Advanced Commands

Debouncing Inputs

This feature prevents the SMS Lite from sending multiple messages when connected to devices such
as float switches, which can switch on and off several times before settling due to contact bounce.
You can program a delay before the text message is sent by the SMS Lite.
The trigger point / device that is connected to the SMS Lite must stay in that state for the 'debounce'
time that is set, before the SMS Lite will send a text message alerting you of a status change.
The delay is configurable, and you can select one of the following options: 0, 5, 10, or 30 seconds, or
1, 5, 10, or 15 minutes. Only these values are allowed.
The debounce value is applied to all inputs - you cannot specify different values for each input.
Program the 'debounce' option and value using the following instruction:
#[PIN][space]<object>:<item>=<value>[dot]
#12345 site:debounce=value. (e.g #12345 site:debounce=1min)
The value must be written in the following format "0sec", "5sec", "10sec", "30sec", "1min", "5min",
"10min", "15min"
For example:
#12345 site:debounce=10sec.

Clearing Configuration Settings

To clear all of the SMS Lite configuration settings, use the message:
#[PIN][space]Defaults[dot]
Note: This command will also clear all the programmed telephone numbers. After issuing this
command you must re-register the Master User (Ph1) before proceeding.

Supply Voltage Alarm

If the SMS Lite supply voltage drops below 10.5V DC, Ph1 will receive this notification message:
The supply voltage at <site> has gone low.
When the voltage increases above 11.5V DC a supply voltage message will be sent:
The supply voltage at <site> has returned to normal.
Tip – Supply voltage alarms do not escalate like input alarms.
Supply voltage can be queried at any time using the STATUS command
