R
is for the resistance of the wires between the S2000-SP2 rev.02 and the fixed fire-fighting

system, [Ohm];
is for the effective resistance of the explosive squib (bridgewire), [Ohm].

The preferred value for the current-limiting resistor R
value in E24 series.
The R
resistor must be of enough power, especially if the activation time exceeds one second.

For example, when the unit is fed by a 24 V power supply, the resistance of connecting wires is
less than 0.3 Ohm, the squib resistance is 6 Ohm, and the squib operating current is 0.1 A, then the
resistance of the additional resistor is selected as 160 Ohm.
Several appliances (light signs, sirens and so on) can be connected in parallel across a single
output if the following requirements are met:
- In the quiescent mode the appliances are turned off;
- The total current per the output doesn't exceed the maximum allowed one (3 A);
- Mounting is conducted in accordance with the schematic shown in Figure 2.2.7.

2.2.5 Programming the Unit

Setting an address:
Prior to operating the unit, please assign it with a unique address in the PL. This address shall not
be the same as any device connected to the same PL may have.
The unit occupies two addresses in the PL address space and provides storing them in the non-
volatile memory.
The addresses are adjacent, that is the unit occupies two addresses in series.
The unit comes with addresses 126, 127.
To set the addresses, please send one of the following commands for the polling loop controller
in use from the S2000M control panel or a PC with installed UProg Configuration Tool:
– Set Device Address;
– Change Device Address.
A Set Device Address command assigns an address to the unit without regard to what address
this one is assigned to at the time. This option can be used when the same address is erroneously
