Fire Protection Home Security System

Simple and Effective

This eMastiff smoke alarm is simple, with no smart features but is extremely effective in detecting smoke and alerting the people nearby. The only thing it needs is a standard 9V battery which keeps it charged for months. 

Solid ABS Construction

The eMastiff fire alarm is made up of high-quality ABS plastic which means it is durable and has an extremely high melting point. So, you don’t have to worry about it melting in case there is a fire. 

75dB Loud Sound

Never compromise on your and your family’s safety and security. Most alarms fail to alert people on time which leads to unfortunate incidents. This eMastiff alarm has a high sensitivity sensor which is directly linked to the 75dB alarm that goes off instantly and alerts everyone in the vicinity of a potential fire hazard. The sound is loud enough to be heard over 100 meters. 

Simple Setup

The alarm needs a 9V battery which has to be bought separately and two screws which are present in the box. Just place the screws in the wall and lock the sensor firmly and you are good to go.
