DSP-40S Vehicle Detector
Fail Safe vs Fail Secure
A fail safe detector will output “detect” when the loop circuit is failed. This is always useful on a
safety loop. On the free exit loop this will keep the gate open until the situation is fixed. This is
useful in applications where it is important to allow traffic flow to continue. A fail secure detector will
never output “detect” when the loop circuit is failed. This will keep the gate closed. This is useful in
high-security areas or installations where containment is needed. The DSP-40S is a fail safe
detector.
Note:
Never use a fail secure detector on a safety loop.
