Jablotron JA-111ST-A BUS smoke and heat detector with sound and siren

JA-111ST-A detects fire hazard indoors. It can be used both for residential and commercial purposes. In addition, it is possible to install it in caravans, motorhomes and caravans. However, it is not applicable in industrial environments. The detector is made to also be able to activate other JA-151ST-A or JA-111ST-A detectors in the installation, and then it also acts as a siren for the alarm. It can also operate independently, in case of lost connection, as long as it is equipped with backup batteries. The unit can be set to detect smoke AND heat, smoke OR heat, ONLY smoke or ONLY heat. This is possible because it consists of two individual detectors. A heat detector and an optical smoke detector - which detect a change in light reflection in its built-in smoke chamber. It also has a built-in light sensor that can be used for test signal. The unit sends both a signal to the alarm center and warns locally.

Note that the detector takes up one space in the system.
