ASD-5

Product description

A smoke alarm designed for timely warning of fire and smoke with autonomous power supply (battery life under normal conditions is more than 10 years).

  • Compliance with all requirements of EN 14604: 2005 and the increased requirements of the German directive VdS3131, in particular:
  • The service life of one set of batteries is 5 years
  • Implementation of intelligent sensitivity calibration using a built-in microcontroller
  • Built-in drift compensation mechanism (including due to pollution in the smoke chamber). This mechanism automatically adjusts the sensitivity of the alarm to the factory level during operation
  • Sound indication of exceeding the limit level of the compensation threshold (signal to clean the smoke chamber from dust)
  • Smooth increase in sound in "Alarm" or "Test" modes
  • "Hush" function - muting the "Alarm" signal for 10 minutes. by briefly pressing the "Test" button

Topic 1. Components of fire protection systems

Section 10.4. Smoke alarms (ASD-5, ASD-10QR, remote control ASD-RRC).
In section 10.4 of informational materials "Components of fire protection systems" smoke alarms ASD-5 with replaceable batteries for 5 years of continuous operation are considered. Innovative design solutions used in this product are presented. Information is provided on the use of ASD-5 as a U-PROX SMOKE radio channel product from another U-Prox manufacturer. Radio channel smoke alarms ASD-10QR are also considered, which meet all the requirements of EN14604: 2005 and VdS3131 and VdS3515 directives. The ASD-RRC remote control for these alarms and utility model patents implemented in the ASD-10QR are presented.
