Overview

The EF-ASD1/2 is a professional air-sampling unit, designed to compliment conventional and analogue addressable system technology, by combining standard field-serviceable smoke detectors with a stand-alone air-sampling solution. Ideal for the protection of difficult to access, environmentally demanding, aesthetic or architecturally restricted areas, the EF-ASD is rugged, easy to install, weatherproof, and requires no special tools or software to configure.

Typical EF-ASD Installation

EF-ASD Typical Application

Operation

Air is drawn from the protected area through one or two perforated 25mm pipes. A powerful fan together with sophisticated air-flow monitoring and control circuitry ensures that transport delays are minimised and air-flow is kept within working limits. System status and flow control is continuously displayed (per channel), with on-board fault relays allowing remote fault monitoring. Power management ensures that operating current is kept to a minimum, allowing superior performance and optimisation of external power supply and standby battery resources.

Point Detector Selection

The following point detectors have been listed for use in the EF-ASD1/2 units and are suitable for installations requiring EN 54-20 listing. The table shows the limits that should not be exceeded if the installation is to conform to requirements.

The following detectors have been independently tested and certified for use in the EF-ASD unit and are suitable for EN 54-20 approved Class C installations.
