8 / 18 page 5. Operation 5.1 ZigBee Network Behavior This section describes the various operational states a powered contact sensor reference design is able to occupy as it joins and leaves a ZigBee network. The input mechanism for operation utilizes a join button, S1. The red LED operates as output signaling information as the reference design traverses or occupies a functional state. Refer to the figure below for a pictorial representation of this process. OFF NETWORK No LED Flashes ON NETWORK No LED flashes NETWORK JOIN Six LED flashes ACTIVE NTWK SEARCH One LED flash per two seconds LEAVE NETWORK Three LED flashes per two seconds NETWORK STATUS Six LED flashes IDENTIFY Two LED flashes per two seconds for three minutes Button press, or power cycle No joinable network found for three minutes Two button presses Three button presses One button press >1 second TAMPER DETECTED Alarm message sent If button held >4 seconds is released No response from network, wait 15 minutes No response from network -or- 4 button presses -or- power cycle REJOIN NETWORK No LED flashes One button press >1 second A button press resets three minute timer Button held >4 seconds activates tamper monitoring Blink cycle ends Joinable network found Mode time out Mode time out Figure 5.1. Device Operation State Diagram 5.1.1 First Time Contact Sensor Power-up After the hardware has been powered for the first time, the device will be in a factory default mode and will be placed in the ACTIVE NTWK SEARCH state. If the dimmer switch successfully joins a network is powered off at a later time, upon re-powering, it will enter the REJOIN NETWORK state instead of the ACTIVE NTWK SEARCH state. 5.1.2 OFF NETWORK State This state is a condition where the design is not connected to a network and is not searching for a network. To leave this state and enter the ACTIVE NTWK SEARCH state, press the S1 button one time. 5.1.3 ACTIVE NTWK SEARCH State This state is a condition where the contact sensor is actively searching for a network but has not yet joined a network. While in this mode, the D1 LED will flash once every two seconds. This operation of actively searching for a network will remain for up to three mi- nutes. If no network is found by the three minute time limit, the contact sensor will enter into the OFF NETWORK state. Power-cycling or a button press while in this state will reset the three minute timer, while keeping the contact sensor in this state. If a network is found it will leave this state and enter the NETWORK JOIN state. 5.1.4 NETWORK JOIN State After a contact sensor leaves the ACTIVE NTWK SEARCH state and enters this state, the D1 LED will flash six times to indicate suc- cessfully finding and joining a network. This state is temporary and will place the contact sensor into the ON NETWORK state once the LEDs complete their flash sequence. Power cycling will only impair the LED flashes, and will not prevent entry into the ON NETWORK STATE once the power is reapplied.
