Any modification on the dip-switches requires
the storage of the relevant configuration also in
the control panel (CONFIGURE REMOTE
DEVICE menu).
ADDRESSING
The address (1-128) is software set and stored
in a non-volatile memory.
The module can be addressed, in manual or
automatic mode from the control panel.
For further details see the control panel's
programming manual.
CONNECTIONS
Detection circuit:
A shielded cable must be used; connect the
shield of the cable (one end in a loop mode) to
the ground in the control panel only and connect
the shield between a device.
The section of leads can vary according to the
length of the detection line.
A lead section of 1.5 mm
Don't use cable that exceed these limits:
Maximum resistance = 100 Ω
Maximum capacitance = 2 µF
Power supply module:
A lead section of 1.5 mm
module powers and handles the detector.
4-20mA detector:
A shielded cable must be used; connect the
shield of the cable to the shield of the detector
circuit near to the module; leave the other end
open. A lead section of 0.75 mm
The connection must not exceed 10 m of length.

TESTING (trained personnel)
Before testing, notify to competent authority that
the system is temporarily out of service due to
maintenance operations.
The module and the detector can be tested
using a specific tools as indicate by the
manufacturer of the detector.
At the end of testing operations, restore the
system to normal operation and notify the status
to the competent authorities.
