Discovery is a range of high specification analogue addressable fire detector suitable for use in commercial, industrial, financial, government, IT/telecoms and healthcare applications. The Discovery range is designed to meet specifications for detectors incorporated in sophisticated systems, Discovery provides engineers with an additional dimension in fire protection capability. The Discovery communications protocol is a development of the proven XP95 protocol, making both ranges of detector compatible.

Disovery Optical Smoke Detector

The Discovery Optical Smoke Detector operates using the light scatter principle and is ideal for applications where slow-burning or smouldering fires pose a potential risk.

Discovery Multisensor Detector

The Discovery Multisensor Detector comprises optical smoke and thermistor temperature sensors which give both a combined signal as well as a separate heat signal for improved false alarm management.

Discovery Heat Detector

Discovery heat detectors have a common profile with ionisation and optical smoke detectors but have a low air flow resistance case made of self-extinguishing white polycarbonate. For the European standard version of the detector, the five modes correspond to five “classes” as defined in EN 54-5. The classes in this standard correspond with different response behaviour, each of which is designed to be suitable for a range of application temperatures. All modes incorporate “fixed temperature” response, which is defined in the standard by the “static response temperature”

Discovery Carbon Monoxide Detector

Discovery CO fire detectors contain a long-life electro-chemical carbon monoxide sensor which is tolerant of low levels of common vapours and household products. The sensing technology is fast, accurate and needs only very low power. The detection capabilities are enhanced by a rate-sensitive response. Fast rises in the carbon monoxide level are often associated with hot fires and the detector will respond earlier under these conditions. The analogue reply from the detector is rate limited to remove nuisance alarms resulting from short-term high levels caused by sources such as pipe smokers or gas flame ignition.

Discovery CO / Heat Multisensor Detector

The Discovery CO/Heat Multisensor Detector contains a CO detection cell and a thermistor temperature sensor whose outputs are combined to give the final analogue value. The way in which the signals from the two sensors are combined depends on the response mode selected. The CO/Heat Multisensor detects the presence of carbon monoxide or heat or a combination of both. The Multisensor construction is similar to that of a CO detector but uses a different lid in order to expose the thermistor to the surrounding air. The signals from the CO sensing cell and the thermistor are independent and represent the amount of CO or the temperature present in the vicinity of the detector. When the detector is used in heat only mode (Mode 5) it operates as an A1R rate-of-rise heat detector with a static threshold of 58°C.

Disovery ASD-1 Aspirating Smoke Detector

The Discovery Aspirating Smoke Detector (ASD) is a point based professional air-sampling unit, designed to complement analogue addressable system technology. It combines standard field serviceable smoke detectors with a stand-alone air sampling solution to provide protection of difficult to access, environmentally demanding, aesthetic or architecturally restricted areas.

Discovery Sounder + Visual Indicator Base

The Discovery Sounder Visual Indicator Base uses the Discovery Protocol and is appropriate for use with the entire Discovery detector head range. For ease of commissioning, a ‘Magnetic Wand’ can be used to test and adjust each sounder locally.

Discovery Sounder VAD Base with Isolator 

The Discovery Sounder VAD Base makes full use of the Discovery protocol. For ease of commissioning, a ‘Magnetic Wand’ can be used to test and adjust each sounder VAD locally.

Discovery Open Area Sounder + Visual

The Discovery Open-Area Sounder Visual Indicator makes full use of the Discovery protocol and has been designed for use in indoor and open areas. When the fire system is being commissioned a 'Magnetic Wand' can be used to adjust and test each sounder locally

Discovery Open Area Voice Sounder

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.

Intellegent Manual Call Point

The Intelligent Manual Call Point has been designed to operate on a loop of intelligent fire detection devices. An alarm is initiated by pressing the resettable element. The manual call point signals to the Control and Indicating Equipment using an interrupt feature within the Apollo Digital Protocol. An alarm status is indicated through the rotation of the resettable element, displaying yellow and black indication bars and a solid red LED. The manual call point can be easily reset from the front using the supplied reset key.


Intellegent Manual Call Point 

The Intelligent Manual Call Point has been designed for indoor applications and are available in a variety of colours for different applications such as initiating a hazard rather than a fire alarm. The Intelligent Manual Call Point can be used on XP95, Discovery and CoreProtocol systems.


Intellegent Manual Call Point

A seven-segment DIL switch enables addressing of each call point at commissioning stage. When operated, the manual call point interrupts the polling cycle for a fast response. Bi-coloured LEDs indicate isolate and normal conditions.

Discovery Intellegent Twin Switch Monitor

The Intelligent Twin Switch Monitor provides the function of two Switch Monitor units within one enclosure. The two units are electrically independent of each other. There is a DIL switch on each unit to set the address. Both Switch Monitor units in the enclosure are designed to monitor the state of one or more single pole, volt-free contacts connected on a single pair of cables to report the status. It has a selectable status reporting delay making it suitable for monitoring flow switches.
