MK TEST FISH KEY FOR SECRET EMERGENCY LIGHT SWITCHES

Product Information

I feel this is wrong as another consumer unit (keypad) has been powered by breaking into the test circuit of the EL. Hi All, I've been reading through all these posts, trying to work out how Emergency Exit lights should be wired with Test switches and think I've worked it out from the varying posts here and on other forums.

Bedsit houses of multiple occupation of one to four storeys (with individual cooking facilities within bedsits) require conventional lighting and emergency escape lighting if risk requires such or there is no effective borrowed light. Bedsit houses of multiple occupation of five or six storeys with individual cooking facilities within bedsits require conventional lighting and emergency escape lighting Emergency escape lighting comes on automatically when the mains power fails and gives off sufficient illumination to enable occupants and visitors to evacuate the premises safely. I have to wire some lighting in an office. I am putting 4 6' flo fittings in each office (there request). I was going to make on of them a combined emergency fitting and normal light. The supply will be looped in at the switch, is the correct way to wire it - power in to the fish switch (are they DP?) then via a 1 way switch to the fitting in 3 core taking permanent, switched and neutral. By operating the test switch on the new wiring system you are still simulating a mains failure its just the normal lighting is not extinguishing but the emergency lights are illuminating. The longevity of emergency lights is better if lamps are changed before they are fully failing. However, this recommendation probably only applies if an organisation has a contractor for the maintenance of emergency lighting and the costs of a call-out were to be substantial. In such a case pre-emptive maintenance (changing while the light is still working) makes sense.After all escape lighting is still emergency lighting, just that provided specifically for the purposes of providing sufficient illumination of exit routes to allow safe egress. In my humble opinion the switch should be of "simulation" status IE cutting power (as it would if in a power cut, fire, etc.) and illuminating EL only. Offering exceptional quality and value for money, this switch is constructed from a durable plastic, and is ideal for controlling restricted access lighting or alarms via the provided key. However I'm not too sure whether they are maintained, non-maintained or self contained or if either of them are similar or not. Simple system would be you switch the main lights on as normal, then operate the test key switch which simulates a power cut - so you can visually see the EL works.

Special consideration should be given to homes for the elderly, hospitals, crowded areas such as pubs, discos and supermarkets and to whether or not the premises are residential. Emergency lighting test key switches, also known as secret key switches, are designed to allow the testing of emergency lights easily whilst ensuring non-authorised personnel cannot tamper with the test switch. Escape lighting should not be on it's own circuit unless of the maintained type or part of a central battery system as it should operate on local circuit failure.We have keypad entry systems but a contractor has wired up the power feed to it from the Emergency lighting system - IE: when you do a key test on the EL the keypad loses power and so can't be used to gain entry into the office (this is also the case for 3 other doors into our office).
