About this deal

When using self testing hardware (with each light running on a separate circuit) do I still need to be able manually switch off the power to each unit independently or can I rely solely on the self test feature to comply with BS 5266?

Yes, the key switch is to allow for manual testing and self testing luminaires are automatic therefore you do not require key switches. Annually you need to switch off the mains power supply to the emergency lighting units and then leave the units illuminated for a longer period (usually three hours). However if you are concerned the enforcing authority is the local Fire and Rescue Service (FRS) and you should contact them. Could anyone explain what i would need to have done to conform, I have a building with 1 key switch in the reception for the Em fitting Test the rest of the Em fittings in the Building are a self maintained type. So without knowing further information it is not possible to suggest where test switches should be located.

High risk task area lighting is provided predominantly to ensure that processes can be safely terminated, and occupants make their evacuation from the area without undue risk from the process. Self testing EM lights also have multiple coloured LEDs and a "beeper" and problems or potential problems are indicated by the sequence / colour of the LED's and beeper. In a system with a single switch for the entirety of the building or a large circuit, it is important for the responsible person to walk the entirety of the building or circuit to check that all the lights are working correctly and that there are no signs of damage to the light fitting. The Eaton F9099 Emergency Lighting Test Key is designed for use with the Eaton range of grid switch emergency lighting test switches.

When carrying out an emergency lighting test, a mains power failure (power cut) on the normal lighting circuit/circuits or individual luminaries must be simulated.

The test switch is a safe way to cause a permanent mains failure to the emergency fittings for both the monthly function test and annual duration test. A minimum duration of 3 hours should be used for emergency escape lighting if the premises are not evacuated immediately. In general, after installation and power up the software starts, 24 hours later the light will carry out a 3 hour duration test, after that it will change to a 30 second test (To establish if the light will illuminate on battery power) once a month, it will start the whole sequence from the beginning 12 months later, as said previously, if any problem is detected then a LED / beeper / sequence will initiate. During this period the light levels will be a lower level of illumination when in emergency mode and depending how long it would take you to walk the emergency lights would it be safe for the relevant persons occupying the building?

I have an electrician telling me I have to have a key switch to turn off and test an emergency light, and your page on emergency lighting indicates, that if it is not possible for decor reasons, or as we already have a single trip switch on a panel that only switches the light in question,and is a locked cupboard, your page suggests I don't need key switches, the electrcian says if we don't have the key switch we won't conform to BS 5266. With a key switch on the other hand you are only cutting the power to your emergency lights without affecting your normal lighting.Emergency lighting key switches, also known as secret key switches, are designed to allow the testing of emergency lighting easily whilst ensuring non-authorised personnel cannot tamper with the light switch. Absolutely Ian, you cannot usually give definitive answers, only be general, because there is so many different situations you have to consider. With such an important role to play in keeping people safe it is vital that this lighting is regularly checked and maintained in accordance with British Standard guidelines. First and foremost, your emergency lighting must be tested by a competent person due to the important nature of the system in ensuring occupant safety in the event of an emergency.
