Double-Zone balancing
Double zones without EOL resistor can discriminate 5 conditions on the
entire terminal:
• standby on both zones
• alarm on zone 1 and standby on zone 2
• alarm on zone 2 and standby on zone 1
•alarm on both zones
• tamper (wire cutting)
For each of these, the control panel reads different resistance values on
the terminal, expressed below in Ohm.

Double Zone balancing with EOL
Double zones with EOL resistors can discriminate 6 conditions on the
entire terminal:
• standby on both zones
• alarm on zone 1 and standby on zone 2
• alarm on zone 2 and standby on zone 1
•alarm on both zones
• tamper (wire cutting)
• tamper (short-circuit)
For each of these, the control panel reads different resistance values on
the terminal, expressed below in Ohm.

Wiring and balancing rollerblind/
shock sensors
It is possible to choose between two types of balancing for Rollerblind and Shock
sensors:
• Normally closed (N.C.)
• Single balancing (NC with EOL)
The following table compares the protection level of rollerblind/shock sensors using the
two balancing options provided by the control panel.
