ZP720-3P Addressable Heat Detector – Polar White

The ZP720-3P addressable thermal detector is a POLAR WHITE, thermistor controlled device that responds to changes in its ambient temperature. The device provides a reliable response to fires in areas where environmental conditions may prohibit the use of smoke detectors. The sensitivity of each detector is set by the ZP control panel and can be adjusted between four levels ranging between 58°C and 75°C – eithermanually or automatically on a timed basis.

At sensitivity level two, the ZP720-3 fully meets the requirements of EN54 Pt 5 (grade 1) and is approved by several international approval bodies. Temperature levels are continuously sensed by the unit and transmitted via the ZP wiring loop as electronic signals, which are assessed and verified by the control panel prior to any alarm decision being taken.

Key Features:

  • Analogue sensing – reduces false and unwanted alarms
  • Addressable – system knows the status and location of every sensor
  • Automatic self test
  • EN54 Part 5 approved and CPD certified


ZP730-2P Optical Smoke Sensor – Polar White

Designed for early response to slow burning, smoldering fires, the ZP730-2P is a POLAR WHITE, addressable smoke detector developed to provide reliable sensing for most fire alarm applications. The detector’s proven stability in air movement associated with air conditioning systems has made it a popular selection for modern building interiors. Operating on light scatter principles, the ZP730-2 fully meets the sensitivity requirements of EN54 Pt 7 and is approved by several international approval bodies.

Key Features:

  • Responds to slow burning fires
  • EN54 Pt7and CPD certified
  • Analogue sensing – reduces false and unwanted alarms
  • Addressable – system knows the status and location of every sensor
  • Alarm verification, self test, auto contamination adjustment

OSID Detector

OSID Open-area Smoke Imaging Detector – OSI-10 Imager 8° FOV

The OSI-10 covers a distance of 30 – 150m with the OSE-SPW. This configuration is for a 1 on 1 system and is not suitable to work with high powered emitters.

The company that revolutionized very early warning smoke detection with VESDA has reinvented smoke detection for open spaces with Open-area Smoke Imaging Detection (OSID). OSID by Xtralis provides reliable, cost-effective smoke detection for open spaces where fire detection presents unique challenges and where very early warning is not always the priority.

In its simplest configuration, OSID by Xtralis uses one imager, a camera-like device with a wide field of view, and a wired or battery-powered emitter roughly aligned on the opposite wall within the protected area. The emitter sends both infrared and ultraviolet coded light signals to the imager. If the light reception is altered due to the presence of genuine smoke particles, the imager will go into alarm. The novel use of dual light frequencies in an open-path device enables OSID to discriminate between real smoke and other objects, including insects, steam, condensation and dust, thus drastically reducing false alarms.

Key Features:

OSID’s uncompromising performance is based on the patented use of digital imaging, dual-frequency beams and smart algorithms delivering:

  • Patented dual wavelength, UV & IR, particle detection
  • CMOS Imager with wide viewing angles
  • Simple installation, commissioning and maintenance
  • High tolerance to vibration and structural movement
  • High tolerance to dust, fogging, steam, reflections and object intrusion
  • High resistance to reflected sunlight
  • On-board log memory
  • Software tool for diagnostic purposes
  • Aesthetically discreet and 3D coverage
  • Long range up to 150 m. (492 ft.) with minimal free space (Ø15 cm./5.85”)


OSID is ideal for use in a wide range of industries and applications. These include atriums, domes and large rooms in:

  • Airports
  • Train stations
  • Shopping centres
  • Stadiums
  • Educational facilities
  • Hotels, convention centres and office buildings/complexes
  • Entertainment venues
  • Warehouses and production floors
