Overcoming a sleeping device
The device is battery powered and is designed to enter sleep mode when not transmitting
to save battery power. Sometimes during system setup you would want to retrieve
information (i.e. IEEE address, short address) from the device. The device needs to enter
temporal wake mode to stay connected.
Operation:
1. Hold press on auxiliary key and binding key at the same time until you see the
indicator
flash in red twice
. Then release the keys.
2. Z311C broadcasts an announce packet with an IEEE address and a short address
information to the air. There is
2 minutes of active period
to communicate itself with
other device on the network.
Periodical Heartbeat Notification
In a security system, it is important to know the condition of each zone device required by
most software or hardware monitoring system or end user. To meet this need, Netvox
engineer came up with a mechanism called the heartbeat of a device implemented within
the firmware of Z311C and other Netvox security zone devices.
When Z311C had just registered itself to the security CIE system,
it sends the very first
heartbeat signal right after a successful registration.
After that it initiates a periodic
heartbeat and send to the security CIE system in every one hour by factory default which
is configurable through software with heartbeat cluster implemented (for application
developer or Netvox ZiG-BUTLER user). The heartbeat contains heartbeat information,
low battery power notification and alarm status.
The configurable heartbeat period range is between 30 seconds to a maximum of 604800
seconds (7 days) anything bellow or above that range is invalid value. When configuring
the heartbeat period, anything above 10 minute will take the step of 10 minute increments.
That will be 20 min, 30 min, 40 min, etc. If you give any other number, the Z311C will take
the least value. (i.e. as you typed in 35min value, the Z311C will take 30 min value)
*Such heartbeat can be configured via ZiG-BUTLER please go to

section.
