Explanations for Figure 1:

DIP switch package
for setting individual address and operating mode of the
interface (see:

STATUS
LED
indicating as follows:
blinking light – data exchange with the control panel;
steady light – no communication with the control panel.
3 –
DB-9 male socket (port RS-232)
. Enables the interface to be connected to
computer or other external devices. Cross-linked cable with female connectors
on both sides (so called, null modem cable) should be used.
Description of terminals:
TMP
- tamper circuit input of the interface (NC) – if not used, it should be shorted
to common ground.
COM
- common ground.
CKM
- clock.
DTM
- data.
+12V
- power
input.
2. Installation
Disconnect power supply before making any electrical connections.
The INT-RS interface is designed for indoor installation, in spaces with normal
humidity of air. The device installation place is to ensure protection against
unauthorized access.
1. Secure the device electronics board in the enclosure.
2. Using DIP switches, set a suitable address of the device and select its operating
mode.
Note:
The event reporting mode requires that the

] option be activated in the control panel. If the ETHM-1 module
is also connected to the control panel at the same time, events will only be sent
by means of the device with a lower address.
3. Connect the CLK, DAT and COM terminals by means of wires to the keypad bus
on the control panel mainboard. It is recommended that the unscreened straight-
through cable be used for making the connection. If you use the twisted-pair type
of cable, remember that CKM (clock) and DTM (data) signals must not be sent
through one twisted-pair cable. The wires must be run in one cable. The length of
cables must not exceed 300 m.
4. Connect the enclosure tamper contact cables to the TMP and COM terminals. If
two modules are installed in the enclosure, the TMP input of one of them is to be
shorted to the common ground, and the tamper contact cables connected to the
TMP input of the other module.
5. Connect the power supply cables to the +12V and COM terminals. The interface
need not necessarily be supplied from the control panel mainboard. The devices
