Overview
SIM Card Functionality
The PCS250G provides dual SIM card support for provider
redundancy. If a SIM card encounters network connectivity
problems, the PCS250G will switch automatically to the other SIM
card (only if installed). The PCS250G will then try to communicate
and upon a successful communication, an SMS trouble message
will be reported to the assigned recipients.
If connectivity problems occur on SIM card 1, the PCS250G will
attempt to switch to SIM card 2. When successful, an SMS
message will be sent to the assigned recipients informing them
of the SIM card connectivity problem. If the panel is disarmed, the
PCS250G will try to switch back to SIM card 1 after a 15 minute
delay. If there is a connection problem on SIM card 1, it will retry
to switch back to SIM card 1 every 15 minutes, or until the system
is armed. If the system is armed, an attempt to switch back to SIM
card 1 will occur only at midnight, otherwise SIM card 2 will
remain the reporting channel until the system is disarmed.
Detecting network connectivity problems on one SIM will result
in a trouble message. Once the original SIM card connection is
restored, a new SMS message will be sent to the assigned
recipients informing them of the restore.
Note:
The SIM Card 2 functionality is the same as SIM Card 1. Both
SIM cards must use the same communication method (both in GPRS
mode.
Tamper Switch Functionality
Upon removal of the PCS250G from its original installation
surface, or if the PCS250G cover has been removed, a tamper
switch open condition is recognized and is communicated to the
control panel.
Note: If desired that the tamper switch activates upon removal of the
PCS250G from its installation surface, a screw must be installed in
the tamper screw hole, refer to “System Components” on page 6.
Once a “tamper switch open condition” has occurred, the control
panel will generate an alarm (if armed), or send a trouble
message to the keypad(s) (if disarmed). The control panel will
also report a GPRS module tamper to the monitoring station and
to SMS recipients assigned to receive trouble notifications.
