6 INT-GSM SATEL
TMP
– tamper input (NC) – if not used, it should be shorted to common ground.
A RS485 B
– RS-485 port for connection with the ETHM-1 Plus module.
DTM
– data (communication bus).
CKM
– clock (communication bus).
4. Installation
Disconnect power before making any electrical connections.
It is not advisable to power up the module if the antenna is not connected.
The installation to which the module is to be connected should be provided
with:

2-pole disconnector,

short-circuit protection with a 16 A time delay circuit breaker.
The INT-GSM module should be installed indoors, in spaces with normal air humidity. When
selecting the mounting location, remember that thick masonry walls, metal partitions, etc. will
reduce the range of radio signal. It is not advisable to install the module in close vicinity to
electrical installations, because this can result in malfunctioning of the device.
4.1 Installation in enclosure
The enclosure in which the module is to be installed shall meet the requirements
for fireproof enclosures.
If the module is to be directly connected to the alarm control panel, it should be installed in
the same enclosure with the control panel. This will facilitate connecting the RS-232 ports of
control panel and module.
1. Secure the module electronics board in the enclosure.
2. If the module is to supervise the enclosure tamper switch, connect the tamper switch
wires to the TMP and COM terminals. Otherwise, connect the TMP terminal to the module
COM terminal.
4.2 Setting address
Setting the address is required if the module will be connected to the keypad bus of
the alarm control panel. If the INT-GSM module will be connected to the ETHM-1 Plus
module, you do not have to set the address.
To set an address, you must place jumpers across the ADDRESS pins. Table 1 shows how
to use jumpers in order to set a specific address ( - jumper on; - jumper off).
Address
0 1 2 3 4 5 6 7
Pins status
Table 1.
Set an address in the module within the range:

from 0 to 3, if it is connected to INTEGRA 24 or INTEGRA 32 control panel,

from 0 to 7, if it is connected to another INTEGRA or INTEGRA Plus control panel.
