Wireless 4beam optical barrier JA-151IR

JA-151IR — Wireless 4‑beam IR optical barrier (Optex + Jablotron)

The JA-151IR combines Optex’s proven 4‑beam infrared optics with Jablotron wireless transmitters compatible with the JABLOTRON 100+ system. Detection is based on interruption of four IR beams between the transmitter and receiver, providing reliable detection of intrusions while reducing false alarms caused by small animals, falling leaves or similar disturbances.

The device is intended for outdoor installation and is designed to operate reliably in adverse weather conditions; the housing has an IP65 rating. Due to the precise optical alignment required for consistent operation, installation, alignment and final testing should be performed by a trained and certified installer.

Key specifications:

• Detection distance (transmitter to receiver): up to 100 m (environment dependent)
• Recommended mounting height: 0.7 – 1.0 m
• Wireless: 868.1 MHz, JA‑100 protocol
• RF range (open area): up to 300 m
• Power: 4x (8x) LSH20 lithium batteries (3.6 V / 13 Ah) — batteries not supplied
• Average battery life: approx. 3 years (approx. 6 years with 120 s energy‑saving mode)
• Enclosure protection: IP65; weight (receiver + transmitter): ≈ 3.3 kg
• Operating temperature: approx. −20 °C to +60 °C
• Occupies two addresses in the JABLOTRON 100 system

JA-151IR is suitable for securing external walkways, fence lines and access corridors where early detection is required with minimal false alarms. Prior to installation evaluate sight lines and potential IR interferences to ensure reliable operation.

Installer notes: perform alignment checks at multiple points along the protected span, verify wireless communication to the control panel and secure housings after final testing. Batteries and optional external antennae are supplied separately.
