Pstn Modem; Gsm Modem - Pyronix Enforcer 32-WE Programming And Installation Manual

6.11 PSTN Modem

IMPORTANT NOTE: TURN OFF THE MAINS BEFORE DISCONNECTING THE PSTN MODEM
The PSTN modem card is used to enable the Enforcer 32-WE to communicate either via contact ID,
Fast Format, SIA or SMS texts via a telephone line. It will also enable remote uploading/downloading.
Before making these connections, all power must be disconnected from the system.
NOTE 1: The telecom ground terminal (TE) should ALWAYS be connected to earth in order to
maximise the effectiveness of the transient voltage protection on the unit.

6.12 GSM Modem

IMPORTANT NOTE: TURN OFF THE MAINS BEFORE DISCONNECTING THE GSM MODEM
The GSM modem card is used to enable the Enforcer 32-WE to communicate either via Contact ID,
Fast Format, or SMS texts via a SIM card. It will also enable remote uploading/downloading.
6.12.1 Antenna
The supplied antenna will need to be connected to the Enforcer 32-WE GSM and placed in a
suitable area where the signal strength at it's maximum.
6.12.2 Digi GSM Information
NOTE: When SMS messages are sent, the GSM module uses the 'voice channel'. However, when
the panel needs to be programmed remotely using the UDL software and modem, a data channel
must be used. It is advisable to find out from the network provider whether or not they offer
data service, as listed below:
• Some networks provide the data channel as a standard service with pay as you go and contract
SIM cards.
• Some networks have to enable the data channel separately.
• Some networks use a different phone number for the data channel from the GSM number of
the SIM card.
• Some networks automatically recognise the data call from the voice call.
Example: At the time of writing, "O2" uses a separate data number from the GSM number. While
"T-Mobile" automatically recognises data call from voice call. "Vodafone" and "Orange" do not
offer any data number or channel and therefore cannot currently be used for remote
upload/downloading.
