
is installed.

The device contains 2 power outputs of external devices, with a voltage of 24 V and
a maximum load current of 400 mA (for each output). Each output has a self-resetting
fuse with a maximum load current of 500 mA. The outputs on the main board are
marked "+ 24V".
To restore the normal state of the output fuse "+ 24V" after its operation,
it is necessary to remove the load from the output for a few seconds.

4.3.5 Main power connection (220V)
The main power is connected via the connector on the PSU of the device. Insert the
cable (Fig. 8) into the terminal socket of the connector and connect it to the plug of the
device. After connection the 220V main connectors, the wire should be fixed with a tie,
see fig. 9. For main power connection it is recommended to use a cable with a cross
section of conductors not less than 0.75 mm

4.3.6 Backup power connection (battery)
As a backup power supply of the device use one sealed lead-acid battery with a
voltage of 12V, capacity 7 A∙h or 9 A∙h. The battery is connected to the terminals "+" (red)
and "-" (black). The device monitors the internal resistance and voltage of the battery -
at a voltage less than 11.5V generates a message: "Battery fault - low voltage", and
disconnects the battery when the voltage drops to 10.5 V to prevent damage to the
battery. Current consumption from the battery after disconnection the device is absent.
The charger contains protection against incorrect battery connection.
The charger performs 3 stages of battery charging:
• charging with current (without voltage limitation, taking into account the
temperature), up to about 80% of capacity;

12
• DC voltage charging (2V less than the value of charge voltage 1 in the first stage,
taking into account the temperature);
• relaxation - disconnection of the charger, the process of self-discharge (storage)
of the battery. In this mode, the batteries are ready to provide backup power to the
device. If the 220V network fails, the transition to the battery is automatic.
After reaching the self-discharge threshold, the charging cycle is repeated. Battery
voltage regulation temperature range from 0 °C to 50 °C.
To start the device from the battery (without 220V network) it is necessary to connect
the battery and press the "BAT START" button (Fig. 3), hold it until the LED indication HL4
(POW). An example of calculation the capacity of the backup power supply is given in
Appendix A.
4.3.7 M-OUT2R and M-LOOP modules installation
The M-OUT2R and M-LOOP modules are mounted on top of the device board in the
appropriate connectors (Fig. 3, Item 4). It is possible to install two identical modules on
the device board.
To install the module, you need to install the plastic holders on the main board of
the device (holders included in the set M-OUT2R and M-LOOP) and install the module on
the main board of the device by connecting the module connector to the device
connector 4).
When the M-OUT2R module is installed, two relay outputs (dry contact type) appear.
When installing M-LOOP modules, additional address interfaces appear.
The modules are set in accordance with the FCP operation manual.
Up to 250 address components can be connected to AM-MULTI+,
regardless of the number of M-LOOP modules installed.
An example of the M-LOOP module installation and its connection terminals is
shown in Fig. 15.

Calculation of battery capacity
A.1 Battery capacity is calculated in order to ensure the operation of the device,
addressable components, connected to it, and other devices of the AFAS in the absence of a
primary power source. According to DSTU-N CEN/TS 54-14:2009 AFAS should work only from
the battery during:
- provided that there is a connection with the FCP "Tiras PRIME A", but when the term
of fault detection exceeds 24 hours –not less than 30 hours in the standby mode and
additionally not less than 30 minutes in the fire alarm mode;
- if the site has spare parts, repair personnel and a backup power generator - not less
than 4 hours in standby mode and additionally not less than 30 minutes in fire alarm mode.
A.2 An example of calculation battery capacity is given below. The number of
components is set separately for each device. Necessary actions:
a) make a list indicating the types of components and the number of components of
each type that are connected to the device according to the project (Table A.1);
b) according to the operation documents to determine the current consumption of
each of the types of components in the standby mode and fire alarm mode;

Is- current consumption of the component in the "standby" mode;
If- current consumption of the component in the "Fire" mode.
c) calculate the total current consumption of components of each type, and then the
total current consumption in the standby mode and in the fire alarm mode:
- current consumption of components in the standby mode:
Is= Is(AM-Multi+) + Is(M-LOOP) + Is(SMK100) + Is(SMK110) + Is(MNL110);
Is= 30x1 + 18x2 + 0.09x200 + 0.13x25 + 0.12x8 = 0.069 A.
- current consumption of components in the mode of fire alarm:
If= If(AM-Multi+) + If(M-LOOP) + If(SMK100) + If(SMK110) + If(MNL110) + If(siren OSZ)
+ If (Siren ОС);
If= 30x1 + 18x2 + 0.09x200 + 0.13x25 + 0.12x8 + 70x5 + 35x8 = 0.725 A.

15
d) calculate the required capacity of all batteries for the standby mode by multiplying
the received total current in the standby mode by the number of hours in the standby mode,
then calculate the required capacity of all batteries for the fire alarm mode by multiplying
the received total current in the fire mode by hours in the alarm mode:
- in the device uses one 12 V battery with a capacity of 7 A∙h or 9 A∙h. The calculations
use 24 V components, so the current consumption from the battery of 12 V components
should be multiplied by 2:
Is= 0.069x2 = 0.138 A;
If= 0.725x2 = 1.55 A.
- provided that there is a connection with the FCP "Tiras PRIME A", but when the term
of elimination of power failure is not more than 24 hours:
Cbattery= (0.138 x30, + 1.55 x 0.5) x1.25 = 6.08 A∙h.
A stock of 25% is taken into account. In this case, a battery with a capacity of 7 A * h is
enough.
A.3 When calculating the required capacity of the battery for the device, it should be
borne in mind that the device is part of the AFAS, so the service life of the device from the
battery should be not less than that set for the AFAS according to project requirements. If
the required calculated battery capacity is greater than the capacity of the battery installed
in the device enclosure, it is necessary to additionally use an external PSU(PS2415, for
example).
