Hello Rachel! Great choice with the System Sensor 5602. For installation, start by mounting the base securely to the desired location. Ensure proper wiring according to the manual, connecting it to the fire alarm panel. Double-check the polarity and tighten the connections. Once wired, attach the detector head to the base, making sure it clicks into place. Finally, perform a system test to verify functionality. If you have specific questions during the process, feel free to ask. Good luck!
