ACTIVATION
The labelling informs you of the various options available for the damper.
1
TRIGGERING
- Manually: actuating the white lever on the side, without removing the cover.
- Automatically controlled: any temperature above 70°C trips the fuse mounted on all ISONE + (obligation under
NF S 61-937-5 and NF EN 1366-2).
- Remotely: depending on the initial choice of type of dual-voltage electromagnet, the making or breaking of a current
circuit (24 or 48 Vdc) will trigger the damper to move to its 'safe' position.
RESET
2
With the damper in its 'safe' position (closed), it can be reset either:
- manually, using a screwdriver without removing the cover,
- remotely, by energizing the reset motor. The motor stops automatically once the maximum torque level has been
reached. It is recommended that you disconnect the power supply to the motor after 30 seconds.

INDICATORS
The closed position contacts (FCU) indicate the safety position of the damper (i.e. closed), the open position contacts
(DCU) indicate the standby position (open).
These contacts are illustrated as inactive, use the NO terminals on the contacts (1 & 3, 4 & 6, 11 & 13, 14
and16) to close a signalling circuit (or light indicator lamps for example).

GENERAL INFORMATION
All power supplies connected to the circular ISONE + damper mechanism must be VLSV (very low safety voltage).
All connections must use disconnectable plugs (supplied).
Contacts are shown on standby.
There are three types of connection board depending on the options chosen (see damper label). All three boards
can be unclipped without tools. Boards 1 and 2 are interchangeable.
BOARD No. 1 - FCU1 - DCU1
2
ISONE + thermal fuse link
Possible options: open/closed position contacts
FCU1 and/or DCU1:
NO/NC inverter contacts
Contacts are
Breaking current = 3A max. under 48 Vdc
illustrated on standby

BOARD No. 2: ELECTROMAGNET / MOTOR
ISONE + thermal fuse link
Possible options: - End & start of travel contacts
- Electromagnetic trigger
- Reset motor
FCU1 and/or DCU1:
NO/NC inverter contacts
Breaking current = 3A max. under 48 Vdc
Electromagnetic trigger fitted with three-wire dual-voltage
electromagnet; the voltage is factory pre-set in accordance with
the customer's order and can be modified by a switch (see diagram).
The electromagnets are: - emission activated: Un = 24 or 48 Vdc (-15%/+20%) - P max. = 3.5 W.
- breaking activated: Un = 24 or 48 Vdc (-15%/+20%) - P max = 1.5 W.
Caution, the choice of either emission or breaking activation must be made when ordering the damper.
EHOP 30s reset motor: Multi-voltage from 24 to 48 V ac or dc (±10%) - I max. 0.7 A.

MISE EN GARDE
STORAGE PRIOR TO INSTALLATION
These devices should be stored in an enclosed, dry and frost-protected location, away from the weather. They should not be
stacked any higher than the original factory packaging. They should be arranged to prevent damage to mechanisms of moving
parts, and to avoid deformations of the device body due to excess loads or humidity. Do not leave dampers exposed to direct
sunlight as this will cause premature ageing of the fuse.
PROTECTING THE EQUIPMENT DURING INSTALLATION
Although the fire damper, and more particularly its mechanism, is protected by a synthetic material cover, it should be
protected from projections of any kind (mortar, paint, sprayed cladding, etc.) that may affect the operation of the trip devices
and signalling devices.
The equipment should also be protected against the risk of water run-off or high condensation, both for the refractory part and
the metal parts, or electromagnetic components.
The airtight intumsecent seals are primordial for the damper's fire resistance, so any mechanical actions on the refractory
parts should be avoided.
All suitable precautions should be taken to prevent premature ageing of the equipment before it is put into service on completed
Wedging and filling in order to seal devices in place correctly should not cause deformations likely to adversely affect the
operation of the fire damper.
INSPECTION OF THE EQUIPMENT PRIOR TO INSTALLATION COMMISSIONING
Dampers should be maintained in mechanical standby position before the ventilation systems are effectively put into service,
so as not to apply forces to the retention devices or trip devices until the normal operating conditions are met.
