The Intelligent Base Sounder is for use with Discovery or XP95 ranges. It is a loop-powered sounder used to signal a fire alarm in enclosed areas. A Discovery or XP95 Mounting Base must be fitted to the Base Sounder.

The Ancillary Base Sounder is a local-area sounder designed for indoor use. It can be connected only to detection systems using Discovery or XP95 detectors and control panels with appropriate software.

The 100dB (A) Loop-Powered Sounder is designed  for use in open areas and can be connected to any Discovery or XP95 system.

The Loop-Powered Beacon is a local-area beacon designed for indoor use. The beacon has been developed as a supplement to sounders for use in situations where there is a risk that sounders will not be heard.

The XP95 optical detector uses an internal pulsing LED and a photo-diode at an obtuse angle. In the event of smoke entering the chamber, the light pulse from the LED will be scattered and registered by the photo-diode. A signal is generated and transmitted digitally to the control equipment.

The Series 65 Standard Base has been designed to enable detectors to be fitted without the need of force - particularly useful when fitting to suspended ceilings.
All Series 65 bases have a 'one way only' fit. They can be locked into place by a grub screw using a 1.5mm hexagonal screwdrive.

The heat detector operates by using a matched pair of thermistors to sense heat. One thermistor is exposed to the ambient temperature, the other is sealed. In normal conditions, the two thermistors register similar temperatures, but, on the development of a fire, the temperature recorded by the exposed thermistor will increase rapidly, resulting in an imbalance of the thermistors and causing the detector to change to the alarm state.

The Series 65 Standard Relay Base provides one set of volt-free changeover (from C) contacts that change state when the detector signals an alarm.

The XP95 optical detector uses an internal pulsing LED and a photo-diode at an obtuse angle. In the event of smoke entering the chamber, the light pulse from the LED will be scattered and registered by the photo-diode. A signal is generated and transmitted digitally to the control equipment.

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
