Lekley Outdoor Professional Detector Technical Specifications

RK315DT Captures Performance and Avoids False Positives
Outdoor professional detectors should include both PIR and microwave technology. The detection range should be 15m 90°. A telephoto lens should be provided in the product package for 23m 5° and barrier 15m 5°.
Outdoor detectors should use 2 PIR channels with digital correlation technology and 2 microwave channels with shaking recognition technology for reliable capture performance and avoid false alarms for all of the following reasons:

Because the strong wind or clouds/solar conditions change, combining different temperatures of heating and cooling with different materials causes the background temperature to change rapidly. Rain, hail, and snow reflections Move and shake objects, such as bushes, leaves, and moving objects Scraping debris Pets and animal heads up to 70cm

Standards <br> Outdoor detectors shall comply with EN-50131 Safety Class 3 and Environmental Class III. The product should meet all the requirements set out by the R&TTE Directive for its type. The detector should have a CE mark.

Installation Flexibility <br> Detector installation height is between 1 and 2.7m.
The detector should be provided with a dedicated professional rotating bracket with a vandal-proof concealed wiring and wall tamper, as follows:

Standard swivel bracket - supplied as standard with the detector. Pillar mounting brackets – for mounting on poles (optional). Barrier swivel bracket – for 90° mounting to mounting surface (optional). Catheter Bracket – Used for installation of conductors in conduits outside walls or posts (optional). Rotary Catheter - Used with a standard swivel bracket when the wire is inside a duct outside the wall (optional).

Microwave anti-collision function <br> Outdoor detectors should have microwave anti-collision function, can install DT detectors in the vicinity or even face to face.

Anti-Mask <br> The detector should use 4 active IR channels to continuously monitor the masking intention of the lens. The AM signal should be provided through a separate relay output (also showing any fault in the detector) or via a 4-wire bus installed on the ProSYS bus.

Dirty lens reminder
The detector should have a “dirty lens” reminder function that can be alerted via a separate output port when the detector lens needs cleaning. The active IR channel used for the anti-mask will also constantly check the transparency of the lens, but use different methods of determination. The "dirty lens" alert will be provided via a separate 70mA open collector output port on the terminal module or via the ProSYS bus.

Environmental Ratings <br> The environmental rating of the detectors should be IP65. Used to protect the detector from horizontal spray.

Protective cover <br> The detector should have an integrated protective cover to protect against sunlight, rain, hail, snow, dust and bird droppings.

Walk test LED
The detector should have 3 high-visibility LEDs to support the detector walk test in outdoor light conditions.
Remote control and diagnostics (when installed on ProSYS bus) When installed on a 4-wire ProSYS bus, the detector should have remote control diagnostics. This will provide:

Faster, more cost-effective installation: Wiring requirements in relay mode Each detector's wiring is directly connected to the panel (star configuration only). Through the bus wiring, the detectors can be linked between them, saving a lot of wiring time and shortening the installation time. Fewer wires and easier installation: In bus mode, only 4 wires are required for all installations. In repeater mode, up to 10 wires may be required to implement the full functionality of the detector: Basic installation of alarms and tamper devices requires 4 wires and AM output port requires 2 wires. The use of support LEDs, set/cancel setting controls, remote test controls, and functions for "dirty lens" reminders require additional cabling connections. Remote diagnosis: The remote diagnosis function saves on-site visits according to the requirements of the contractor. If on-site maintenance is required, the contractor can know the exact nature of the problem in advance, thereby saving time and effort on site. The remote diagnostics function is:
The voltage input to the detector is measured. Measure the signal and noise levels from the detector's 4 channels. Software version.

Remote Control: All settings of the detector should be adjusted from the ProSYS keyboard or via upload/download software, saving installation and adjustment time. In addition, the detection sensitivity setting can be changed to avoid false alarm issues until the contractor can access the site. Remote control settings should include:

LED Control: 3 LED / 1 LED / Off Detection Sensitivity: (Low, Medium, Normal, High). High detection sensitivity will disable the shake recognition MW range: minimum, 20%, 40%, 60%, 80%, maximum (maximum 23m), trimmer (MW range is defined by the trimmer on the PCB) alarm logic: and / or (For OR logic, probes in the MW or PIR channel will trigger an alarm.) Lens type: Wide/telephoto (used to synchronize the detector's processor settings with the mounted lens) Anti-mask: On/ Off Follow Arming: On/Off

Camera options <br> Outdoor detectors should have the option to include a built-in camera in the same housing and use a 4-wire camera connection separate from the detector. The camera should contain an optical lens.
