Hey Emma, great choice with the Wheelock E90H-W! For a smooth installation, make sure to mount it at the recommended height for optimal coverage. Check the wiring to ensure it complies with your system and local regulations. Remember, secure connections are key. If it’s replacing an existing device, power down the system before swapping. Lastly, run a system test after installation to verify proper functionality. If you run into any specific issues during the process, feel free to ask for assistance. Good luck!
