Magnetic Sensors
WSK-WGI Wireless System Gateway
2.3.1 Environmental Specifications
2.4 Magnetic Sensors
Magnets must have a holding strength of 10 lbs or greater. Use either the north or south pole of the magnet to activate sensors.
2.4.1 Mesh Formation Magnetic Sensor
The mesh formation magnetic sensor (refer to Figure 2.2) transitions the gateway in and out of mesh formation mode. The initial activa-
tion of the sensor puts the gateway in mesh formation mode (as long as it contains a profile). A subsequent activation of the magnetic
sensor transitions the gateway out of mesh formation and into the initial mesh restructuring and normal mode. The gateway can be
placed back into mesh formation mode by activating the magnet sensor once again. The LED next to the profile magnet sensor turns on
green for ½ a second when the sensor is activated..
2.4.2 Magnetic Sensor
The square magnetic sensor can be used to start a communication session with SWIFT Tools. See Section A.3 on page 45 for more infor-
mation.
2.5 LED Indicators
The two LEDs on the gateway blink in the same pattern to allow the LED to be viewed from any angle. LED patterns are explained in
Appendix D.
2.6 Installing the Gateway
2.6.1 Before Installing
Choose a location for the gateway that is clean, dry, and vibration-free. The area should be readily accessible with sufficient room to eas-
ily install and maintain the gateway. Metal obstructions impede the radio frequency communication and should be avoided. Carefully
unpack the system and inspect for shipping damage if any. All wiring must comply with the national and local codes for fire alarm sys-
tems.
Minimum signal strength level needed at the receiver for a secondary path or
primary path with weak link trouble reporting disabled.
Must be 18 dBm higher than the noise
floor down to a minimum of -80dBm
1
Maximum ambient noise level
Maximum RF Power Output
+17dBm (Tx power level without antenna)
Radio Frequency
Lower ISM Band (902 - 928MHz).
1
Ensure that the primary path signal strength level is within recommended guidelines to assure proper communication in the
mesh network.
