IP 212-87 electrooptical smoke detector is designed for early detection of fire accompanied with low smoke concentration in various buildings and facilities enclosed rooms. Detector power supply and Fire signal transmission is provided via double-wire alarm loop and is accompanied with optical indicator activation at detector tripping. The detector does not respond to temperature, humidity changes and to the presence of flame and natural or artificial light.


The Shater series electrooptical smoke detector with advanced characteristics and aesthetic appearance, visual state indication LEDs, and screw-free contacts has the following design advantages:

  • Unique self-design microcircuit is used in the detector for optoelectronic coupler signals digital processing;
  • new and improved dust compensation algorithm which increases interference resistance and eliminates false alarms;
  • six optical indication modes;
  • enlarged smoke stack area ensures timely detector activation when first signs of smoke appear;
  • detector testing is performed by two ways: using OT-1 optical tester (by sending laser ray to detector's LED) or special tester (introduction of metal rod to smoke chamber of the detector through process hole in the housing). This ensures total check of detector functioning including optical channel;
  • detector's housing is made of impact- and wear-resistant high quality material ABS.

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.


The detector performs the following functions:

  • smoke concentration measurement;
  • digital processing of the measurement results based on special algorithms and making a decision on the Fire signal generation;
  • smoke channel test and functioning indication;
  • stand-by mode and failure indication;
  • dust content in the smoke chamber automatic compensation;
  • testing with special optical tester.

Detector state indications are listed in the Table:

The Fire signal remains active when smoke exposure to the detector stops. Reset is performed using receiving and control panel 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.
