ALARM SENSORS
The following sensors are typically used on zone one. The two white
wires on the alarm control are to Zone one.
1. Canvas Snap Sensors. An intruder will probably not re-snap
the canvas when the siren goes off. Therefore we only want
the alarm to trigger the siren one time. Same thing is true if the
wind causes the canvas to unsnap.
2. Cable Wrap Sensors. If the cable is cut or disconnected we
only want the alarm to trigger the siren one time.
Zone one sensors are commonly used outside the boat to alarm
before an intruder boards the boat. Zones two and three are used for
protection after the intruder has come aboard the boat. The hatch/door
sensors are used with zone two. The door or hatch will alarm when the
door or hatch is opened. Typically the door or hatch will close when the
intruder leaves thus closing the sensor. The alarm will reset one minute
after the siren has howled for two minutes. If the door or hatch is closed
the alarm is again in a protection mode. Zone two will reset two times and
the siren will sound three times before Zone two becomes inactive. The
two green wires on the alarm control are to Zone two. Turning the alarm off
and on with the key-fob remote activates all zones again.
Zone three is typically used with a pressure mat. The wires to zone
three must be carefully hidden because cutting the wires between the
sensor and the alarm control will disable the pressure mat sensor. The two
purple wires on the alarm control are to Zone three.
It has to be understood that the Columbia Boat Alarm cannot stop or
cause a loud siren to sound whenever any of the alarm sensors is tripped.
The intent is to discourage a would-be intruder. An adequately charged
battery is essential for the operation of the alarm system.
A generic alarm sticker is used so an intruder cannot know whether
the alarm system is a Columbia Boat Alarm or some another alarm system.
