GENERAL DESCRIPTION
EK-WL8-OV/AU is a wireless 3-in-1 device
equipped with an optical smoke detector and a
voice annunciator and visual alarm device
(VAD).
The
device
analyzes
associated with fire and the way these factors
change through time. An alarm signal is
generated when the smoke level inside the
optical chamber exceeds a certain threshold.
The signal travels through repeaters to the
translator module, which then informs the main
control panel about the emergency.
The advanced design of the optical chamber guarantees a very high level of dust
protection, effectively increasing the time between maintenance procedures. The
device can also automatically connect to different repeaters which makes the
wireless connection robust and reliable.
The device is supplied with a mounting kit.
The product complies with the requirements of the AS ISO 7240.7, AS ISO
7240.23:2014 and AS ISO 7240.25 standards.
FEATURES
• Adjustable photo sensitivity – low, normal or high
• Bi-directional wireless communication
• Intelligent algorithms
• Sound synchronization with same devices in the system
• Tamper switch
• 10-year battery life
• Self-optimizing wireless frequency and amplitude algorithms
• Patented design of the smoke chamber
• Ability to operate in a thread of similar devices
• 5-year warranty
