Mounting The Antenna - DSC GSM 1000 Installation Manual

3.3.7 RNG (Ring) Terminal
When the GSM 1000 receives a phone call, it will activate the RNG terminal on the GSM 1000 Module. Please
refer to Option 05 to enable ring detect. This output may be used for the control panel which allows it to
answer incoming downloading calls via the GSM network.
Note: Downloading is only available on networks capable of SIA communications.
Please refer to the control panel programming instructions in this manual for programming the appropriate
input (i.e. Zone or PGM) as Links Answer or Forced Answer.
Please refer to the connection diagram in this manual for proper connections between the GSM 1000 and
control panel.
3.3.8 Panic Terminal

3.4 Mounting the Antenna

Note: The GSM 1000 antenna must be mounted above ground level. Installing the antenna as high as
possible is best. If necessary, Antenna Extension Kits are available from you distributor (see the "Relocating
the Antenna" section below). The antenna should be installed in a physically secured location to avoid
tampering. Also, avoid placing the antenna under any sort of RF (Radio Frequency) shielding, such as metal
roofing or overhang. The GSM 1000 works best when the antenna is installed in an unobstructed "line of
sight" to the GSM network receiver.
The antenna should always be connected to the GSM 1000 whenever it is operated. The unit will not function
properly if an antenna is not installed.
3.4.1 Antenna Tamper Switch
When the Panic terminal is temporarily shorted to ground,
the GSM 1000 will dial the phone number that is
programmed in the panic phone number option. Please
refer to Option 09 in "Programming the GSM 1000
Module" section. This phone number has to be a direct
access line, it can not be dialed to a PBX and then into
an extension.
Note: This input is a 24-hour, silent terminal and the
Panic phone call will be connected through the cellular
network.

In addition to the GSM 1000 network supervision, the
Antenna Tamper Switch module may be used to further
increase the security of the antenna connection to the
GSM 1000 module. Please refer to the diagrams below
for installing the tamper switch.
Note: This module is only effective if the antenna mast
is connected to the antenna bracket of the GSM 1000
module.
