The Hearing Loop System 1A features a DM1 Induction Loop driver in a steel enclosure. The unit is designed to be integrated into communication systems such as elevators, intercoms, help points and kiosk systems etc. It is backed by Ampetronic’s 5-year warranty and free technical support.
The HLS-1A uses efficient class D current drive technology to reduce power consumption and heat output. It is the only small area induction loop driver capable of reliably driving most practical local area loops to meet the IEC60118-4 Standard even where available power or allowable heat is limited, e.g. connecting to equipment that uses a PoE supply.
The transformer isolated balanced input allows simple connection to all intercoms, help points and kiosk systems, making the HLS-1A the obvious choice for any quality intercom system.
Power supply and consumption
Whilst the HLS-1A draws less than 2.9W @ 12V DC with typical signals, you should still check that any existing supply has enough spare capacity.
The HLS-1A is CE marked to indicate compliance with relevant product safety and EMC standards.
The HLS-1A will allow an Audio Frequency Induction Loop system that meets the requirements of IEC 60118-4 to be created, if the system is specified, installed and commissioned in an appropriate manner, including observing Ampetronic instructions.
Datasheet & Specifications
All information specified on this datasheet has been complied in accordance with the IEC 62489-1: 2010+A1:2014 Standard and reflects actual performance in realistic applications.
Group connections to input 1/2 with DC power cabling. Keep the loop feed cable separate from other connections.When mounting, use appropriately sized screws for your installation application; and washers when necessary. The enclosure has two screw holes, these can be easily accessed by removing the front of the enclosure.
