19� Loop Fault – remote output monitor connection; Monitors the function of the system� Whenever there is an inconsistency of the system a fault signal triggers relay contacts to: OPEN RELAY = FAULT CLOSED RELAY (short circuit) = OK B. INPUT 3 (PHOENIX SCREW TERMINAL/RCA) 20�...
Installation Planning Calculations for coverage area, metal loss, signal sources, power outlets, dissipating heat and ventilation for loop driver placement and other practical installation issues, must be done prior to the on-site installation� Please refer to www.univox.eu/planning Use Univox Loop Designer (ULD), a free, web-based project planning and design software for easy and accurate assistance in designing loop systems�...
Placement of the microphones Microphone placement and proximity between microphone and mouth is crucial for improved speech intelligibility� Use shortest distance possible between microphone and mouth/sound source� Commissioning and certification Check the system when the installation is completed� Properly installed systems should meet the requirements for field strength, consistency and frequency response according to the international standard IEC 60118-4�...
System setup Start-up procedure 1� Each loop must be securely isolated (particularly to safety-ground and other loop connections)� Verify the resistance of each loop (approximately 1-3 Ω) (21/25/29) (14) 2� Connect the input and output connections • SLS model: Connect Master and Slave loop cables. The Master loop cable connects to loop terminal screws 1 and 2�...
Output connection and adjustments 12� Field strength setting: Start with the highest efficiency connection, I) 2-turn serial connection� For loop connection use a junction box, see the diagram below� 13� Set field strength in range -3 dB to 0 dB at the peaks� If Peak LED flickers occasionally the connection is acceptable�...
Note: To quickly set up the field strength for a programme material, a PPM instrument, like the Univox Listener can be helpful� The Univox Listener has a calibrated level indicator that quickly detects the highest peak� Note: The field strength peaks should be adjusted to -2 dB field to suit dynamic headroom in various hearing aids 14�...
Troubleshooting Symptom Possible cause Solution General malfunction Check the system with the start-up procedure� See page 10� Loop fault LED On No input signal Check the input signal No output signal Both master and slave loop must be connected Loop not connected properly Check the loop connection Power LED is off Power supply not connected...
