Hörmann HNA 18-3 emergency battery

During a power failure, a garage door operator does not work. The Hörmann HNA 18-3 emergency battery powers it for up to 18 hours and can handle up to 5 door cycles in that time. Battery life depends on the temperature and state of charge. While running on the battery, the operator lighting does not come on. Once power is restored, the battery recharges itself. It has protection rating IP20 and belongs in a dry garage only.

Which operators it fits

• Series 2 and 3 – SupraMatic, ProMatic and RollMatic.
• Series 4 – choose the HNA 18-4.
• Entrance gates – choose the HNA Outdoor.

Installation and checks

1. Unplug the operator from the socket.
2. Fix the battery to the operator or to the ceiling so that the yellow LED is visible.
3. Push the cable connector into the operator plug. Observe the polarity, otherwise the battery will not work.
4. Plug the operator into the socket. The orange LED means mains voltage is present and the battery is charging. Full charging takes no more than 48 hours; test the function only afterwards.
5. Every 3 months, disconnect the operator from the mains and run 2–3 complete door cycles. The operator may run more slowly.

Do not leave a disconnected battery uncharged for more than 1 month. Send questions about compatibility to eshop@saver.sk.
