WSD-1 (smoke) and WHD-1 (heat) are wireless detectors on a 444.4 MHz mesh network.
They work with the WCP-1 panel, or interconnect on their own.
Up to 50 devices per mesh network; 90 dB alarm at 1 m.
A wireless fire alarm system makes installation much easier. With no cable, we save 90% of installing time. System and maintenance costs are also much lower.
SMOKE DETECTOR
The WSD-1 wireless smoke detector works with the FireSmart wireless control panel WCP-1.
It also works as an interconnect device. It can connect with other smoke, heat or combined detectors, even without the control panel. It can also connect to a wireless manual call point and a wireless fire alarm bell.
The detector uses a photoelectric sensor. This sensor is sensitive to larger smoke particles. These appear in the early stage of slow-burning fires, such as those from electrical wires.
HEAT DETECTOR
The WHD-1 has a highly linear thermistor circuit. A specially designed cover protects the thermistor and still allows maximum airflow. The circuit gives a voltage proportional to the ambient temperature.
The sensor enters alarm mode when the temperature passes a preset threshold. The threshold is either a fixed 54 degrees Celsius or a rise of 8 degrees Celsius per minute.
One MESH-Network of interconnected detectors can hold a maximum of 50 devices. These include smoke detectors, heat detectors, manual call points (MCPs) and wireless horns or sirens.
When used with a fire alarm control panel (FACP), the WHD-1 sends an interrupt signal to the panel in case of a fire alarm.
COMBINATION OF SMOKE & HEAT DETECTOR
A combination detector senses both smoke and abnormal heat in one unit. It combines a photoelectric smoke sensor and a heat sensor.
Dual detection: Smoke sensing finds smoldering fires with a lot of smoke. Heat sensing finds fast, flaming fires with less smoke. Together they improve detection.
Fewer false alarms: The detector checks both smoke and heat. It can tell steam or dust from a real fire.
Versatile installation: It suits places where a smoke detector alone may false-alarm, like kitchens and bathrooms.
Cost-effective: One dual-function device can cost less than buying separate smoke and heat detectors.
