AVTECH Sound, Light & Entry Sensor (RMA-SLE-SEN) - Manual

The Sound Light & Entry Sensor (SLE) consists of a magnetically activated Proximity Switch, Magnetic Operator,
Light Sensor and Sound Sensor. The SLE provides real-time recognition of sound, light and/or entry such as a door
opening, closing, etc. The SLE box is designed to be mounted on a vertical surface such as a wall or pillar with the
light and sound sensors placed above so they are not blocked. This sensor is best suited for monitoring unmanned
closets, telecom rooms, remote data rooms or other low traffic facilities.
Each sensor can be adjusted to a desired sensitivity level in order to accommodate a wide range of applications.
To adjust the sensitivity of the sound sensor simply turn the calibration screw located on the top left of the unit
next to the sound sensor input. Turning the screw clockwise will make the sensor less sensitive to common noises
while turning it counter-clockwise will make it more sensitive. By default, the sound sensor will detect an alarm
condition with the sound of or similar to a smoke detector.
Light sensitivity is also adjustable. The sensitivity of the light sensor can be adjusted by turning the calibration
screw on the top right of the unit next to the light sensor input. Turning the screw clockwise will cause the sensor
to be less sensitive to light while turning it counter-clockwise will make it more sensitive to light. Turning the
screw all the way clockwise will almost disable the light sensor completely. By default, the light sensor will reach
an alarm state when exposed to daylight or standard office florescent lighting.
The Magnetic Operator of the Room Entry Sensor (component without wires) can be attached to any door, cabinet
or window that you wish to monitor using two screws. Place the Magnetic Operator at a point on the desired
surface edge so that the Proximity Switch (component with wires) can be fixed close to it (face to face), when
the door is closed. The Proximity Switch can then be mounted to the door frame in a very close adjacent location
(although not touching) to the Magnetic Operator, when the door is closed. Be sure there is room for the door to
open and close without disruption. This often means locating the sensor at the top of a door where it will be less
visible and less at risk. You will want to mount this inside of a secured room.
When the door is closed, the two components should be almost touching. In this position the Proximity Switch
is activated or in its normal state with the output from the Room Entry Sensor being ‘open’. When the door is
