Auto Addressing by Isolators
. This way requires all of the devices connected to the line to have a built-in or
connected to the loop isolator module. The panel starts automatically setting address to the devices in increasing order
from 1 to 250 by following the sequence of their position on the line.
The direction of auto-addressing procedure, according the positive and negative lines of the 41CPE112 Loop
expander, is shown on the next connection diagram:
During the auto-addressing procedure the panel begins to address the devices in the loop one-by-one starting from right positive
and negative lines of Loop following the direction to the right. The addresses in the possible branches on the loop continue the
address numbers from the main line to the end of the branch. Then the address numbering continues on the main line and so on.
7.4.1 Set Address
In this submenu the installer can directly set addresses to new devices in the system. The procedure is same with that
for self addressing. It is suitable when the installer needs to add single devices to the system configuration at free
addresses. The detectors and sounders must not be mounted to the bases; the call points and modules must not be
connected to the loop.
To set address to a device, enter in the installer’s menu - 4. ADDRESSING - 4.1. SET ADDRESS. The device must be
prepared for connection to the panel (loop 1 or loop 2).
The system automatically shows the first address in the system. Use the button ‘CHANGE’ to switch to loop 2 if present
in the system
. The address is free if ‘SAVE’ button is active.
To find a free address use the up and down arrows to scroll over the address numbers.
The free address in the system configuration is recognized with active ‘SAVE’ functional button (2) in the last row of the
screen. Take the new device and connect it to the system - mount the detector or siren to the base or connect the
module to the loop. Press the ‘SAVE’ button and wait for a couple of seconds. If the addressing is successful the
message ‘SUCCESSFUL’ starts blinking on the screen. If the message is ‘ERROR’ then there is a problem - the device
is not properly connected; there is no communication with the panel. You can proceed with setting the next address or
escape with ‘CANCEL’ button.
