LEVEL
(Liquid Level)
"Clean" contact NC H24 (normally closed) when the DEFENDERTECH liquid level is acceptable. It will open when the
level is in "reserve" (at least 60 "of autonomy available).
It is recommended to bring the contacts to the control panel and create an unarmed area for signaling purposes.
Note: This contact can be used to assign other functions, see p. 14 "special features"
STATE
(system status / failure signal)
When the appliance is disarmed or switched off, the "Clean" NA contact (normally open) will be close in when the
machine receives the command to arm.
The tamper placed on the left side of the appliance "is in series" with this output.
If a malfunction occurs, the "STA" contact will open.
It is recommended to bring the contacts into the central unit and create a delayed zone of 0.5 '' not alarmed in order
to signal the status of the machine.
Note: This contact can be used to assign other functions, see p. 14 "special features"
SHOOT
"Negative OC" output (normally off) during the firing phase.
READY
"Negative OC" impulsive output (normally off), in order to signal the "burner ready" status.
The output will be activated when the appliance is armed and the burner will have reached the 100%, it will only be
desactivated when the burner temperature has fallen below the allowed threshold.
Electrical connection
Note: Prepare a dedicated 220V power supply line,
with a switch and adequate protections.
