The Shater series electrooptical smoke detector with advanced characteristics and aesthetic appearance has the following features:

  • Unique self-design microcircuit ASIC R2 developed by RUBEZH company is used in the detector for optoelectronic coupler signals digital processing. Schematic approach is realized in this microcircuit, which results in no pickup due to close position of ungrounded electrical appliances, light sources, wires. As a result, false alarm possibility due to electromagnetic disturbance (this approach was specially selected to exclude daylight lamp induced disturbance), is absolutely excluded;
  • two-color LED at the face of the housing for unambiguous detector state indication;
  • protective screen at smoke chamber;
  • enlarged smoke stack area ensures timely detector activation when first signs of smoke appear;
  • detector testing is performed using process hole by special tester. This ensures total check of detector functioning including optical channel;
  • detector's housing is made of wear and impact resistant ABS, color may be selected by customer's request;
  • wires screw fastening to the detector's base.

The detector is intended for 24 hours uninterrupted operation with control and indicating panels ensuring supply voltage in the alarm loop within the range of 9 to 30V, which accept Fire signal in the form of detector internal resistance hopping decrease in normal polarity up to the value of 1000 Ohm, such as Granit, Grand Magistr, VERS PK, Signal-20, Signal-20P, etc.


Detector state indication:

  • "Fire" - red LED steady on;
  • Stand-by mode - single greed flash with 5 s frequency.

The Fire signal remains active when smoke exposure to the detector stops. Reset is performed using receiving and control device by detector power switching off at least 2 sec.

Connection of the detector and the base is of plug-type. Circular contacts allow mounting of the detector without orientation with respect to the base. The base is unified, any Rubezh detector may be installed without the need of reinstallation. The AL minus wire is connected to short-circuited by the 3 and 4 detector contacts. This provides AL failure signal sending to FACIE when the detector is disconnected.

The detector may be installed on suspended ceiling using special base with mounting ring.

Screw-free mounting method using clamp-button ensures reliable contact and easy installation.

In case of detector connection to receiving and control panel AL with activated detectors quantity determination function (double-trip function), the auxiliary resistor Raux is used. The auxiliary resistor rating depends on receiving and control panel connected and is designed using device circuit loop resistance in Fire and Warning modes as an input data. Instead of auxiliary resistor, US-01 compatibilizer may be used. It is plugged into the detector's base and has a resistor (rating to be determined at ordering) and a terminal block.

The detector may operate with four-wire connection devices. For this purpose, US-02 compatibilizer is used. This compatibilizer shall be mounted within detector's standard base.

The detector provides connection with remote optical alarm device.
