3 General Setup
3.1 Input/Output Status Message
To determine the current status of the input and output terminals the STATUS com-
mand is sent to the system telephone number by a master phone as follows:
STATUS
The system will respond with a SMS text message as follows:
V5.XX
OPEN#RELAY OFF relay 1 in-active
CLOSE*RELAY OFF relay 2 in-active
INPUTA HIGH input A open circuit
INPUTB LOW input B closed circuit
INPUTC HIGH input C open circuit
INPUTD HIGH input D open circuit
AN1 05.6V analogue input 1 at 5.6V
AN2 00.0V analogue input 2 at 0V
SUPPLY VOLTAGE 10.7V post rectifier supply voltage
3.2 PAYG SIM Card Keep Alive
When using a Pay As You Go (PAYG) SIM card, to avoid SIM card deactivation, the
system will periodically call a dedicated telephone number (+441512834306) and
can send a SMS text message to keep the SIM active. Ensure the SIM card has suffi-
cient credit to make a call or text (the call will be answered and will be active for
15s). To setup the Keep Alive Text function the following SMS text message is sent to
the system:
KAT<space>number,frequency. enables periodic text message sending
e.g. KAT 07000000000,10. (text 07000000000 every 10 days)
KAT Off disables periodic text message sending
Frequency—number of days interval
The default settings for the Keep Alive Call, KAC, are a call to +441512834306 every
56 days. This can be changed using the KAC command:
KAC +441512834306,50. dials +441512834306 every 50 days
If the KAC fails, a message will be sent to the master numbers with the text
‘KAC#FAIL :(“. This can be due to the KAC number having been removed without
switching off the KAC function with ‘KAC OFF’. A manual call should be made using
the DIAL command.
