Description
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.
