2.2.4 Connecting the Module
Figure 2.2.2 shows a standard schematic for connecting S2000-AR8 with the polling loop
controller and standard variants for connecting non-addressable detectors to the module.

Resistance of the monitored circuit wires shall not exceed 100 Ohm, while leakage resistance
shall be at least 50 kOhm. The monitored circuits are connected to the contacts of alarm and signal
outputs of detectors. Every monitored circuit of the module shall contain a 10 kOhm termination
resistor and, depending on the connection variant, can contain a relevant additional resistor.
2.2.5 Settings
2.2.5.1 Configuring
Variants A and B provide connecting fire detectors with recognizing such states of monitored
circuits as Norm, Fire Alarm, Open Circuit, and Short Circuit for the inputs with Input Type
2: Combined Fire.
For operating intrusion detectors Input Type is to be defined as 4: Intrusion,
5: Intrusion and Tamper, 6: Auxiliary, 7: Lobby, or 11: Panic, and the detectors are connected as
shown in Variant C.
The module enclosure open, a Tamper Alarm message is generated for all the monitored
circuits except for the one for which 4: Intrusion Input Type is given.
To monitor various systems, the Input Type in the polling loop controller configuration is to
be set to the value 6: Auxiliary. In case when the circuits should be monitored for faults, use the
connection variants A and B; otherwise, the connection variant C is suitable.
To get more information about inputs and ways to define them, please refer to operating
documentation on the polling loop controller and UProg.
2.2.5.2 Setting Address
S2000-AR8 provides storing addresses of the monitored circuits to communicate data over the
polling loop in the non-volatile memory. The factory address of an S2000-AR8 is 120, with this
address matching to the address of MC1. The addresses of the other monitored circuits are calculated
based on the address of MC1 by incrementing the address of every following circuit by 1.
To assign addresses, you should use the S2000M control panel or the UProg software utility to
send the polling loop controller one of the following commands:
– Set New Address;
– Edit Address.
