HOLDB R120m. 120 minute delay on Input B; repeat every 120 mins (2 hours)
Holdb 2s 2 second delay on Input B
holda 0 turn off delay on Input A (set delay time to zero)
NB. If the input is not specified then the default input is Input A
4.14 Silencing the Alarm
The bell –ve wire can be routed through the relay COM and NC terminals onto the bell. This al-
lows the relay to break the connection when active and silence the alarm. Whilst the bell is
sounding the SILENCE command can be used to silence the bell. The connection is re-
established once both inputs return to the idle state (i.e. the alarm panel is reset)
silence activates the output relay until the input is idle
5 Setup
5.1 SIM Keep Alive Text
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 mes-
sage to keep the SIM active. Ensure the SIM card has sufficient 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 follow-
ing 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 setting 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.
5.2 Signal Strength Indicator
When setting up the system it is important to know the strength of signal for reliable operation. To
receive a message showing the Received Signal Strength Indicator (RSSI) the CSQ command is
sent to the system as follows:
CSQ
When the system SIM card has sufficient credit a SMS text message is sent to the number which
sent the command displaying the current RSSI.
e.g. >RSSI 21
It is recommended that the minimum signal level for the installation is 15 (-83dBm) to ensure reli-
able operation. The system will operate below 8 (–100dBm) but may become unresponsive at
times.
