Detectors

Detectors

The ABV-300/D control unit is used together with smoke detectors in the series S65, S50, S65-OE and S50-OE- GA4.

The control unit provides power for connected smoke detectors and transmits smoke and service alarms.

  • ABV-300/D - Control Unit for Smoke DetectorsFor detectors with or without service alarm
  • For supply voltage 24 V AC/DC or 230 V AC
  • Two relay contacts for alarms
  • Serves both optical and ionising smoke detectors
  • LEDs for operation, smoke alarm and service alarm
  • Compact design for DIN-rail mounting

Function

ABV-300/D is designed with state of the art technology to satisfy all the requirements of a reliable fire protection unit. The control unit continuously monitors that the power supply and current values are normal.

A green LED indicates that the power supply is switched on.

The control unit is connected to the smoke detectors by means of a two-wire loop.

Up to 20 detectors can be connected to the same control unit. An end resistor should be connected to the last detector to end the loop.

SDD-OE is a single tube smoke detector for duct mounting which is intended for smoke detection in ventilation systems. The detector is available with or without service alarm.

  • SDD-OE / Optical single tube smoke detector for duct  mountingSmoke detector of optical principle
  • RFI-protected (radio interferences)
  • Multiple detectors can be connected to one control unit (does not apply to SDD-OE65-RAC)
  • Models with service alarm
  • Compact design. The detector is bayonet mounted to simplify service and maintenance.
  • Temperature range -20...+60°C

SDD-OE is an optical smoke detector for mounting on all duct types. It reacts on visible and invisible smoke particles and can therefore detect fire at an early stage. The aluminium venturi tube is mounted in the duct through a hole, Ø 30 mm. The tube can be shortened to fit all duct sizes. The detector housing has a window giving a clear view of the flow indicator and the alarm LED.

Used to detect smoke in all types of buildings. Constructed to meet the rigorous standards required for smoke detector installations.

  • S50-OE-GA4/S65-OE - Optical Smoke Detector for Ceiling MountingOptical type smoke detector
  • Protection against RFI influence (radio interference)
  • Operates within the temperature range -10...+50°C
  • Compact plastic casing and base with bayonette grip simplifies service and maintenance
  • Multiple detectors can be connected to a single control unit
  • Model S50-OE-GA4 also offers service alarm

S50-OE-GA4 and S65-OE are optical smoke detectors for mounting in all types of premises. They react to visible smoke particles (products of combustion).

The detector consists of a detector head and a base.

Models

The smoke detector is available in two models. The basic model, S65-OE, has all the necessary functions for fire supervision.

The detector S50-OE-GA4 has a service alarm, and is used to alert the need for cleaning and to prevent the risk of false alarms due to a dirty detector.

SDD single tube smoke detector for duct mounting is intended for smoke detection in ventilation systems. The detector is available with or without service alarm and auxiliary fan function.

  • SDD-S50/S65 - Single Tube Smoke Detector for Duct MountingIonisation type smoke detector with a minimum of active material
  • RFI-protected (radio interferences)
  • One control unit can control several detectors (does not apply to SDD-S65-RAC)
  • Also available with service alarm, model SDD-S50
  • Compact design. The detector is bayonet mounted to simplify service and maintenance
  • Working range -20 to + 60°C

SDD-S50/S65 are ionisation smoke detectors intended for mounting on all duct types. They react on visible and invisible smoke particles and can therefore detect fire at an early stage.

The aluminium venturi tube is mounted in the duct through a hole, Ø30 mm. The tube length is 540 mm and can be shortened. It can thereby be adjusted to all duct sizes. The detector housing has a window giving a clear view of the flow indicator and the alarm LED. It also has a testplug for simple injection of test gas.

Used to detect smoke in all kinds of areas. Constructed to meet the high demands of a modern fire installation.

  • S50/S65 - S50/S65 - Ionisation Smoke Detector for Ceiling MountingIonisation smoke detector with a minimum of active material
  • Protected against RFI (Radio Frequency Interference)
  • Multiple detectors can be connected to one control unit
  • Model S50 has service alarm
  • Compact plastic cover. Bayonet socket simplifies service och maintenance
  • Temperature range -20...60°C

S50/S65 is an ionisation smoke detector for mounting in all kinds of rooms. It reacts to visible and invisible smoke particles and can therefore detect fire at an early stage. The detector consists of a detector head and a socket.

Models
The standard model S65 has functions for smoke detection. Model S50 with service alarm also detects when it needs to be cleaned, which can prevent possible false alarms caused by contamination.

Work Principle
The detector uses the two-chamber principle. The outer chamber registers the particle density in the air and the inner chamber compensates for slow changes in the surrounding air. Smoke in the outer chamber affects the balance between the two chambers, which triggers an alarm.
