The address set must be different from that in the other devices connected to the keypad bus
of the control panel (the control panel does not support devices with the same address).
4.3 Installation of antenna
The INT-GSM module is delivered with an antenna. The antenna can be replaced with
another antenna mounted on the enclosure or at some distance from it. If this is the case,
you will need the IPX-SMA adapter.
Using the antenna mounted at some distance from the enclosure is recommended wherever
thick masonry walls, metal partitions etc. may decrease the range of radio signal at the
module installation place.
The antenna must not be installed in parallel to low-voltage electrical wires, or it can affect
performance of the antenna.
4.4 Connection
The module can be connected directly to the alarm control panel or to the ETHM-1 Plus
module. It is recommended that unshielded non-twisted cable to be used.
4.4.1 Connecting to the alarm control panel
Fig. 4. The way of connecting the module with the alarm control panel.
1. Connect the +12V, COM, DTM and CKM module terminals to the control panel terminals
(Fig. 4). To connect the +12V and COM terminals, use flexible conductors with a cross-
section of 0.5-0.75 mm
2
, or rigid conductors with a cross-section of 1-2.5 mm
2
. If you use
the “twisted pair” type of cable to connect the DTM and CKM terminals, keep in mind that
the CKM (clock) and DTM (data) signals must not be transmitted using one pair of twisted
wires. The wires must be run in one cable.
2. If the control panel is to be configured via the module using the DLOADX program,
connect the module RS-232 port to the control panel RS-232 port. Depending on the
control panel, use the following cable to make the connection:
INTEGRA with connector socket of RJ / INTEGRA Plus type:
RJ/PIN5
INTEGRA with connector socket of PIN5 type:
PIN5/PIN5
The above mentioned cables are available in SATEL's product offering.
