Product information

Description

The UBIQUITI USL-Entry is a compact wireless door and window sensor that monitors open/closed status. It operates on the 865.1–869.5 MHz and 915.6–927.6 MHz bands and is powered by a CR123A lithium battery designed to last up to 72 months. The sensor provides reliable contact sensing for entry monitoring and integration with security or smart building systems in locations where a small, long-life wireless device is required.

Advantages

The sensor offers long battery life of up to six years and wireless connectivity on regional sub‑GHz bands for extended range and low power consumption. Its compact white housing is unobtrusive on doors and windows and is suitable for integration with alarm systems and automation platforms that accept contact sensors.

Suitable for

  • Home and small office door and window monitoring
  • Security system contact inputs and alarm zones
  • Smart building installations requiring low‑maintenance sensors

When it may not be suitable

This sensor uses sub‑GHz wireless bands specific to certain regions; it may not be compatible with systems that operate on different frequencies or proprietary protocols. It is a contact sensor only and does not include motion detection, environmental sensing, or wired connectivity.

Key specifications

  • Wireless connectivity on 865.1–869.5 MHz and 915.6–927.6 MHz bands
  • Power source: CR123A lithium battery
  • Estimated battery life: up to 72 months (typical use)
  • Form factor: compact door/window contact sensor
  • Colour: white

How to use

Mount the sensor and its magnet on the door or window and frame so that the two parts align when closed. Install a CR123A battery following polarity markings, pair the sensor with your compatible gateway or controller according to the gateway’s pairing procedure, and configure the sensor’s contact input within your security or automation system to generate open/close events and alarms as required.

What to consider before purchase

  • Ensure the sensor’s wireless frequency bands (865.1–869.5 MHz or 915.6–927.6 MHz) match regional regulations and your gateway’s supported frequencies.
  • Verify your security or automation controller supports external contact sensors and the pairing protocol used by the device.
  • Confirm mounting surface and alignment space on the chosen door or window for correct sensor operation.

Usage recommendations

For reliable operation, place the sensor and magnet with minimal gap when the door or window is closed, test signal strength at the intended mounting location, and replace the CR123A battery before the end of its expected life to avoid missed events.
