Wireless smoke / heat detector – WSD 1

Download Catalog

The wireless fire alarm system make installation much easier than ever. We save 95% installing time because there is no cable anymore. Since then, cost for the system and maintenance is much lower.

FireSmart wireless smoke and heat detectors are compliant to EN 54-25, EN 54-5, EN 54-7 and all relevant parts of EN 54 standard.

SMOKE DETECTORS

The WSD-1 wireless smoke detector is compatible with FireSmart wireless control panel WCP.

The detector utilize an infrared LED light source and silicon photo diode receiving element in the smoke chamber. In a normal standby condition, the receiving element receives no light from the pulsing LED light source. In the event of a fire, smoke enters the detector smoke chamber and light is reflected from the smoke particle to the receiving element.  The light received is converted in to an electronic signal.

Signals are processed and compared to a reference level, and when two consecutive signals exceeding the reference level and received within a specifed period of time, the time delay circuit triggers a switch to activate the alarm signal.

HEAT DETECTORS

The WSD-2 incorporates a highly linear thermistor circuit.  The specially designed cover protects the thermistor while allowing maximum air flow. The thermistor
circuit produces a voltage proportional to the temperature.  This information is transmitted to the control panel as a digital value. When the ambient temperature
exceeds a pre-programmed threshold (fixed temp or rate of rise), the sensor transmits an interrupt to the control panel indicating a fire alarm. The fire alarm control panel can adjust the sensor’s fixed temperature threshold for different installation requirements.

FEATURES

• Built-in 10-year battery offers continuous power for the life of the alarm;
