Discovery Open-Area Voice Sounders comprise a sounder and a sounder visual indicator that have been designed to provide clear instructional messages through the Discovery protocol. They are loop powered wall mounted devices.
Brand InformationDiscovery® 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 offalse 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.
ApplicationThe Discovery Open-Area Voice Sounders are used to provide audible and visual warning of a fire condition and are controlled by the fire control panel by means of the Discovery protocol. This particular feature is only available when 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.
The Discovery Open-Area Voice Sounders offer a choice of 15 evacuation tone/messages pairs available in each device. One of these tone/messages is selected during commissioning in order to suit local regulations or customs. A fire alarm test message is also available.
Whichever evacuation tone/message is selected there is a secondary tone/message which may be used for alerting or warning of a possible evacuation.
CommunicationDiscovery, XP95 & CoreProtocol compatible
