4.2.6. Description and mounting of devices to Low Press input
Connect a two-wire line to the Low Press. input for connection with a pressostat contact, balance
or other devices registering a Fault condition in the extinguishing installation. The line is balanced and
it is monitored for interruption and short circuit. Install the two resistors to the switch terminals as
shown in the connecting diagram to monitor the condition (Drawing 6).
Drawing 6
Set up the input active status: OPEN or CLOSED contact from menu System functions > Set
up > Input/Outputs > Low Press input.
Attention! The active status of the default parameters is OPEN contact of the switch in order the
fire extinguishing control panel to accept the function Leaked extinguishing agent or Fault condition.
4.2.7. Description and mounting of devices to “Exting” output
Connect a two-wire line to the Exting output for connection with a magnetic valve or other device
to activate the extinguishing automation. The line is balanced and it is monitored for interruption and
short circuit. Install a diode 1N4004 or similar to the executive device terminals in the direction as
shown in the connecting diagram as the valve winding resistance shall be in the range: 30Ω ÷ 3kΩ.
(Drawing 7).
Install a parallel resistor 3kΩ / 0.25W and a serial diode 1N5401 on the line if the winding
resistance is less than 30Ω (Drawing 8).
Connecting diagram if the winding valve active resistance is from 30 Ω to 3к Ω
