Communicating Data Over the RS-485 Interface
The unit receives commands from and transmits messages to the network controller over the RS-
485 interface. The status of communication is indicated by the COM LED as shown in the table below.
Communication Condition
1. Data are communicated over the RS-485 interface
2. Communication over the RS-485 interface has been lost
The unit provides buffering of the events on their transmitting. The capacity of the buffer is 66
events.

Safety Precautions
3.1.1. The unit's design meets the requirements of electrical and fire safety according to Russian
Standards ГОСТ 12.2.007.0-75 and ГОСТ 12.1.004-91.
3.1.2. The unit has no circuits under hazardous voltage.
3.1.3. Do shut off the unit's power before mounting, installing, or maintaining this one.
3.1.4. Mounting and maintaining must be performed only by qualified staff with the second or
higher safety certification level.
3.2
Preparations for Use
3.2.1
Before connecting the unit to the RS-485 interface, the unit must be assigned to a unique
network address. This address must not be the same as the address of another device connected to the
same interface RS-485.
3.2.2
If a wrong address is assigned to the unit it can be reset to 127 without disconnecting from
the RS-485 interface and connecting to a PC. Remove the cover of the unit and perform the following
combination of presses on the unit's tamper switch: long-long-long-short (dash, dash, dash, dot). A
long press means pressing the tamper switch and holding it pressed for 0.5 to 1.5 second while a short
press means pressing the tamper switch and holding it pressed for shorter than 0.5 s. If the action has
succeeded then COM LED pulses four times per second for 4 seconds.
3.2.3
If necessary, change other configuration parameters of the unit to fit the unit's functions.
3.2.4
Attach the unit at any convenient place (the unit can be installed on walls, behind
suspended ceilings and on other structures of the protected premises near executive devices at places
protected against atmospheric fallouts, mechanical damage, and unauthorized access).
3.2.5
Mount and wire the unit as shown in Figure 3 in accordance with your applicable local
standards, codes, regulations, and ordinances (РД 78.145-92 for Russia).
3.2.6
If a single power supply is in use (the configuration parameter Both Power Inputs
Monitoring is set off), this one can be connected to any power input of the unit.
3.2.7
If the unit and the network controller are connected to different power supplies, their 0 V
circuits should be coupled.
3.2.8
Unless the unit is the end (the first or the last) device in the interface bus, remove the
jumper which is near the contacts "RS-485A" and "RS-485B".
