Addressable Fire Panel MAGPRO96
- Installation and Programming Manual
2.2.5 Loop Expander
The MAGPRO96 fire panel operates with MAGPRO96-L250 loop controller (
MAGPRO communication protocol
).
The Loop Controller (Figure 14) realizes the connection between the I/O Module and devices connected to the com
-
munication line. The Loop Expander has two basic functions: 1. Gathers data from the devices in the communication
line and transfers it to the I/O Module; 2. Receives commands from the I/O Module and transfers them to the devices
connected in the communication line.
Every MAGPRO96-L250 Loop
provides up to 250 devices.
The maximum current consumption of the devices in the communication line is I
max
= 500mA. If the consumption ex
-
ceeds this value an over-load protection would be turned on.
In the configuration of analogue-addressable fire panel MAGPRO96 could be mounted up to 4 loop controllers.

ATTENTION:
DO NOT ADD OR REMOvE LOOP ExPANDERS to the fire panel configuration WHEN
THE MAIN AND bACkuP POWER SuPPLIES ARE ON

1
- Connect the interface connectors of the first and the second loop expanders.
2
- Fix the second loop expander with supplied bolts in the kit to the metal box of the fire panel.

Note:
The method of adding third and forth loop expander is analogical to that shown on Fig. 15.
