GRMS Control Panel

The room control panel is a one box solution, fully wired and ready for installation. There are different control panel solutions on offer, sizable to centralised, distributed or hybrid controls. Cabling topology for centralised control requires all field 230V and control cables to be wired into the panel.

 Distributed controls have a minimal amount of wires into the panel and require the least panel space, reducing cabling costs substantially. Further, contraction and expansion of the system may have little impact on the size of the distributed panel. 

Through the RON bus communication, the Local Control Unit (LCU) is connected to output devices such as relays, dimmers and PWM/0-10Vdc analogue outputs.

 The control panel with its configurable application software, is a smart control system, suitable for hotels, homes, apartments and other residential or commercial buildings. It can operate as a stand-alone system or as part of a network of control cabinets using TCP/ IP communication protocol.

The room control panel is assembled in an all metal enclosure made in accordance to BS7671:2008 standard, incorporating amendment 3:2015. It is designed and assembled for easy and accurate connections of field wires to it by a skilled installer. Each of the one panel solutions can easily be configured with a laptop or Android tablet by the installer, who can configure controller functionalities on site. This can eliminate visits from the manufacturer for commission or configuration purposes.


Diverse range of control panels available with different combinations of relay outputs, Triac leading edge or MOSFET trailing dimmer and PWM/0-10Vdc controls, as per requirements

Centralised Control.  Each control panels can be scaled to a larger system by linking multiple GRMS panels together or a making a custom made larger enclosure, supporting up to a maximum number of 92 channels per system

Scalable from a stand-alone systems to a large network, using TCP/IP communication link

Supports up to 24 switch plates of up to 4 buttons each, providing a maximum of 96 individual button control

Each button on each switch plate can be programmed to control one or many (as a group) of the 118 channels and outputs

Supports mobile devices through external wireless network

Supports 8 low level inputs and 4 low level outputs for devices such as PIR and door contacts

RON bus for interface to peripheral control and telemetry devices (wall switch plates, sensors, relays, mains dimmers and 0-10V dimming)
