Introduction
The Apollo Discovery ASD-1 is an aspirating smoke detection system that utilizes an air-sampling pipe
network to draw air towards conventional or analog addressable point detectors in an aspirated enclosure.
The single channel Discovery ASD-1 system has provision for one or two point detectors allowing for single,
failsafe redundancy or mixed detection strategies.
Point detectors are wired directly into the signalling circuit connected to the monitoring fire alarm control panel.
Any alarms or faults derived from the analog or conventional point detector will be reported directly to
monitoring fire panel through the signalling circuit for that detector.
The Discovery ASD-1 system provides airflow monitoring circuitry and an aspiration system that is
configurable. The airflow level is displayed on a ten element bar graph with adjustments for flow sensitivity
and high/low flow thresholds. Flow failure is reported to the central panel via an internal mini switch module.
Important Note:
Aspirating Smoke Detectors supplied and installed within the EU from July 2011 must
conform to the Construction Products Regulation (EU) 305/2011 (CPR) and the related European
Standard EN 54-20.
This unit has been tested and certified to ensure general conformance to the above directive and
standard but strict adherence to this Product Guide is required to ensure that the installation meets
these requirements in all respects.
