Note:
The unit re-requests programming after a firmware update; the version number is updated and viewable via C24 Com-
munications.
Note:
Unit must not be powered down while a firmware update is in progress.
Note:
LE4000 will not process remote firmware update requests while the following troubles are present.
• Input Power Trouble
• Low Battery Trouble
6.10 Low Power Radio Shutdown
When the battery voltage reaches the low battery threshold of 6V, the LE4000 turns off the radio to prevent unnecessary network
registrations. In this state, no events are communicated.
Radio shutdown is indicated by the LEDs as follows:
l
Red LED indicates low battery trouble.
l
Two RRSI LEDs blinking on/off together indicates the radio is not ready.
6.11 SMS Command and Control
To enable SMS control of the security panel, do the following.
6.11.1 Arming/Disarming the Security Panel
1. Set a PGM output to Remote Arming in C24 Communications.
2. Ensure this PGM output is connected to a relay to their security panel zone.
3. Set up the zone on the security panel as Momentary or Maintained arming.
l
For Momentary key switching, configure the Communicator PGM with a time field of 05. In this configuration, both
arm and disarm generate the pulse.
l
For Maintained key arming, configure the Communicator PGM with a time field of 00.
4. Optionally, the communicator can detect panel arm state by configuring a panel PGM output to detect arm state, then con-
necting that output through a relay to a communicator zone also configured to follow panel arm state.
6.11.2 Remote Control of PGM
1. Set one or both PGM outputs to Remote Control PGM configuration. A PGM can be latched or timed:
l
Setting the PGM timer to 00 causes the PGM to be latched. The PGM will not turn off unless the turn off command
is received.
l
Setting the PGM timer to a value between 1 and 255 seconds causes the PGM to be timed. The PGM activates for the
programmed duration.
2. Via C24 Communications, program the phone number and access code used for SMS command and control.
l
Up to 6 different phone numbers can be programmed to perform SMS command and control.
l
The password can be 4 to 8 alphanumeric characters and is not case sensitive.
The SMS command and control can be sent in the following format:
For arming/disarming the security panel
Arm <access code>, example Arm 12345678
For activating/deactivating a specific PGM
Activate <PGM #> <access code>, Activate 1 12345678
