BATTERY STORAGE/CARE DETAILS

Optimal storage conditions (when not in service and batteries disconnected)

• NiCd +5°C to 25°C (6 months onsite maximum)
• NiMh +5°C to 25°C (3 months onsite maximum)
• LiFEP04 +5°C to 25°C (6 months onsite maximum)
  Old batteries must be handled and disposed of by specialist disposal experts. Under no circumstances should they be pierced or incinerated.
  Do not put the luminaire into emergency mode until the batteries are fully charged

MAIN CAUSES FOR PREMATURE BATTERY FAILURE:

1. Over cycling of batteries for example caused by an unstable mains supply. Batteries are designed to carry out 3 – 4 full discharges per year. Over cycling will reduce the capacity and hence life.
2. Leaving connected batteries in a discharged state (maximum 2 weeks).
3. High ambient temperatures (greater than the ambient specified by Whitecroft lighting)
4. Repeated partial discharging and recharging of batteries (memory effect)

EMERGENCY SUPPLIES

• Power to energise emergency luminaires can come from integral batteries within the luminaire (self-contained) or from a remote Central Battery system or Static Inverter. This power supply is intended to energise the emergency circuit within any emergency luminaire upon failure of the normal supply.
• Integral battery emergency luminaires indicate ‘batteries are charging’ generally by use of an indicator LED mounted in a visible location on the luminaire. When the indicator LED is solid green, the batteries are charging.
• Emergency luminaires generally have internal supply connections: Permanent Live (orange), Switched Live (brown), Neutral (blue), and Earth (green/yellow).

TESTING REGIME

As detailed in BSEN50172:2004 (BS5266-8:2004)

• Monthly function test (30s) to check luminaires are functioning correctly (unless detailed differently in commissioning procedure)
• Annually full duration test to check the luminaires are functioning correctly and meet their full duration
• Emergency testing results must be documented and be available for inspection.

FAULT FINDING

• Inspection / fault finding work must be carried out by a suitably electrically qualified person.

• Initial checks must include continuity of fuses and integrity of internal/external wiring.

• Please read BATTERY STORAGE/CARE details in this leaflet before continuing.
  CAUTION: Even if the power supply to the emergency luminaire may be disconnected, there may still be high voltages inside the fitting. Disconnect batteries when maintaining internal wiring.

  • LED indicator non-operational and does not work in Emergency mode.
  1. Check that the permanent 230v supply is present in the luminaire.
  2. Check the batteries are properly connected.
  3. Replace the batteries with known working units.
  4. Replace the inverter ensuring you change it ‘wire for wire’.
  5. If the luminaire still does not function please call Whitecroft Technical.
  • Luminaire functions in Emergency mode but will not function in Standard mode.
  1. Check that the Switched Live is present.
  2. Check that the Switched and Permanent Supplies are correctly connected.
  3. Check that there is 230v at the ‘Live Out’ terminal of the emergency inverter.

EMERGENCY LUMINAIRE COMMISSIONING

Battery activation

• For new NiCd, NiMh & LiFEP04 batteries activation of the cell is required to ensure specified design life.
• If the emergency luminaire does not pass the initial 3hr duration test a further full charge and discharge cycle may be required to activate the battery chemistry.

PROCEDURE

• STANDARD EMERGENCY

1. Connect the battery once a stable mains supply is present
2. Allow the battery to charge for a period of 24hrs
3. Perform a full manual discharge test (minimum 3 hrs.)
4. If the emergency luminaire does not pass the initial 3hr duration test a further full charge and duration test (this test can be used as the scheduled EM test)
5. If the luminaire does not pass 3 hour test contact Whitecroft Technical for assistance.

• EASY-TEST/SELF-TEST

1. Connect the battery once a stable mains supply is present
2. Allow the emergency luminaire to complete its self-commissioning phase which charges the battery for 24hrs, followed by a 3hr duration test.  

If the luminaire successfully completes this test, the indicator LED will be solid green

3. If the emergency luminaire does not pass the initial 3hr duration test, allow the battery to charge a further 24hrs and then do a manual 3hr duration test
4. If the luminaire fails this duration test then contact Whitecroft Technical for assistance

• DALI TEST

1. Connect the battery once a stable mains supply is present
2. Allow the emergency luminaire to complete its self-commissioning phase which charges the battery for 24hrs, followed by a 3hr duration test.  

If the luminaire successfully completes this test, the indicator LED will be solid green OR if a DALI bus is connected and the luminaire has been commissioned the self-commissioning duration test can be stopped and a scheduled duration test can be performed using DALI commands.

3. If the emergency luminaire does not pass the 3hr duration test, allow the battery to charge a further 24hrs and then do a manual 3hr duration test
4. If the luminaire fails this duration test then contact Whitecroft Technical for assistance.

EMERGENCY COMEPS DALI TEST

Application

• Low profile emergency lighting module with DALI interface and automatic testing facility to cover 3 hour duration operating from batteries.
• DALI interface terminals are provided to allow control and monitoring via a separate controller. With no DALI bus connected the unit operates in self-test mode with testing being conducted on a weekly functional and 52 week duration basis with adaptive duration testing feature to minimise risk.
• Fitted with the unique easy addressing feature which uses the LED to indicate the DALI address during commissioning.

Monitoring

• DALI interface for controlled monitoring and reporting.
• During operation the battery, lamp and charge conditions are monitored along with functional and duration testing.
• In the event of failure the bi-coloured LED will indicate the nature of the fault. This it will continue to do until the fault has been remedied. The testing regime will then continue.

Testing
When a DALI bus is not connected or when a command has not been received the COMEPS will operate in the self testing mode and will conduct tests in accordance with the default times stored in the EEPROM. However it should be noted that in this case the delay time is set as default zero and all units could test at the same time. Test times can be changed with a command over the DALI bus.

Addressing
The COMEPS includes the easy addressing system which allows addressing and identification by using the bi-colour LED in conjunction with the COMEPS ADDRESS tool. Binary address codes given by the LED can be simply converted to the DALI addresses 0 to 63. For single handed addressing using this method it is necessary to send a broadcast ident command every 3 to 9 seconds. During this command the main fluorescent lamp will be switched off and the LED will flash the 6 bit binary address preceded by a 3 second start indication period.

Functional test
The time of day and frequency of the 30 seconds function test can be set by the DALI controller. If the COMEPS unit is not connected to a DALI bus or has not received a DALI command the test will default to 30 seconds duration on a weekly basis.

Duration test
Test times can be set by the DALI controller. If the COMEPS unit is not connected to a DALI bus or has not received a DALI command the test will be conducted every 52 weeks.

Prolong time
Prolong time can be set by the DALI controller. This is the delay time between return of the mains supply and the end of the emergency operation. The default prolong time is set as 0 minutes as specified within the DALI standard.

Battery
Recommended charge time is min. 24h. Battery should be fully charged before any emergency tests are performed.

DALI LUMINARES CONNECTIONS FOR COMEPS AND DALI LUMINAIRES
Note: It is imperative to add the links shown below if using DALI dimming and emergency test on the same addressable control circuit.

ORGANIC RESPONSE LUMINAIRE WITH COMEPS (DALI) LUMINAIRE CONNECTIONS
The luminaire is supplied with terminal connections for both the COMEPS inverter and Organic Response node. The Organic response terminal are supplied with the connections blocked to stop inadvertent connection. If the luminaire is to be used for emergency reporting on the Organic Response Portal system, then the terminations should be unblocked and connected as below.

EASY TEST

Application
Whitecroft Easytest is an intelligent testing system, which can monitor and test self-contained emergency lighting luminaires.
The system tests luminaires in line with current legislation for self- contained non-maintained emergency applications with battery duration up to 3 hours.

Intelligence
The easytest unit is a stand-alone intelligent module, which can be integrated into virtually any Whitecroft emergency luminaire.
Each intelligent luminaire has EITHER a bi-coloured LED OR TWO LED’s to indicate unit ‘on test’ or ‘failure’ diagnostic information in addition to ‘battery charging’.

Monitoring
During operation the battery, lamp and charge conditions are monitored along with functional and duration testing.
In the event of failure the LED (s) will indicate the nature of the fault until the fault has been remedied. The testing regime will then continue.

AUTOMATIC TESTING

• Commissioning Test
  A full commissioning test is carried out automatically after permanent connection of the supply. The easy commissioning feature will set the initial test day and time to ensure random testing of units.

• Functional Test
  Functional tests are carried out for 30 seconds on a weekly basis.

• Duration Test
  A full duration test is carried out yearly to check the capacity of the batteries.

NOTE : IEC 60073 recommends that the charge indicator LED should be Green to indicate System OK. The above table conforms to those recommendations.
It is possible to reverse the bi-colour LED connections to swap Green and Red indications and it is also possible to have an alternative Red + Amber LED pair for compatibility with earlier product.

WIRE ROPE SUSPENSION

• Installation of Wire Rope Suspension System of Luminaires
• Whitecroft Lighting luminaires must be installaed in accordance with the relevent installation instruction and as guidance the latest version of BSRIA Code of Practice 22 – Wipe Rope Suspension Systems.
• Do not use the wire suspension to raise or lower the luminaire during installation as this may result in damage to the clutch mechanism.
• The clutch should only be adjusted when supported and under no mechanical load.
