Product
• The control unit is designed for the automatic opening of VELUX staircase smoke exhausts without or with exit CSJ 1210
and CSJ 1211 respectively. Check whether the system complies with the applicable regulations. Connection to other prod-
ucts may cause damage or malfunction.

• When installed, the control unit complies with protection degree IP 30.
• The packaging must be disposed of in accordance with national regulations.
• The product, including batteries if any, is regarded as electrical and electronic equipment and contains hazardous materi-
als, components and substances. The crossed out wheeled bin symbolises that electrical and electronic equipment waste
must not be disposed of together with household waste. It must be collected separately at recycling stations or other
collection sites or retrieved directly from households to increase the possibilities of recycling, reuse and utilisation of elec-
trical and electronic equipment waste. By sorting electrical and electronic equipment waste with this symbol, you con-
tribute to reducing the volume of incinerated or buried waste and to reducing any negative impact on human health and
the environment. Further information can be obtained from the local municipality's technical administration or from your
VELUX sales company.
• If batteries can be removed, product and batteries must be disposed of separately.
• If the staircase smoke exhaust is exposed to high wind loads, it is recommended to connect the control unit to a wind
sensor that automatically closes the staircase smoke exhaust.
Installation
• The control unit must be connected directly to the mains supply in accordance with national regulations. Ensure that the
mains supply cannot be disconnected unintentionally. It is recommended that disconnection is only possible using the
mains switch or a key switch. At least one of these means for disconnection must be incorporated in the fixed wiring in
accordance with national wiring requirements.
• Protect the 230 V AC mains connection cable separately on site.
• Cable types, lengths and cross-sections must be in accordance with the technical specifications.
• All low-voltage cables (24 V DC) must be routed separately from the high-voltage cables.
Maintenance and service
• Disconnect mains supply and back-up batteries before carrying out any maintenance or service work to the control unit
and ensure that they cannot be reconnected unintentionally.
• The control unit must be tested after installation, service work and alterations to the system. It must be inspected by quali-
fied personnel at least once a year. Tests and inspections must be documented in accordance with national regulations.
• Use only original spare parts.
• At the yearly inspection, the connected products must be checked according to their instructions.
• The printed circuit board monitors the time between inspection periods. If more than 15 months have passed since the
last inspection, the yellow light-emitting diode is on and an acoustic alarm sound.
• The batteries must be checked at the yearly inspection. We recommend that the batteries are replaced at least every four
years.
