Amperes LS4816 16 ch Speaker Line Surveillance

Product Details:
LS4816 is new speaker line monitoring unit, with the new processor and measurement algorithm, they are now able to perform tasks faster with better accuracy. Additional features included were trigger monitoring, which can be linked to timer for pre-set times activation. Similar to its previous model, they provide reliable speaker circuit monitoring for ground leakage, short and open circuit using impedance measurement method, thus eliminating the use of blocking capacitors and end line resistors. 

Features:

• Basic and advance level setting
• Sensitivity setting
• Impedance measurement method ; end line resistors, block capacitors not required
• Faulty circuit disconnection option
• Built in impedance meter ; 10 to 10K Ohm
• Fault alert bicolour LED with buzzer
• Interval detection from 1m to 48 hrs
• Remote detection activation
• Short burst signal for lesser interruption
• Aux contact for 24V overriding ​
