Internal and External Lighting for communal areas

External and Grounds Lighting, -Car Park Lighting

In most cases, the major Developers include the provision of external lighting units.  The lighting units installed can vary from large lamp columns, most seen in access roads in and around the development, or smaller units or bollard lighting, mostly installed within the grounds or communal car park areas.

Dependant on whether or not the Developer has transferred the access roads to the local highways department for adoption, the management company will be responsible for arranging any necessary repairs to be carried out should the street lighting lamp post unit fail. In most cases, when access roads have been 'adopted' by the local highways authority, you will note that there is a number painted on the column. 

Should it be necessary for you contact Merlin Estates Ltd to report a faulty street lamp column, please make a note of the number stencilled on the outside as Merlin Estates Ltd can report this information onto the local highways authority on your behalf.

Should you encounter other problems concerning exterior lighting, for example, damage to car park lighting bollards, or exterior lighting above communal entrance doors to an apartment block, please do not hesitate to contact Merlin Estates Ltd with a description and location of the lighting unit, and we will ensure a contractor is instructed to attend site to address the issue and carry out all necessary repairs accordingly.  

When do the car park lights come on?

Depending on how the developer installed the lighting systems for your development, there are a number of ways this can be controlled.  On most of the newer developments, all external lighting is controlled via a light level sensor located either on top of the individual lamp columns or via a sensor unit located on the exterior elevation of the building.  The sensor measures the level of light, generated by the sun, present.  When the measurement of light falls, the lamp columns will be activated.

On some of the older developments, the external lighting is controlled by a timer clock located within the electricity cupboard in the communal areas of the apartment block. This involves someone attending site twice a year to manually change the timer clock, so as to reflect the new 'lighting up times required. 

Internal Lighting for communal areas

Very similar to the external lighting systems there are similar systems used to control the activation of the internal lighting.  These include the installation of a passive infrared light switch located at the top and bottom of each internal staircase and passageways. These switches are activated by movement.

An alternative control, known as dusk to dawn lighting sensors which are activated via a manually operated timer located within the consumer unit. There is also a conventional time switch which is simply operated manually by a time clock located within the electricity cupboard.  Another system is operated via a pneumatic timer switch, which operates the lights when depressed.  The time span activating the lights can be adjusted if and when required. Finally, in some of the older developments, the internal communal lighting is hard wired to remain on twenty four hours a day.

Although, movement activated light switches are often deemed to be energy saving, in terms of energy consumption,  they are known to have a high failure rate due to wear and tear of the lamp, and may require early replacement of the units.

Emergency lighting

In addition to the above apartment blocks are fitted with emergency light fittings.  These have the appearance of normal regular lighting units, with one exception; they are fitted with a battery backup unit, which are activated when there is power loss to the building and consumer unit.

During a loss of power to the building, the battery within the unit is automatically activated, and will continue providing a lighting source until the battery is drained, or until the power is restored whichever is the quickest.  The emergency lighting units can generally be identified by a small LED which is either green or red.  These emergency lights are visually tested on a monthly basis, and have full battery checks every 6 months to comply with Health and Safety Regulations.
