Diablo DSP-19 Low Power Mini-Loop Vehicle Detector

Diablo DSP-19 Low Power Loop and Mini-Loop Vehicle Detector

The DSP-19 is specifically designed to be installed into a LiftMaster® model CSW24 operator or other models that use the same plug-in loop detector. The very low current draw and low voltage range is ideal for solar applications.

The DSP-19 can be connected to a standard inductive loop or one of Diablo Controls mini-loops. The Diablo Controls mini-loop is a small “pipe shaped” device approximately 4-1/2” by 1” and is designed to be buried in the ground to detect vehicles. If the mini-loop feature is turned on, the detector cannot be used as a safety detector as there is no presence detection in this mode of operation. Contact Diablo Controls for more information on the mini-loop.

The DSP-19 can be used as either a safety loop or free exit loop detector. It also has the flexibility to be either “fail-safe” or “fail-secure”. It has a single solid-state open-drain FET output capable of sinking more than 250 milliamps.

The DSP-19 has 10 selectable sensitivity settings and uses a 6-position DIP switch to configure the detector. This includes the Diablo Controls mini-loop selection as well as sensitivity boost, extended presence and fail-safe/fail-secure operation. This makes the DSP-19 very flexible and versatile for those installations that need a little more than a standard detector.

Features

• Extremely low power. Less than 1ma of current draw in the non-detect state.
• Can be connected to a standard inductive loop as well as Diablo Controls freeexit probes.
• Single Solid State OpenDrain output that can sink over 250 milliamps.
• Front switch selectable Failsafe or Fail-secure operation.
• Wide operating voltage range with extended low-voltage operation.
• Sensitivity Boost for applications detecting semi-trucks.
• Extended Presence able to hold most calls for more than 12 hours.

LED Indicators: The green Power LED will be on blip on once every two seconds to indicate the detector is powered and operating normally in the low power mode. The LED will be on solid when there is possible activity over the loop. If the LED is not in one of these two modes, it is indicating a current or prior fault.

Failure Operation: In fail-safe, the detector will output a detect when the loop circuit is failed. In fail-secure, the detector will not output a detect when the loop circuit is failed. Set DIP switch 6 to off to operate in fail-safe mode. Set the switch to on to operate in fail-secure mode. Note: Never use a fail-secure detector for a safety loop.
