Motorized fire dampers electical wiring
To connect the dampers to the power supply, proceed as follows:
• Check that the voltage and electrical frequency are equivalent to
those of the motor of the servomotor (check the motor’s informa-
tion label);
• Make the connections as shown in the below diagram.

MAINTENANCE AND INSPEC TIONS
The MP3 fire dampers don’t need maintenance.
Periodic inspection
The damper inspection must be done according to national law.
The periodic inspection must be according to EN 15423 annex C and
EN 15650 annex D.
When a remote control system, such as a smoke or other alarm sig-
nal, is used to close fire dampers, the correct working of such alarm
signals must be tested during the periodic maintenance and check
of the full fire safety system.
Disposal
Disposal in case of destruction must be carried out in accordance
with national legislation. For electrical and electronic parts also refer
to EU Directive 2011/65.
INSTALLATION
The sizes shown are in mm.
