Fire Detection Systems - Products
A full range of fire detectors are available as either Conventional (non-addressable) or Addressable devices.
Conventional Smoke Detectors
Conventional Smoke detectors are available as Optical, Ionisation, and Multisensor (combined smoke and heat). Conventional Heat Detectors are supplied as one of four options designated as either a Static or Rate of Rise response. Detector bases are available in a number of options; standard, diode, relay, and integrated sounder bases as examples. The conventional range of detectors also incorporates manual alarm call points in a choice of colours together with an IP67 version for outdoor use.
Addressable Smoke Detectors
Addressable Smoke detectors are available as Optical, Ionisation, CO, and Multisensor (combined smoke and heat or combined CO/heat). All Addressable Detectors, including the Heat detector, can operate in one of five selectable response modes allowing an adjustment of sensitivity (and increased protection from false alarms) to suit the specific fire risk within the protected area.
All Addressable smoke detectors can compensate for sensor drift. Sensor drift describes the change in sensitivity when the sensor element becomes contaminated by, for example, dust within the sensor chamber.
Audible & Visual Warning Devices
Audible and visual warning devices are available for both Conventional and Addressable alarm systems. A number of options exist, for both audible and visual alarms, from traditional alarm bells, to space saving integrated base units, and wide area high output alarm devices for areas with high levels of ambient background noise.
Combined sounder/beacon warning devices are available in either conventional or addressable options and warning beacons can provided in accordance with EN54 - 23 design codes for Visual Alarm Devices (VAD’s).
A full range of devices (detectors and audible/visual alarms), for both Conventional and Addressable technologies, are available with Marine approvals from, amongst others, Lloyds Register, American Bureau of Shipping, DNV, and Bureau Veritas.
Flame detectors are ideally suited to fire detection at distance, with the ability to cover large areas with a small number of devices. Detector models are available that monitor Ultraviolet or Infra-red (or a combination of both) emissions from a flame to provide a fast, effective, fire detector with excellent false alarm immunity.
Detectors have their electronics installed within explosion proof housings making flame detectors suitable for installation and use in Hazardous Areas. Detectors can also be supplied in stainless steel housings for marine or off-shore applications.
Flame detectors typically possess both analogue 4-20mA and relay outputs for alarm and fault signalling. Most detectors will have an in-built, automatic test function for confirmation that the lens “viewing window” is clear from dirt and obstruction and thus confirming the detector is operating correctly.

Linear Heat Detection Cable
Digital Linear Heat Detection Cable is an effective continuous heat detector, operating at a set temperature (the cable works by having an inner insulation sheath that degrades at a set temperature causing the two conductors to short together and act as a switch).
The cable, through its simple operation is suited to both Conventional detection circuits and, via an appropriate interface module, Addressable Loops too. With the use of a suitable Intrinsically Safe barrier or isolator, the cable, being classed as a “simple device” can be used in Hazardous Areas.
With the outer sheath of the cable being resistant to Oils and Chemicals the cable is ideally suited to installation on Petrochemical and Pharmaceutical sites. Alarm temperatures for the cable are typically between 680C - 2400C
Being a static cable, the Linear Heat sensor is effectively maintenance free, routine inspections of the cable may be required to ensure no mechanical damage has occurred otherwise there is no active maintenance required.
