How do i program a keychain and the smoke dector

to program any new sensors first you must access the installer menu by opening the front cover and using the red buttons typing in the installers code,(4321) is the default code. once that is done press the add button, then the sensor/remote button, then trip sensor(keyfob by pressing both the lock and unlock buttons together until the system beeps) or (removing the smoke detector from the base until it beeps). Once the sensor has been learned it will say keychain remote, press the sensor/remote button repeatedly until it says the correct location, then press done. then enter group code 01 for the keyfob and 26 for the smoke detector. then done.
