It's even simpler than my first one. Click on which tone you would like to activate. Click on the pull station to activate it.
This is a Flexzion Quick Alert. It is a Chinese fire alarm. It closely resembles a System Sensor SpectrAlert P241575. It has a very dim strobe light and only has three tones. Tone I sounds like a hi-lo. Tone II sounds like wail. Tone III sounds like siren.
