2.3. Connection of Signaling Devices
The monitored outputs SND, at activation, provide 24VDC@0,5A to the load connected between
them and GND*.
The monitored outputs FAULT, EXT and FIRE, provide 24VDC@0,3A to the load connected
between them and GND*.
It is necessary to connect in parallel to the last device in the loop a 10k terminate resistor,
so to ensure that the panel is able to detect any break or short circuit in the loop
– see Figures 10
and 11!

2.3.1 Connecting of Sounders
To every monitored output
SND
could be connected several sounders - Figure 10. The maximum number of sounders
that could be connected in the circuit depends on their total current consumption, which must not exceed 0,5A.
Before connecting the last sounder in the circuit
, parallel to it must be added resistor 10k
.

2.3.2 Connecting of Signaling Devices
To every monitored output
FAULT, EXT and FIRE
could be connected signaling and other control devices
– Figure 11.
The maximal consumption of the devices should not exceed 0.3
А.
Before connecting the last device in the circuit
, parallel to it must be added resistor 10k
.

2.3.3 Connecting to the Specialized Inputs
The specialized inputs of MAGPRO16 fire alarm panel are designed for operation with an extinguishing control panel.
The example connection diagrams are presented on Figures 12
