a 5 minute interval, this will also generate a Full Alarm
condition.
The jamming detection features in the Smart Home Box
and Solar Siren operate independently.
The Jamming Detection circuit is designed to
permanently scan for jamming signals. However, it is
possible that it may detect other local radio interference
operating legally or illegally on the same frequency. If
it is planned to operate the jamming detection feature
we recommend that the system is monitored for false
jamming alarms for at least 2 weeks prior to leaving the
Jamming Detection function permanently enabled.
BATTERY MONITORING
In addition to the battery monitor and low-battery
indicators in each device, the Smart Home Box will also
indicate a low battery status within any Passive
Infra-Red or Magnetic Contact Detector on the system
using the Event log.
ID CODE LEARNING
In order to prevent any unauthorized attempt to operate
or disarm your system, you must configure your system
to accept radio signals only from your own system
devices. All detectors and Remote Control Units have
their unique ID codes, and the Smart Home Box must
learn their codes individually for the system to operate
correctly.
For the PIR and Magnetic Contact Detectors, simply
pressing the tamper switch located adjacent to the PCB
will emit the ID code to the Smart Home Box instantly
with the Smart Home Box being set at the Security
Sensor zone.
For the Remote Control, pressing the button on
the Remote Control will emit the ID code to the Smart
Home Box instantly with the Smart Home Box being set
at the User setup mode.
For the Green Control or Green Remote/Sensor, please
pay particular attention to the device learning sequence.
Note: Green Remote/Sensor refers to the home
automation device that is built in transmitter.
HOME AUTOMATION
How to make your daily life more convenient? You
can set certain light fixtures or home appliances to work
at set times. Through settings of Holiday Arm or Night
Arm, you can achieve a better quality of life.
DISTANCE CONTROL & FEEDBACK
You can achieve the controlling function of enhanced
devices (i.e. devices with 868MHz radio frequency) via
GSM Gateway or IP Gateway if they are enabled. If
alarm condition occurs, the SMS message/mail will be
transmitted to you as a warning report.
BACKUP & RESTORE
There might be times when you wish to save a system
setting for later retrieval. You can achieve this
function via setting of backup & restore.
