Produktdetaljer
Active Loop Panel er en let og kompakt teleslynge-enhed med æstetisk design, der er designet til at supplere typiske samtale-systemer. Den kombinerer alle de afgørende elementer i et funktionelt teleslynge-system, der kun kræver strøm og en lydindgang for at give personer med høretab adgang til lyden.
It comprises an IP rated case, efficient class D loop driver (amplifier), multi-turn copper loop and the internationally recognised signage that informs the user that the service is available.
It designed to be mounted close to an entry intercom or other devices where it can be connected to the audio source via transformer isolated balanced input.
Installation is quick and simple, requiring only the removal of the front cover to reveal the fixing points and quick clamp DC power and line level connections – with only adjustments to current, gain and metal loss compensation being required if necessary when commissioned using a Field Strength Meter (502826) or Loopworks Measure Receiver (502821).
Teleslynge-systemet egner sig til følgende applikationer:
- Door entry intercoms
- Help & information points
- Emergency refuge points
- Information desks & kiosks
Installation Note:
The Active Loop Panel is designed to produce optimal audio quality at bent arm’s length for the average person – as it is expected that they will be depressing a button to communicate via the intercom.
The unit can be mounted below or at the side of the intercom panel at a height of approximately 1.1-1.2 meters (4 feet). At this height, the emitted magnetic field shape will function correctly for both standing adults, children and wheel chair users.
When wall mounting, cabling between the intercom and Active Loop Panel should ideally be routed behind the brickwork to maintain IP rating and finished aesthetics.
Tekniske specifikationer
Power supply and consumption
- 12-24V DC: Typical local DC supply inside equipment where another supply is already present.
- Whilst the HLS-2C draws less than 2.9W @ 12V DC with typical signals, you should still check that an existing supply has enough spare capacity.
Datasheet & Specifications
All information specified on this datasheet has been compiled in accordance with the IEC 62489-1: 2010+A1:2014 Standard and reflects actual performance in realistic applications.
Installation Guide:
Group connections to input 1/2 with DC power cabling. Keep the loop feed cable separate from other connections. When mounting the unit leave clearance above and below the board to meet relevant safety Standards. Mount using 4 x M3 machine screws (with spacers if required) or insulated adhesive pad(s) on the reverse side of the board.
