Diablo DML-9LP Low Power Exit Probe Vehicle Detector

Diablo DML-9LP Low Power Exit Probe Detector

This low powered Free Exit Probe vehicle detector is perfect for solar powered applications. Connects to our new mini-loop using a completely new technology over standard inductive loops.

The DSP-7LP vehicle detector has been specifically designed for solar powered gate applications specifically for “fail safe” operations, such as on safety loops.

This detector will operate on any voltage from 10 to 30 volts AC or DC and draws approximately 1 milliampere with no vehicle on the loop. This micro-sized detector will automatically adjust its sensitivity level when used on different loop sizes. The detector loop inductance should be between 20 and 2000 microhenries.

The DSP-7LP detector has many of the same features as our standard DSP-7 but beats all competition for reliability, simplicity, and “no car” current consumption.

Features

• Designed for solar powered applications
• Plug and play
• Small profile, making it perfect for many installations
• Designed to be cross talk free between other loops
• Automatically compensates for loop and lead-in sizes
• Switch-less, self-adapting to most common installations
• Fail secure operation
• Wide low-voltage operation

General Specs and Instructions

LED Indicators: The green Power LED blinks once per second to indicate the detector is operating and powered. The red Detect LED will turn on when a vehicle is over the loop detection area.

Loop or Wire Failures: In the case of a loop circuit failure, the green LED flashes slowly (twice per second) for an open loop circuit failure. The green LED will flash fast (10 times per second) to indicate a shorted loop circuit.

Pulse Operation: This detector only outputs a single 125 ms pulse when the vehicle passes over the detection area. There is no option to operate in the presence mode.

Fail Safe vs Fail Secure: A fail safe detector will output “detect” when the loop circuit is failed. 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 DML-9LP is a fail secure detector. Note: Never use a fail secure detector on a safety loop.

Power: This detector is powered with 10 to 30 volts AC or DC. Approximately 1 mA current. The relay contacts are rated at 1 amp maximum.
