FAS-420-TT2, Aspirating Smoke Detector(2 Detector)

The FAS‐420 Series Aspirating Smoke Detectors are specially designed for direct connection to the Local SecurityNetwork LSN improved version with the extended features. They are active fire detection systems for early fire detection in area and equipment monitoring, as well as for the monitoring of air conditioning units or ducts.

They have the latest detection technology. Their resistance to contamination, the temperature compensation of the sensor signals and initialization in relation to air pressure ensure reliable operation even under extreme environmental conditions.

The SL-versions with extremely quiet fan are applicable for noise sensitive areas, for example hotel rooms, hospitals and bureaus. The noise was reduced to 38 dB(A) and up to 34 dB(A) with additional sound absorber.

Main Features

• Connectable to the fire panels FPA‐5000 and FPA‐1200 with the improved LSN technology
• High deceptive alarm immunity with intelligent signal processing LOGIC·SENS
• Innovative airflow monitoring including single-hole monitoring detects obstruction and breakage
• Initial set-up made easy by automatic initialization
• Easy diagnostics through flash code on the Detector Module or by using the FAS‐ASD‐DIAG diagnostic software

4. Detector Module incl. airflow sensor
5. Aspiration unit
6. Air outlet

The aspiration unit takes air samples from the monitoring area through a pipe system with defined air sampling openings and passes the samples to the Detector Module.

Depending on the response sensitivity of the used Detector Module, the Aspirating Smoke Detector triggers an alarm when the appropriate smoke density is reached. This alarm is displayed via the alarm LED on the unit and is transmitted to the fire panel.

An airflow sensor checks the connected pipe system for breakage and obstruction.

Intelligent signal processing LOGIC·SENS compares the measured smoke level with known disturbance variables and decides between alarm and deception. For the display and transmission of alarm and faults various delay times can be selected.

Each Detector Module is monitored for contamination, signal malfunction and device removal. Malfunctions and certain device states are displayed using various LED flash codes on the Detector Module's electronics PCB.

A fault message is reset via the connected fire panel. Via the Local SecurityNetwork LSN the alarm and fault messages on the unit are reset simultaneously with the detector line.
