Difference between smoke detector and smoke alarm
A smoke detector is a device that has only in-built sensor to detect the presence of smoke whereas a smoke alarm is a device that comprises of smoke detection sensor, audible sounder, and power supply. The power supply can be a normal battery or electrical mains supply.
A smoke alarm contains a sensor, audible sounder and power supply. It is a single or multiple-station smoke-sensing device. It is a standalone device. It is generally installed in the house.
A smoke detector contains only a sensor. It requires an external sounder and power source to create an alarm. It is generally connected to the fire alarm system.
