SPEAKER LINE SURVEILLANCE
Thank you
for choosing another quality product from Amperes Electronics.
LS4808 and LS4816 succeeded their predecessor with totally new circuitry providing major improvements over the perfor-
mance, accuracy and reliability. They now comes with 8 and 16 monitoring channels with simplified setting menus. New
measuring algorithms enables measurement of impedance faster with higher accuracy within a narrow tolerance. Another
new feature included is the remote trigger which can be connected to weekly timer to enable monitoring according to the
preset times.
LS line surveillance unit uses impedance measurement method which allows flexibility in speaker cablings such as branching
and does not require end line resistors or blocking capacitors at the speakers. Its RS485 data output enable remote monitor-
ing and controls via customised software or upcoming PMX III Console.
Prior to installation, we suggest a thorough read through of the manual to get a proper understanding of the unit and what it
can offer. We are pretty sure that you are having a premium product at optimum price for your system.
Please keep this manual for future references.

  • Page 1 Amperes Electronics. LS4808 and LS4816 succeeded their predecessor with totally new circuitry providing major improvements over the perfor- mance, accuracy and reliability. They now comes with 8 and 16 monitoring channels with simplified setting menus. New measuring algorithms enables measurement of impedance faster with higher accuracy within a narrow tolerance.
  • Page 2: Parts Identifications

    The green LED indicates the corresponding channel is normal, whereas red indicates that channel is faulty. 6. 24V DC POWER SUPPLY PORT The unit requires 24V DC power supply and recommended PSU shall be Amperes PS9400. Only use regulated power supply if other than PS9400 is installed.
  • Page 3 Whenever a fault condition is detected, this port shall provide a dry contact to link to external alerting devices, such as mimic panel, etc. 10. RS485 OUTPUT (OPTIONAL) Event triggered data shall be transmitted with RS485 protocol. LS4808 / LS4816 | 8 / 16 CHANNEL SPEAKER LINE SURVEILLANCE PAGE 3...
  • Page 4 It is recommended that periodical manual checking or setup to be made as connections may deteriorate over time and thus affecting overall impedance value. PAGE 4 LS4808 / LS4816 | 8 / 16 CHANNEL SPEAKER LINE SURVEILLANCE...
  • Page 5: Connecting The Unit

    Surveillance’. The red LEDs shall lit in sequence indicating sequence of initiali- sation. ENTER MENU NEXT TO ENTER SETUP To begin programming, press MENU button, and the SETUP menu shall be displayed. LS4808 / LS4816 | 8 / 16 CHANNEL SPEAKER LINE SURVEILLANCE PAGE 5...
  • Page 6: Setup Menu

    Note: In long cable circuit or zone with multiple branchings the basic mode may not be suitable to detect the fault such as short at the far end of cable (e.g: 500m), cables itself has resistance, thereby would not show short phenomena. It is therefore, Advance setup shall be used. PAGE 6 LS4808 / LS4816 | 8 / 16 CHANNEL SPEAKER LINE SURVEILLANCE...
  • Page 7 The limits are typically 15%, eg if the circuit has impedance of 1K Ω, the limits generated shall be 850 to 1.15K Ω. LS4808 / LS4816 | 8 / 16 CHANNEL SPEAKER LINE SURVEILLANCE PAGE 7...
  • Page 8: Manual Test

    If a test interval is selected ( from 1 min - 24 hour ). By default, auto mode is set to off. INTERVAL: 01 MIN Use NEXT / PREV button to select time. ENTER MAIN MENU 3. AUTO TEST PAGE 8 LS4808 / LS4816 | 8 / 16 CHANNEL SPEAKER LINE SURVEILLANCE...
  • Page 9 LS4808 / 4816 are used to detect faulty speaker circuits and the impedance measured shall not be used as final value / reading as conclusions. The actual reading may differ from actual impedance meter in range of 5%. LS4808 / LS4816 | 8 / 16 CHANNEL SPEAKER LINE SURVEILLANCE PAGE 9...
  • Page 10 LS4808 / 4816 has unique way to detect faults, there by using basic mode, creating an impedance limit range and for more sensitive detection, set the unit to ‘advance’ mode. PAGE 10 LS4808 / LS4816 | 8 / 16 CHANNEL SPEAKER LINE SURVEILLANCE...
