1.4 Functions and parameters
•
Inputs
The Compact-GSM module has 2 inputs (IN1 and IN2), which can be activated
depending on the setting with normally open (NO) or normally closed (NC) contacts wired
to COM connection point. Sensitivity of inputs is 100ms, which means event is generated
only if the input is activated for at least 100ms. Alarm monitoring delay is 10 seconds for
each input, which means if an input is activated, the module ignores new signals on the
respective input for 10 seconds from activation, so no alarm events are generated in this
period. When the 10s delay expires, the input becomes available again for activation.
•
Relay output
The relay output can be activated by initiating a call to the module’s phone number from
the 4 user phone numbers using identification of caller phone number, or from any phone
number without identification, depending on the setting. Relay control mode is
monostable, activation time is adjustable between 0-9999 seconds. Default setting: 1s.
•
User phone numbers
Maximum 4 phone number can be set, where the module sends reports with GSM voice
call and SMS. The maximum length of the phone numbers should not exceed 16
characters and international format should not contain “+” character (e.g. 0036….).
Already set phone number can be erased by pressing the „
#
” key instead of entering a
new number.
•
Call and SMS limitation
The module is equipped with internal call and SMS limitation. The function allows 50
outgoing calls and sending of 50 SMS messages per day.
•
Confirmation
Confirmation of alarms sent to user phone numbers (with GSM voice call) may be
necessary. In this case the module recalls the number until the user confirms the alarm
event. If the confirmation function is enabled, then the event can be confirmed by
pressing „
¾
” key and all alarm events (calls and SMS) in progress can be stopped by
pressing „
#
” key. By default the confirmation function is disabled.
