A high school campus in an Atlanta suburb underwent a complete remodel. Temporary modular buildings were set up on a large area of the campus to act as classrooms during the year-plus long construction.
Due to the temporary structures, accessible HVAC units and threat of vandalism, a stable and reliable solution was needed that would also be easy to both install and move if necessary.
Wireless passive infrared detectors
An integrator was selected who then teamed up with Optex to create a reliable, effective security solution that included iSeries battery-powered, wireless passive infrared detectors. This allowed for a simple, inexpensive yet effective way to protect the assets inside the structures, as well as the HVAC units on the exterior.
The detectors protecting the perimeters of the site were set up to trigger strobe lights that alert an on-site guard to the location of any breach, while the system as a whole is monitored by the district's security team. Because the integrator chose to install a battery-powered, wireless option, any of the units can also be relocated if needed, based on changing site conditions or future security needs.
Crime prevention at perimeter
The temporary campus now maintains a secure perimeter and campus that detects intruders and prevents theft and vandalism. With the battery-powered system in place, the end user has multiple levels of protection and can respond quickly to alarms before any damage is done.
Benefits and features of the iSeries battery-powered, wireless outdoor PIR detectors from OPTEX include:
- No trenching or wiring required allows for a quicker and less expensive install.
- End user will experience less downtime to business operations.
- iSeries version includes Inovonics EN1941 transmitter and batteries pre-installed, allowing for a quicker set-up time on job site.
- Dual PIR feature greatly increase stability outdoor and drastically reduces any false or missed alarms.
- Units can be easily relocated based on changing site conditions.
Outdoor multiple detection pattern
Optex’s outdoor PIR detectors (excluding the LX series) utilise the Multiple Detection Pattern technology, where two double-layered detection patterns (upper and lower) have to be activated to generate an alarm condition. This reduces false alarms, particularly those caused by temperature changes, light reflection and small animals.
The size judging function virtually eliminates false alarms due to small animals and other moving objects such as vehicles.
By utilizing originally developed pyro-elements, it creates a configuration area consisting of 94 high density detection zones. Also, the detection pattern technology requires both detection areas have to be activated in order to generate an alarm condition making it more tolerant to false alarms caused by small animals or pets.
