2.                     Execution

2.1                   GENERAL

• Be sure you have set the right address to each device.  There should exist in total 250 unique addresses per loop.

• It is essential to draw a schematic of the complete installation. The schematic must include cable length, cable cross section, and the location of each device. This will be useful to locate where a fault or a shortcut occurs.

• If the cable loop passes near a motor or mechanical ballasts or other devices which does not comply to CE in radiation activity, then a shielded cable is needed.

• Always observe polarity throughout. Ensure circuit polarity requirements have been met.

• Non color coded conductors should be identified (e.g. with labels).

• Examine all electrical connections to every device to ensure supervisory circuits, where provided, function as intended.

• Ensure all conductors have been individually terminated in an approved manner.

• Check all devices for tampering or damage that may affect their operation.

• Test equipment with capability for field adjustment to ensure adjustment is compatible with expected hazard conditions.

• Operate every luminary test button for its good operational condition.

• Check installation of every device to ensure no architectural, mechanical or environmental features can prevent any device from operating normally. Devices should be located correctly and should also be accessible for maintenance.

2.2              WIRING VERIFICATION

Steps to verify the integrity of the installation’s wiring:

1. Verify the mains power supply to the panel and the connection of the protective earth (PE) to the board terminals. The panel should be supplied by a separate line with its own circuit-breaker.
2. Using a multimeter measure the resistance between the protective earth (PE) terminal and the panel’s earth bar. It should be less than 10 Ω. Higher values indicate bad panel grounding, and it is highly dangerous and unsafe to operate it.
3. Optical inspection of each cable for possible wear/damage caused during the installation.
4. Optical inspection of each point connection for bad/wrong wiring.
5. If points are connected using a loop topology, using a multimeter measure the resistance between each L+ and its corresponding LF+ line. It should be less than 60 Ω.  Higher values indicate faulty connections/cable and should be investigated and resolved.
6. If points are connected using a loop topology, repeat the previous step for loop cable, each L- and its corresponding LF- line and each shield line start-finish.
7. If points are not connected using a loop topology (no return line), connect temporally the L-, L+ and its shield, at the last point (end of line) together. Using a multimeter measure the resistance between the start of L- and L+ line. It should be less than 60 Ω.  Higher values indicate bad connections/faulty cable and should be investigated.
8. If points are not connected using a loop topology, repeat the previous step for the L- or L+ line and its shield. IMPORTANT: Remove the temporal connection at the end of the line between L-, L+ and its shield.
9. Using a multimeter measure the resistance between each L+ and its corresponding L- line. It should be more than 10kΩ. Lower values indicate faulty connections/cable/short circuits and should be investigated and resolved.
10. Using a multimeter measure the resistance between each L+ and its corresponding shield line. There should be no circuit continuity (at least 10MΩ). Lower values indicate faulty connections/cable/short circuits and should be investigated and resolved.
11. Repeat the previous step between each L- and its corresponding shield line, each L+ and the protective earth (PE) line and each L- and the protective earth (PE) line.
12. Every time a problem is detected and corrected on a line, all the check for this line should be repeated from the start.

2.3               SYSTEM COMPONENTS MAINTENANCE

Addressable Luminaries:

• Test manually each luminary for intended function in accordance with Olympia Electronics instructions.

• Operational tests can be scheduled by the user via the safety lights control panel.  Function test is normally scheduled to all luminaries of the panel once a day, whereas, Duration test is scheduled once or twice per year.  At the end of each test the panel records the faulty results (if any). 

• During maintenance apply further tests on each luminary using the safety lights control panel.  Tests will result in a failure signal in case of a particular luminary malfunction. 

1. Communication test (from the Technician menu enter the CHECK menu and select POINT to monitor good and bad communication packets.  Only good packets should be increasing indicating good communication of each luminary with the panel)
2. Function Test (from the Technician menu enter the TEST mode and select START FUNCTION TEST for each luminary and optically monitor lamp performance and ensure its intended function)
3. Duration Test (from the Technician menu enter the TEST mode and select START DURATION TEST to send a command to a particularly luminary.  This process will force the luminary battery to discharge completely and may take several hours to complete.  It is therefore advisable to send a command to all luminaries and wait till process is completed until panel lists the number of luminaries with faulty batteries)

Power Supplies:

• Ensure normal and emergency power supply operates at nominal voltage and frequency values within permitted declinations.  

• Ensure that the power supply of the safety lights control panel system can be disconnected only by the appropriate fuse or breaker which serves the system.

• Proceed to a random check for good operation of different luminaries while they are power supplied by back up source.

Generator Standby Power:

After disconnection of building main power supply, ensure emergency generator starts automatically within 15 seconds. Also ensure the main panels’ good operation under generators main power supply.

A-986, 2x 12V/7-15Ah Main unit standby batteries:

Examine optically batteries for good looking condition. Main unit batteries should not be swollen or corroded.

The batteries used must be 2x 12V (7-15Ah) Lead Acid with a rating of 12V. Replace batteries with batteries of the same type and rating.  

Ensure that the batteries mounting metal parts have been installed in order to prevent vibrations problems. The metal brackets must be always fitted according to LPCD approval.

GR-750X Safety Lights Addressable Control Panel:

• Visually check the safety lights system control unit.  Ensure control unit has not been altered or tampered with.

• Visually and physical inspect all cables, plug interconnections, plug-in circuit components, leds, sockets and controls.

• Ensure associated mechanical and electrical connections and mounting are as required for intended function.

• Test all lamps and indicators for operation and intended function, by entering the Test mode menu of the panel and select Test LED function.

• Operate all control unit functions to verify appropriate response.

Ancillary Devices:

• Check all ancillary functions, eg. system activation signals from relays or input signals to relays

• Ensure any faults in ancillary equipment will not interfere with normal operation of safety lights control panel system.
