Page 7: Introduction
The Apollo Discovery ASD-2 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 dual channel Discovery ASD-2 has provision for two separate point detectors, each monitoring a separate sampling pipe run. - Page 8 Discovery ASD-2 Product Guide Apollo Fire Detectors This page is intentionally left blank. www.apollo-fire.co.uk...

Apollo Fire Detectors Discovery ASD-2 Product Guide Wiring The following wiring connections must be made to the detector housing: 24V DC Power Supply. Refer to Section 3.3 for further information. This wiring enters the detector housing via cable seals and is connected to the appropriate terminals on the main circuit board or display board. -
Page 14: Battery Terminal
Figure 3-2: Ferrite core and battery supply wiring The Discovery ASD-2 unit is designed to run from a 24 VDC supply. The supply should be connected to the two way BATTERY connector on the main circuit board ensuring that the wires are correctly orientated. The minimum recommended wire size is 16 x 0.25 mm (18 AWG), or larger if the supply is further than 5 m (16.4 ft) -

(permanent), or socket unions (removable). Note: The Discovery ASD-2 inlet ports are tapered to allow a push fit of the sampling pipe. The pipes should be cut squarely to ensure a good, airtight seal. Solvent adhesive should not be used for this joint. -
Page 16: Exhaust
Apollo Fire Detectors Exhaust Where the Discovery ASD-2 is located outside the protected area, consideration must be given to returning the exhaust air to the protected environment to balance pressure differences that may exist between the two areas. In the majority of applications, this is not necessary as pressure differences are minimal. -
