INSTRUCTION MANUAL

LS4600Speaker Line Surveillance

VER 3 / 2015

LS4600 was produced out of extensive research and development effort in which every aspect of line surveillance require-ments are studied. It solves the problem faced by many installers using the conventional line monitoring method, by adopt-ing impedance measurement methodology. This shall eliminate the needs to add coupling capacitors to every speakers, rigid cabling rules as well as inaccuracy in detection. Thereby, LS4600 allows branching in cabling works, direct tapping of line to speakers as well as easier setup, without having to trim impedance against a preset reference.

LS4600 is built and run by a micro-controller , thus providing a digital platform in setting up your system. User can set various parameters by following the menu displayed in the LCD screen. Among them shall be the high and low limits, buzzer on / off, display backlight, monitoring setup time, auto or manual mode as well as doing manual testing.

It shall not be difficult to understand or to install the unit, but it is recommended that a trained personnel is engaged in order to tap the many features available. Before installation, we suggest a thorough read through of the manual is done to avoid any unnecessary damage to your setup.

Please keep this manual handy for any future references.

2 x 16 digit LCD display with back light setting is used as programming guide as well as measurement indications. The back light can be set to off if required by accessing menu 6 (see programming chart). The back light is set to ON in default.

Menu switch is used to access main menus. Once pressed momentarily, it shall revert to Menu 1.0 - Setup. Use Next and Prev keys to scroll through other main menus. Once the relevant menu is found, use Enter key to access its following sub menu. To exit sub menus, press Menu key momentararily.

Used to enter required main menu or its sub menus, confirm values, data or settings.

The arrays of green LEDs provides the status of the channel which show the normal condition if lit. If both green and red LEDs do not lit for the particular channel, it means that the channel has been bypassed from monitoring.

Once lit, it indicates that the particular channel is at fault ; either open, short or leakage. Refer to the LCD panel for exact condition of fault.

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.

9. 24V DC POWER SUPPLY PORT

If fault is detected, a buzzing sound shall be emitted with the LED lit. Buzzer alert can be turned off via programming and this is indicated by this LED.

8. BUZZER LED

When line monitoring is initiated either manually or auto, it shall start in sequence from ch.1 to 6. With each channel under monitoring, a dry contact shall be available at its correspondence zone. This shall provide 24V overriding voltage to volume controllers or local patch panel with overriding relay, thus allowing direct measurement to the speakers. (Refer to Connecting the unit section of the manual). Overriding is required for accurate sensing in which volume controllers set in various position shall have different impedances and such circumstances shall provide false alarm or alert.

Recommended practice is that every zone shall have its own 24V overriding circuit back to the rack. If all the overriding circuits are looped, and if the particular zone with volume controller is set to off, the monitoring activity shall cause a burst of audio signal (such as BGM), which lasted for approximately 18 seconds. This shall happen only when a BGM source is presence. If the particular zone is set to OFF (without BGM), the monitoring activity shall not emit audible sound.

10. ZONE TRIGGER OUTPUT PORT

It is for connections of incoming 100V line signal and output to speakers. Refer to Connecting the Unit in following section.

11. AMP / ZONE IN - OUT PORTS

Whenever a fault condition is detected, this port shall provide a dry contact to link to external alerting devices, such as mimic panel, etc.

12. OUTPUT FAULT CONTACT

Event triggered data shall be transmitted with RS485 protocol. This feature is optional and shall be available in future.

The LS4600 detects circuit faults using impedance measurement method. In general, there is no limitation on how the external cabling to speakers or volume controller are run, ie. branching is allow and does not need end line resistors as well as speaker capacitor couplings.

LS4600 have been improve all accuracy. It is recommended that periodical manual checking or setup to be made as connections may deteriorate over time and thus affecting overall impedance value.

Only 4 wire system is suitable for measurement. 3 wire system may cause undesirable result each time checking is being made due to the presence of volume controllers.

It is recommended that separate zone shall have separate overriding circuit. Otherwise, loop all outputs. Disadvantage of looping all outputs : If a particular zone is active (zone on) but the volume controller at a certain area is shut off (eg. zone 1), activation of monitor-ing from LS4600 of zone 2 shall override the volume controllers at zone 1, thus a burst of audio shall be heard ( such as BGM being currently played).
