Rubezh IP 212-187 optical-electronic smoke detector — a threshold device for early detection of smoke in premises, connected via a two-wire loop to a control panel. An optical indicator on the housing allows visual monitoring of the detector's status during facility rounds without accessing the central panel. High sensitivity to low smoke concentration ensures a response at the early stage of a fire, when evacuation is still safe.

Advantages

Connection via a two-wire loop: power and signal over a single pair of wires, saving cable
Optical indicator: visual checking of the sensor status during rounds without accessing the console
Early detection: sensitivity to low smoke concentration triggers even before active burning
Optical-electronic principle: stable operation with a low level of false alarms
Simple wiring: a two-wire loop reduces cable and installation costs
Wide applicability: compatible with most domestic control panels

Applications

Office buildings and business centers: basic fire protection via a two-wire loop
Retail premises and stores: an economical smoke detection system with simple installation
Production workshops: monitoring fire-hazardous areas with minimal cable infrastructure costs
Warehouse complexes: equipping a large number of zones on a limited budget

Frequently asked questions

How does a two-wire loop differ from a four-wire one?

In a two-wire loop, power and signal are transmitted over a single pair of wires, which simplifies installation and reduces cable consumption compared to a four-wire scheme.

How can the detector's operability be checked on site?

The optical indicator changes its blinking mode when transitioning to the alarm state; a specialized smoke tester is also used during scheduled maintenance.

Does the IP 212-187 have protection against insects and dust?

The design of the optical chamber provides protection against insects entering; nevertheless, in dusty rooms more frequent maintenance is recommended.
