- The range

Discovery is a range of high specification analogue addressable fire detectors. 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.

Ionisation Smoke Detector

Air in the dual sensing chambers is irradiated to produce ions that travel to the positive and negative electrodes, creating a current flow. As smoke enters the outer chamber, the flow drops and voltage increases. The voltage is measured and an analogue signal is converted to digital for transmission to the control equipment.

Optical Smoke Detector

The Discovery optical smoke detector uses an IR LED which pulses light across a smoke chamber with a photo-diode set an obtuse angle. In clear air it receives no light, but when smoke enters the chamber, light from the LED is scattered onto the photo-diode. A signal is then processed to provide an analogue value for transmission when the detector is polled.

Heat Detector

The Discovery heat detector, distinguishable by the low airflow resistant case, uses a single thermistor to sense the air temperature around the detector. The thermistor is connected in a resistor network, which produces a voltage output dependent on temperature.

Discovery Sounder Beacon Base

The Discovery Sounder Beacon Base makes full use of the Discovery protocol. When the fire system is being commissioned a magnetic wand can be used to adjust and test each sounder locally.
More information ...

Multisensor Detector

The Discovery multisensor detector contains an optical smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analogue value. The multisensor is, therefore, useful over a wide range of applications and is highly immune to false alarm sources.

Carbon Monoxide Detector

The Discovery Carbon Monoxide (CO) fire detector contains a long-life electrochemical CO sensor. The sensing technology is fast, accurate and needs only very low power. CO detectors do not detect smoke particles or heat and are not universal replacements for smoke detectors.
More information ...

MiniDisc Remote Indicator

The MiniDisc Remote Indicator is a light-weight, compact indicator for use in fire protection systems.

Intelligent Mounting Base

All detectors in the Discovery and XP95 range fit into the Intelligent Mounting Base. The Mounting Base is a low insertion force base with stainless steel contacts for the detector terminals. XPERT cards are supplied with all bases.
More information ...

Intelligent Deep Base

The Intelligent Deep Base is a mounting base for Discovery and XP95 products which has an increased depth which allows for cables to be inserted into the side of the product.
More information ...

Intelligent Low Power Relay Base

The Intelligent Low Power Relay Base incorporates a low power relay to control field equipment such as automatic door closers.
More information ...

NEW! Isolating Base

The new Isolating Base senses and detects short-circuit faults on Discovery and XP95 loops and spurs.
More information ...

Intelligent Heater Base

The Intelligent Heater Base is designed to be used in cold climates where environmental conditions could result in either icing or condensation affecting the operation of detectors.
More information ...

Intelligent Isolator

The Intelligent Isolator is placed at intervals on the loop and ensures that, in the case of a short circuit, only the section between the isolators will be affected.
More information ...

Intelligent Isolator Base

The Intelligent Isolator Base is unique and designed only to accept the Intelligent Isolator.

Isolating Base

The Isolating Base senses and detects short-circuit faults on Discovery and XP95 loops and spurs.

Discovery Manual Call Point

The Discovery Manual Call Point is compliant with EN54-11. The Call Point can be addressed at the commissioning stage by means of a seven-segment DIL switch. When operated, the manual call point interrupts the polling cycle for a fast response.
More information ...

Waterproof Manual Call Point

The Waterproof Manual Call Point has been designed for use outdoors and in places where moisture can occur. It is compliant with EN54-11 and can be used with the Discovery range.
