OPTEX Battery-Powered, Wireless Protection at Electrical Substation



Multiple electrical substations in the Mid-West United States operated by a large electric power holding company.




Due to the high price of copper, the customer faced the growing issue of theft and damage at multiple sites. The few hundred dollars of copper that was being ripped out was causing hundreds of thousands of dollars in damage, repairs, and down time, while creating unsafe grounding conditions for the electrical equipment. Changing site conditions, large perimeters and the inability to trench, and remote locations were all challenges that needed to be addressed when deciding on a solution. 




An integrator was selected who then teamed up with Optex to create a reliable, effective security solution. The team decided on protecting multiple areas on the properties by taking a layered security approach. The solution would meet the customer's needs by protecting the sites from copper theft, while also eliminating the chance and liability of injury or death from trespassers. 

At the first area of intrusion, both the existing perimeter fence and automatic gate systems were reinforced using pairs of the SL-350QFRi, a battery-powered, wireless 350ft. point-to-point photoelectric detector. The battery-powered perimeter beam system allowed the integrator to set up the units without running power to them, eliminating the need to trench or run cables. 

For the interior locations on the property, mid-range SIP series and short range HX series passive infrared detectors were installed to offer the customer a stable back up to the perimeter system. 

Because the customer operated their own central monitoring station, all detectors on the property were set up to trigger PTZ cameras that were fixed within the sensor's area of detection. This allowed the monitoring station to capture and record any intrusions on the property and take the necessary action before any theft or vandalism occurred.




The end user now maintains a secure perimeter and site that detects intruders and helps to prevent possible injury. With the system in place, the customer has multiple levels of protection and can respond with quick efficiency to catch criminal activity.

Optex expands on its industry leading outdoor, battery-powered iSeries intrusion line by adding the SL-350QFR and iSeries SL-350QFRi, a 350 ft. battery-powered photoelectric detector requiring no trenching or wiring. “Even with the success of our 100 ft. and 200 ft. battery-powered beams, there were still larger applications where too many beams sets would be required. With the SL-350QFRi, we will be able to not only offer a more cost-effective solution for these larger sites, but also offer additional features that our customers asked for, such as quad beam detection and extended battery life of up to 10 years,” says Scott Simmons, Vice President of Sales.

The iSeries SL-350QFRi version includes an Inovonics wireless EN1941 transmitter pre-installed, while the SL-350QFR is compatible with most manufacturers wireless systems and allows the user suppy their own. Both versions come with four batteries per set, with the option of expanding to eight for up to 10 years of battery life.

In addition, the SL-350QFRi is compatible with the AX-TW200 line of beam towers for a clean, concealed, wireless mounting option. “Our sales staff and technical team will work closely with the integrator and installer to find the best mounting option and layout on their job site. When a site plan is provided, we’ll custom build the towers and pre-install the SL-350QFR series beams in them based on the job site specifications, all at no charge,” states Frank Chavez, Lead Technician. “We'll even ship them directly to the job site, labeled for position and ready to be installed.” 


Benefits and features of the 350ft. SL-350QFR and iSeries SL-350QFRi battery-powered Photoelectric Detectors Include:

  • No trenching or wiring required allows for a quicker and less expensive install. End user will experience less downtime to business operations.
  • iSeries SL-350QFRi version includes Inovonics transmitter pre-installed allowing for a quicker set-up time on job site. 
  • New long distance viewfinder adds to ease of installation and insures optimal beam performance by increasing visibility during the alignment process.
  • Four Selectable beam frequencies for stacking applications when a higher level of security is required

The flexibility and durability of the SL-350QFR series make it well suited for substations, oil and gas facilities, transportation, correctional facilities, storage and impound yards, critical infrastructures, industrial complexes and solar fields.
