The requirement of a UL certification generally relates to egress. Since Kisi does not typically control egress in relation to your access control system, UL certification is not necessary for the parts Kisi manufactures. However, Kisi is typically used with UL listed parts such as power supplies or locks.
Motion sensors and/or request to exit buttons are typically wired in-series with the lock, thus bypassing the Kisi system when people exit a building that utilizes fail-safe locks. For those buildings using fail-secure locks, egress is accomplished by using either the door handle or a push bar. If you have motion sensors or push to exit buttons, your installer can provide the UL certification for the device(s) installed.
If you do have Kisi set up to control egress, the UL listing for power to the Kisi controller can be found here.
The Kisi reader's UL certification for power can be found on your switch's datasheets, if you are using your own Power over Ethernet (PoE) enabled switch. If you are using a Kisi provided PoE injector, there is no UL certification, however, you can find RoHs certification here.
If you need UL certification for the PoE injector connected to the Kisi reader, Kisi recommends this model.
If your installation requires UL certification from the Kisi side, Kisi offers the Altronix power supply which is UL certified.
