Monarch MCTC-SCB-D Elevator Pre-open Door Control Board Safety PCB For NICE3000 System

Monarch MCTC-SCB-D Elevator Pre-open Door Control Board Safety PCB For NICE3000 System

MCTC-SCB-D is a safety control expansion board for Monarch NICE3000 elevator controller, mainly used for door pre-opening and UCMP protection monitoring. It reliably executes safety relay output, detects door zone signals and prevents unintended car movement. Stable signal transmission, strong anti-interference, easy wiring and installation. Ideal replacement for elevator maintenance and renovation.

Seloon elevator push button A4J18481 is a widely adopted square call button designed for elevator LOP hall panels and COP car operating panels, offering excellent compatibility with Seloon, Diao, BST and Jiangnan Jiajie elevator systems. Built with brushed stainless steel faceplate, it resists scratches, fingerprints and daily abrasion, maintaining a neat appearance even under heavy, frequent use in residential buildings, commercial plazas, hotels and office towers. Each button is equipped with standard Braille symbols, complying with accessibility requirements and bringing convenience for visually impaired passengers.

Powered by DC24V low-voltage LED backlight, it supports multiple light color options including red, blue and white. The soft and uniform backlight clearly indicates call status, easy to identify in dim corridors or dark cabins. High-quality built-in micro-switch delivers crisp, sensitive tactile feedback and ultra-long service life, capable of enduring millions of press cycles without sticking, delay or signal failure. The integrated PCB module adopts stable circuit design with good moisture-proof and anti-corrosion performance, which can work reliably in environments with temperature and humidity fluctuations.

It features a standard square outline and plug-in connector structure, making on-site installation, replacement and wiring fast and straightforward without complicated modification. Every piece undergoes strict lighting and signal function inspection before delivery to eliminate common defects such as dim light, no response and intermittent signal loss. As a cost-effective replacement spare part, it is ideal for routine elevator maintenance, control panel refurbishment and elevator modernization, helping you quickly restore normal elevator call functions, reduce passenger complaints and upgrade the overall riding experience.
