This sensor is designed to detect 3 different troubles:
1. Detecting the vibrations made by an intruder trying to break a window or door.
-There are 2 different ways of determining these vibrations as well:
a. Gross Attack - detect a violent blow sufficient in length to trip sensor. A individual blow of adequate force.
b. Pulse Count - detect a sufficient number of less violent blows (rapping or tapping). Many individual blows in a designated time frame.
2. Detecting a window or door opening or closing.
-To have this element you must be sure to activate the Reed Switch. This will be better explained later.
3. Detecting tamper situations, such as an intruder removing the sensor cover.
This options cause these sensors to be a bit complicated and the steps to set it up and mounting quite important. Before we get too in depth with that, we need to be familiar with the components of the sensor. Here is a diagram of what you should see inside. To view the following examples remove the cover.
I highlighted the Green LED because it will be important later.
The First Step is to decide whether or not you would like the sensor to detect if the door or window is opened or closed.
There is a filament in the sensor that is designed to detect these openings and closings. We need to place the magnet (the smaller contact) in the designated area on the door or window lining up with the arrow on the Larger sensor itself as shown below.
That is why we must keep this in mind before mounting the sensor, because we really have to mount 2. To determine what you should look for, place them flat on the table with the 2 arrows aligned; they should have no more than a quarter of an inch between them. With this in mind you can continue to mount the sensors.
**Important: Always mount the shock sensor so that the detector is on the frame and not on glass, solid, or hollow-core doors.
There are 2 possible ways of mounting this sensor:
1. Horizontally, parallel to the ground
2. Vertical, perpendicular to the ground
Its important, when mounting either of these 2 ways, that the "Shock Element" needs to be orientated correctly. When mounting it Vertically, the shock element must have the screws Facing Downward as shown below.
On a Horizontal surface, any orientation is allowed, but certain sensor element orientations are better
than others. The element is much better at detecting horizontal vibrations Perpendicular to its Writing than parallel.
-Make sure that you mount the sensor in a location where the structure can transmit vibrations to the sensor.
-Make sure the window fits snugly in the frame and does not move or rattle.
If this is done properly, the sensor will work appropriately.
Once the sensor is set up and mounted properly, it is very important that we adjust the sensitivity of the sensor to the desired level. To do this we need to realize 2 components labeled in the first photo:
- The Dip Switched
- The Green LED
These are very important in the sensitivity programming element of the sensor.
-The Green LED is used to determine if something is sensitive enough or too sensitive for the situation. You can test the sensor by tapping on the frame on which it is sitting. This Green Led will indicate when the sensor detects a potential alarm. If the force is enough to set off an alarm (Gross Attack), the Green LED will blink for 4 seconds. If the tap is not high enough to set an alarm, it can still be received as a pulse instead (Pulse Count) it will blink for 1 second. To change the sensitivity settings on these 2 attributes we must use the Dip Switches.
- The Dip Switches:
As you can no doubt see, there are 6 Dip Switches:
-1&2 adjust the Pulse Count
-3&4 adjust the sensitivity setting of Gross Attack detection.
-5 enable/disable reed switch.
~ON for enabled or OFF for disabled
-6 is not used.
The above stated attributes (pulse count, gross attack, and reed switch) are explained previously.
