Discovery® is a range of high-specification, analogue addressable fire detectors and alarm devices. Discovery detectors offer effective false alarm management by a combination of EN 54 approved operating modes and sophisticated algorithms. Drift compensation further reduces the likelihood of false alarms caused by a build-up of dust in the sensing chamber. In addition to the familiar smoke and heat detectors, the Discovery range features two multisensor detectors. One is an optical/heat multisensor which can be used to protect against many types of fire risk. The other is a carbon monoxide/heat multisensor which protects against both smouldering fires and those generating heat.

Application

The Discovery Open-Area Sounder Visual Indicator is used to provide audible and visual warning of fire and is controlled by the fire control panel by means of the Discovery or CoreProtocol. The particular features of this sounder Visual Indicator are available when it is being controlled by the full Discovery or CoreProtocol with the fire control panel programmed accordingly. Information on available features should be requested from the panel manufacturer. These are identical to the Discovery Sounder Visual Indicator Base but the Open-Area Sounder Visual Indicator is a wall-mounted stand-alone device that produces a higher sound output of up to 100dB(A).

Communication

Discovery, XP95 & CoreProtocol compatible

Maintenance & Service

Detectors should be maintained according to BS 5839-1 or other locally applicable code. Test equipment can be ordered from Apollo for testing smoke and heat detectors. Detectors should not be cleaned in the field except for careful removal of exterior dirt with a damp cloth. For cleaning and recalibration detectors should be returned to Apollo Fire Detectors or to the local distributor.
