MAGPRO16 Addressable Fire Alarm Panel – Installation and Programming Manual

2.3.4 Loop Controller
The MAGPRO16 fire alarm panel supports operation with MAGPRO16-L250 loop controller via communication protocol
MAGPRO.
The Loop Controller realizes the connection between the I/O Module and devices connected to the communication
line. The Loop Expander has two basic functions:
Gathers data from the devices in the communication line and transfers it to the main microcontroller;
Receives commands from the main microcontroller and transfers them to the devices connected in the
communication line.
Up to 250 MAGPRO devices can be connected to MAGPRO16-L250 loop controller.
The general connection
diagram of devices to the loop controller is shown on Figure 13.
The maximum current consumption of the devices in the communication line is Imax = 500mA. If the consumption
exceeds this value an over-load protection would be turned on.

In the configuration of addressable fire alarm panel MAGPRO16 could be mounted a second loop controller as a
separate module
– see Figure 14.
ATTENTION! Do not add or remove loop expanders to the fire panel configuration when
the main and backup power supplies are on!
- Connect the connectors: LOOP 2 of the main control panel and LOOP of the second loop controller.
- Fix the second loop expander to the metal box of the fire panel using the supplied bolts in the spare parts
kit.
