Overview
Central controlled fire emergency indicating luminaire powered by centralized battery. Model: SJ-BLJC-Ⅱ1LE3WB2.

Product features

• Can be controlled and powered via two-bus non-polar signal to reduce installation costs.
• Green LED light source for lower consumption and long service life; modular replacement.
• Driven by constant-current source to ensure stable lumen output.
• Resistant to high temperature and corrosion; suitable for most indoor industrial environments.

Product Info

• DC24V safety voltage supply.
• Built-in CPU with unique coding; monitors and reports lamp communication faults, optical circuit faults and operating status.
• High-luminance green LED: low power, long lifetime, good penetrating light and uniform brightness.
• Connection: four-wire bus (RS485 signal bus + DC24V power) to the host; installation is straightforward and reliable.
• No local battery set required; system-powered for energy saving and simplified maintenance.
• Light source details:
  • Sampling Φ3 LED super bright green, model HH-H52WC-S.
  • If light source fault is confirmed, replace the LED module by removing the LED plate.
• Maintenance: every two months switch off controller main power and verify lamp operation; if lamp fails, check wiring and LED module.
• Illumination: 1.0 Lx, suitable for various locations.
