Smoke Detectors

D Tecta Fire Technology Ltd supplies an extensive range of smoke detectors, including optical, multi-sensor and wireless smoke detectors, from leading manufacturers.

Ionisation smoke detectors

Ionisation smoke detectors have a high sensitivity to flaming, fast burning, fires with possibly small smoke particles. These are particularly suitable for installation in locations such as printing workshops, paper mills and paint stores but are also excellent general-purpose smoke detectors.

 

Optical smoke detectors

Optical smoke detectors are good at detecting slow burning, smouldering fires producing larger smoke particles. These are particularly suited to bedrooms, escape corridors and electrical switch rooms and also for general purpose.

Heat Detectors

D Tecta Fire Technology Ltd supplies both conventional and analogue addressable heat detectors. There are two main types of heat detectors - rate-of-rise detectors and fixed temperature or static heat detectors.

Beam Detectors

D Tecta Fire Technology Ltd supplies  optical beam smoke detector devices that use a projected beam of light to detect smoke across large areas, typically as an indicator of fire.

End-to-end

An end-to-end optical beam smoke detector is a system that has a separate light transmitter and receiver. They are used in applications where there is little available room to install a wide area detector – as the receiver is on a separate element each individual unit is quite small.[10] The small size of the detector is also an advantage for aesthetic installations, where fire protection is required without introducing unsightly or overtly modern devices. Aesthetic considerations are especially important for cultural and heritage sites.[11] End-to-end detectors include the Open-Area Smoke Imaging Detection, which two wavelengths of light to detect smoke because UV & IR wavelengths of light react differently to smoke. The comparative difference helps to verify real smoke by comparing the reflections and seeing a difference in the profile. UV & IR both respond identically to things like blockage (ladder in front to detector path), bugs (blocking beam), fog, steam, and other things that commonly cause false alarms, so the two wavelengths of light to detect smoke accurately.

 

Reflective

A reflective optical beam smoke detector incorporates a light transmitter and the detector on the same unit. The light path is created by reflecting light emitted from the transmitter off a retroreflector that is placed opposite the detector.

 

Motorised

A motorised optical beam smoke detector automatically aligns itself during installation and can compensate for alignment 'drift' i.e. where the optical path of the light beam changes over time Both end-to-end systems and reflective systems can be motorised.

Manual Call Points

Used to allow building occupants to signal that a fire or other emergency exists within the building. They are usually connected to a central fire alarm panel which is in turn connected to an alarm system in the building, and often to a local fire brigade dispatcher as well.

 

Manual Call Point

Manual call point is used to initiate an alarm signal. It can be manual alarm system or part of automatic alarm system. Under normal conditions push button will be in the depressed condition. In the case of fire when the glass cover is broken, the push button will be released by the spring action and will actuate an alarm at the control panel through its switching contacts. In addition to this, there will be an LED indicator on the monitor module for visual indication to locate the call point easily. Previously, the old British standard did not allow hinged covers and plastic resettable elements. Plastic elements must have the same printing as the EN 54 glass.

Sounders

The function of the sounder, in a fire alarm detection system, is to alert persons at risk when a fire is detected and signal the need for evacuation from the premises.

 

Strobe Sounders

Strobe Sounders or Sounder Beacons are used in a fire alarm detection system as notification appliances where it is possible that sounders alone would not be sufficient. The strobe sounder consists of an audible sounder combined with a flashing light. This functions to alert persons at risk when a fire is detected and signal the need for evacuation from the premises.

 

Interface Units

Interface units for fire alarm detection systems provide for simple and effective system connectivity without the need for custom-designed equipment.

 

Interface supply & service

We supply an extensive range of interface units from leading manufacturers including:

 

- Mini Switch Monitors

- Mini Monitor Modules

- Switch Monitors

- Zone Monitors

- Sounder Control Units

- Input/ Output Units

- Output Units

- Sounder Controllers

- Dual Isolators

- Main Switching Input/Output Units

 

Some types of interface units are available in DIN-Rail enclosure or miniature enclosure format as well as standard enclosure.

Emergency Lighting

An emergency light is a battery-backed lighting device that comes on automatically when a building experiences a power outage. Emergency lights are standard in new commercial and high occupancy residential buildings, such as college dormitories. Most building codes require that they be installed in older buildings as well.

The HALO 3 WATT is a discreet and flexible fitting which is specifically designed to

meet the needs of consultants, contractors and end-users.

Purpose designed for interior use, the HALO 3 WATT luminaire is designed to fit into

a hole of 38mm, and comes in two parts, giving the installer more flexibility and ease

of installation.

Designed for indoor installation in a range of public locations the HALO 3 WATT

is an ideal cost effective solution where the emphasis is on discrete and aesthetic

appearance.

Incorporating the latest LED technology, the HALO 3 WATT offers the client long

term cost savings with respect to operational and maintenance costs.

The non-maintained power LED is discretely incorporated into the aluminium spun

lamp head which also acts as the heat sink in order to maximise the lumen output

in emergency.
