JA-151ST-A Wireless combined smoke and heat detector with built-in siren

Used to detect a fire risk in the interior of residential or commercial buildings. It comprises a siren that indicates a fire alarm both from the entire detector and from another fire detector in the system.

Wireless combined smoke and heat detector with built-in siren

JA-151ST-A Wireless combined smoke and heat detector with built-in siren

The detector communicates wirelessly and it is supplied by batteries (3x 1.5 V AA).

If the detector is operated without being assigned to a control panel or if communication with the control panel has been lost, it works in an autonomous mode (EN 14604).

The detector indicates a dangerous situation optically with an integrated light and a siren. It is able to acoustically report:

  • a fire alarm detected by the detector itself
  • a fire alarm from the system (alarm triggered by another fire detector)
  • another type of alarm (e.g. an intruder alarm)
  • for alarms reported by the system, sections can be set for which the alarm will be indicated

The product contains two separate detectors – an optical smoke detector and a temperature detector. The optical smoke detector uses the diffused light principle. It is very sensitive to particles that are present in thick smoke. It is less sensitive to small particles produced by the burning of liquids such as e.g. alcohol. Therefore, a heat detector is integrated, which responds better to a fire developing heat quickly with a small amount of smoke.

The fire detectors should be installed by a trained installer with a valid Jablotron certificate. The detector is not designed for installation in industrial environments.
