INTRODUCTION
The
200-WS-21-A Dual Set Point Wind Alarm
includes a rotating cup style anemometer (NovaLynx
200-WS-01B) and internal alarm buzzer. Two independently controlled relays are provided to operate
external equipment such alarm lights or sirens. The Wind Alarm can function as an irrigation or
fountain over-ride controller.
The back-lit LCD display is easily visible through the transparent cover. With the cover removed the
unit is programmed by push-button controls without the need to connect a computer. All set points
and the maximum wind speed value are stored in non-volatile memory. DIP switch settings select the
units (mph or kph) and enable/disable the buzzer.
Programmable Features:
Alarm Set Point
Wind speed threshold for the alarm
Channel 1
0-100 mph or 0-160 kph
(Default 25 mph / 40 kph)
Channel 2
0-100 mph or 0-160 kph
(Default 50 mph / 80 kph)
Alarm ON Delay
0-99 seconds before alarm/ relay activation
(Default 5 sec)
Alarm OFF Delay
0-99 seconds before alarm / relay de-activation
(Default 5 sec)
When in alarm mode, a blinking LED indicates which relay(s) are active. Each relay can be connected in
the normally open or the normally closed mode.
It is the responsibility of the installer to properly
insulate any connections to the relay terminals, especially if high voltages are present. It is also
important to provide an earth grounding wire to protect the controller from static discharge,
whether or not the relays are connected.

SPECIFICATIONS
The anemometer is rated for wind speeds up to 125 miles per hour (201 kph) and has a starting
threshold of approximately 1.2 mile per hour (2.0 kph). The Wind Alarm LCD can display speeds up to
99.9 (mph or kph), but the control logic continues to operate above this limit.
