The Ascom Corridor Lamp 4 (NICL4) is a peripheral device designed to provide visual indications within a healthcare or similar environment, controlled by a room controller (specifically the NIRC4). Each room bus of the NIRC4 room controller can support up to four NICL4 corridor lamps, offering flexibility in system design and coverage.
Function Description:
The primary function of the NICL4 is to display visual signals using LED boards. It supports up to four LED boards, which can be either NILD2 (single color) or NILD4-RGB (multi-color), positioned behind a translucent dome cover. These LED boards are not included with the NICL4 and must be ordered separately. The specific color and position of the LED indications are determined during the system setup, allowing for customizable visual alerts based on the needs of the facility.
The NICL4 connects to the room bus using an RJ45 cable, adhering to the Ethernet T-568B color coding standard. It features two RJ45 room bus connectors, enabling daisy chaining with other NU-series peripheral devices (PDs). This daisy-chaining capability simplifies wiring and installation in multi-device setups. Power for the corridor lamp (5.5VDC) is supplied through the room bus connection, eliminating the need for separate power sources for each lamp.
A buzzer is also integrated into the NICL4, providing an audible alert in addition to the visual indications. The device includes DIP switches for selecting the Corridor Lamp ID, allowing for unique identification and control of up to four lamps on a single room bus.
Important Technical Specifications:
- Ingress Protection: IP40, indicating protection against solid objects larger than 1mm, but no protection against liquids. This necessitates installation in clean, dry, and weatherproof areas.
- Power Input: 5.5VDC, supplied via the room bus connection.
- LED Board Support: Up to 4 NILD2 (single color) or NILD4-RGB (multi-color) LED boards.
- Connectivity: Two RJ45 room bus connectors for Ethernet T-568B standard cabling, supporting daisy chaining.
- Room Controller Compatibility: Specifically designed to be controlled by the NIRC4 room controller.
- Corridor Lamp ID Selection: DIP switches allow for selection of IDs from 0 to 3, accommodating up to four NICL4s per room bus.
Usage Features:
- Customizable Visual Alerts: Supports both single-color and multi-color LED boards, allowing for a wide range of visual indications to convey different types of alerts or statuses. The position and color of the LEDs are configurable during system setup.
- Audible Alerts: Includes a buzzer for audible notifications, complementing the visual cues and ensuring alerts are noticed even when visual attention is elsewhere.
- Daisy Chaining: Two RJ45 connectors facilitate easy daisy chaining with other NU-series peripheral devices, simplifying network topology and reducing cable runs.
- Flexible Mounting: The base of the NICL4 is designed for versatile mounting options. It can be mounted onto various EU and North American-style backboxes, or directly onto flat wall surfaces where backboxes are not available.
- Cable Management: Features knockouts at the bottom or right side of the base for cable entry and exit, allowing for neat and organized wiring.
- Easy RJ45 Connector Compatibility: While not included, the system is designed to work with Easy RJ45 connectors, which simplify termination by allowing excess wire length to pass through and be automatically cut during crimping.
Maintenance Features:
- Installation Guide: Comprehensive instructions are provided for installation, including mounting procedures for different wall types and backboxes, as well as details on connecting LED boards and RJ45 cables.
- DIP Switch Settings: Clear guidance on setting the Corridor Lamp ID using DIP switches, which is a crucial step before connecting the PCB to its base.
- LED Board Placement: Specific instructions for inserting LED boards, emphasizing the importance of aligning pins with guide marks on the corridor lamp PCB to ensure proper connection.
- Safety Information: Important safety warnings are highlighted throughout the manual, including precautions regarding bright LEDs and the necessity of regular inspection and cleaning to prevent dust buildup, especially in clinical areas.
- Firm Mounting Requirement: The device must be firmly attached to the background to ensure the dome cover fits properly and does not fall off, which is a key aspect of long-term stability and safety.
- Cable Termination Guidance: Detailed information on terminating RJ45 connectors using the Ethernet T-568B color scheme, ensuring correct wiring for reliable communication.
- Knockout Removal: Instructions for carefully removing excess plastic from knockouts using a cutter or pliers, facilitating proper cable routing.
The NICL4 is designed to be a reliable and flexible component in a comprehensive communication and alert system, providing clear visual and audible indications in environments where timely information is critical. Its robust design and detailed installation instructions aim to ensure a safe and efficient setup.
