Lighting Systems

Transient Protection Design provides power filtering and surge protection for breaker panels feeding all lighting systems, drivers and processors. Transient Protection Design also offers protects for individual circuits feeding outdoor landscape lighting pathways. TPD surge protection protects against harmful transient voltages entering the structure and damaging dimming modules and lighting systems on these pathways. When left unprotected, low voltage control wires between systems are pathways for surge events to enter and leave the system traveling to other equipment. Protect lighting system keypad and communication lines by using the TPD-LIT series on copper pathways entering or leaving the facility and between systems with long runs over 200 feet away. 


Landscape Lighting Pathways

Count individual circuits that leave the building exposing a smart lighting switch or smart lighting module that requires protection. If you have a transformer you may want to protect on the line side of the transformer in order to use one unit to protect lighting system inside the building. If you want to protect the transformer you would then need to protect all pathways coming back into the transformer. The cost of the transformer may not be enough to warrant protecting depending on how many times connections/pathways you have feeding outdoor pathways

Lighting Panel Main Lug

Additional surge protection and power filtering can now be applied at the lighting panel when the lighting panel feeds their own internal breakers. This protection has been applied successfully in commercial lighting systems from many years. This one unit will protect all lighting system components including processors, lights drivers and fixtures from both external surges entering the lighting system including internal surges generated by the light circuits and switches themselves.

Lighting system keypads, programmable links, dimming busses, cresset.

Count keypads, dimming bus, sensors, power supplies and contact closure wire pathways as they enter or leave a building. We also recommend protecting equipment in problems areas or long runs that connect network equipment powered from a separate breaker panel.

Why Surge Protect Lighting & Home Automation Systems?

Electricity is essential to our lifestyle.  So much of what we do at home, work and play depends on it.  When you flip the switch on a Crestron lighting system, you expect the lights to come on.  But, if you have not protected the electronic controls to the Creston lighting system with panel mounted surge suppression, the lights may not come on because the circuit boards in the controls have been damaged by surge or lightning activity.


Everyone knows to protect computers and TV sets with rack mount or plug in strip surge suppression.  But, the hardwired Crestron controls that operate the lighting system in the home have the same type of sensitive circuit boards and chips as found in new computers and HDTVs.   But, unlike a computer or TV, you normally can’t protect the Crestron lighting controls with plug in suppression devices.   However, a strategic transient protection design system will!    By first starting with a power filter model TK-TTLP-1S240-FL panel mount suppressor can easily be installed on the panel feeding the lighting controls.  This same unit will also protect the homeowners investment in the LED lights, home automation system, and all other equipment fed from the protected panel.  The processor should also be protected from surges riding in on the landscape lighting or coming in on remote interface wires.  See an example design diagram protecting a lighting system here.


The power utility company supplies us with power to run light bulbs and motors.  The power utility is not responsible to supply computer grade power to run electronics.  Nor is the power utility responsible for what the equipment inside the building are doing to each other.  Helping the client understand this is beneficial to everyone involved on the job.  The Systems Integrator is dealing with every system in the house, and the house must deal with what mother nature throws at it.  No electrical system is perfect, and your equipment needs protection from lightning damage and internally generated transients that overtime take a toll on electronics.

How to Protect Crestron & Lutron Dimming Modules from Lightning!

Lightning is in the area and you are losing dimming modules in your lighting system.  This usually means there are unprotected 24V, 120V or 240 volt pathways coming into your dimming modules from outside the structure.   If these lightning surges get to the dimming modules they can ultimately spread thruoughout the home damaging lighting and home automation systems on the way to ground.  The fix is easy!  Please see the TPD design drawing for lighting system.


By using the TK-LT120-20A-DIN2 power filter and surge suppressor shown in the picture above, lightning can be suppressed, filtered and diverted safely to ground before it ever gets to the dimming module.   This strategy is over 99% percent effective in protecting individual 24V, 120V and 240V circuits feeding any piece of equipment.  Outdoor pumps, fountainspools controls and gates can all be surge and power filter protected.  At times, being the systems integrator forces you to work with sub systems that you did not install.  It could be the security, the irrigation, the pool equipment or a camera system.  It is essential to understand the potential problem areas and recommend to the end user that just replacing equipment without adding surge suppression is a bad idea.  At minimum protect your equipment but being a trained professional you can advise the end user that those systems need proper protection.


If something fails once and nothing is done to prevent it, chances are it is going to fail again.  To change the status quo and surge protect against the same thing from happening again is in everyone’s best interest.  When the customer is made aware of all the pathways that lightning can enter the facility on, understanding what can be done to prevent certain types of damage will get easier.  Eliminate these problems and it will not take long for the customer to realize that being protected is better than being exposed!
