Contact Closure Control

While they provide a physical control interface, LynTec switches are engineered system components that offer more than a basic contact closure. They are designed for seamless integration with our power sequencers, providing a reliable and dedicated point of control.

Features can include key-lock security, clear LED status indicators for sequence operation, and simplified wiring schemes. For instance, the RC5-WM uses a single RJ-45 cable for signal and power, making installation faster and more robust than wiring a generic switch to a terminal block.

Absolutely. Contact closure provides a robust, hardwired control layer that operates independently of an IP network, DMX, or sACN controller. This makes it an excellent failsafe or backup control method.

An integrator can configure a system where a physical switch provides a manual override in case of network failure, ensuring that essential systems can always be controlled. It can also be used for local control in a room while still allowing for centralized network management of the entire facility.

Yes, our intelligent panels are designed for multi-protocol environments. Products like the RPC, LCP, and NPAC can respond to DMX, sACN, IP (Telnet/HTTP), and dry contact closure inputs simultaneously. This allows for a layered control strategy. For example, you can use DMX for show-specific cues from a lighting console, an IP-based system for building automation, and a contact closure for a simple wall switch or fire alarm integration, all on the same panel.

Yes, this is a critical safety integration we support. The RC-DM3 Remote Control Combiner includes a dedicated contact terminal for connecting to a normally open (N.O.) fire alarm trigger.

When the alarm system closes the contact, the RC-DM3 sends a forced sequence-down command to the connected CQ Series sequencer. This ensures all sensitive audio, video, and lighting equipment is powered down in an orderly and safe manner during an emergency.

Yes. A single contact closure event, like turning a key switch or pressing a button, can initiate a complete, pre-programmed power-on or power-off sequence. This allows for simple ‘one-touch’ control of an entire AV or lighting system from a lectern, wall plate, or other convenient location.

Products like the RPC, NPAC, and CQ Series all support sequence initiation via contact closure, simplifying system operation for end-users while ensuring equipment is powered on and off safely.

Yes, integration with emergency systems is possible using the RC-DM3 combiner. It includes a dedicated terminal for a normally open (N.O.) dry contact, which can be connected to a fire alarm or other life safety system. When this contact is triggered, the RC-DM3 forces an automated, orderly power-down sequence for all connected equipment, enhancing venue safety.

Each standalone unit has a built-in web server for initial setup, sequencing configuration, and direct control. For daily operation, they can be triggered by a simple contact closure from a wall switch or sensor. Many units also accept commands via IP or DMX, providing flexible control options for any environment.

The Emergency Power Off (EPO) port is a safety feature that allows for immediate, remote shutdown of the UPS. An integrator can connect this port to a centralized emergency stop button or a fire alarm control panel.

When the external switch is activated, it signals the SRA to instantly cut power to all its output receptacles. This is a critical function for complying with safety protocols in many venues and installations.

Our switches are designed for simple, reliable integration. They connect to dedicated low-voltage inputs on LynTec power control panels like the RPC, RPCR, and NPAC series. This direct connection uses standard low-voltage wiring, making installation straightforward for any qualified installer.

This design ensures the switch acts as a dependable local interface for the panel’s intelligent sequencing and control logic, providing a physical trigger for pre-programmed power up or power down sequences.

LynTec panels are designed to prioritize life-safety and manual inputs. A contact closure input, typically connected to a fire alarm system, can be configured to override any network-based commands to ensure emergency systems activate correctly. This is a key feature for our UL 924 listed RPC and LCP panels. The web interface allows you to define the priority and behavior of these physical inputs, ensuring safe and predictable operation.

Our accessories include specialized connectors and wiring harnesses designed to streamline connections between LynTec panels and third-party control systems. By providing the correct components, we reduce the time spent on terminal wiring and minimize potential points of failure. This helps ensure reliable communication for protocols like DMX, sACN, or simple contact closure.

For life safety applications, a contact closure input on a LynTec panel is wired directly to a relay output on the building’s Fire Alarm Control Panel (FACP). When the FACP enters an alarm state, it closes the relay, sending a signal to the LynTec panel.

This signal overrides all other control commands and forces designated emergency circuits, such as egress lighting, to an ‘on’ state. This direct, hardwired connection ensures reliable activation and is a key component for meeting UL 924 standards for emergency lighting control.

The CQ ecosystem supports emergency shutdown integration through a normally open (N.O.) dry contact closure. Accessories like the RC-DM3 Remote Control Combiner include a dedicated terminal for connecting to an alarm panel. When the alarm contact is closed, the system initiates an automated and orderly power-down sequence for all connected equipment, enhancing facility safety.

MS panels feature an integrated emergency shutdown function for life safety integration. This is managed via a dry contact closure input that connects directly to a fire alarm or other emergency system. When the contact is triggered, the panel immediately powers down all sequenced circuits in a single step, ensuring the system is safely de-energized during an emergency event as required by many local codes.

The PDS series is designed for straightforward integration. Sequencing is initiated via a simple, low-voltage dry contact closure from an external key switch, a control system relay, or another master power control panel. This allows for easy implementation into a wide range of system designs without requiring network access or complex programming.

The SQ Series is controlled via a simple contact closure input. This allows for straightforward remote activation of the power up and power down sequences.

You can trigger the unit using a basic momentary wall switch, a key switch, or a relay output from any third-party control system like Crestron, AMX, or Q-SYS. This design ensures reliable operation without needing a network connection or complex programming.

The MS series is designed for simple, reliable control. The sequence is typically initiated by a low-voltage, momentary key switch or other dry contact closure. This provides a straightforward one-touch start and stop for the entire system, making it easy for any operator to use safely and preventing accidental operation.

A momentary contact sends a brief, temporary signal, like a single press of a push button. This is typically used to trigger an action, such as starting a power-up sequence or toggling a zone’s state.

A maintained contact holds its state (either open or closed) until it is physically changed, like a light switch or a key switch. This is often used when the power system should directly mirror the state of the switch. For example, if the key is in the ‘on’ position, the system is on. LynTec controllers can typically be configured to respond to either input type depending on the application’s needs.

Any device capable of providing a dry contact closure (a relay) can trigger an RT Series module. Common examples include fire alarm control panels for emergency power-off (EPO) functions, simple key or toggle switches for manual override, motion sensors for automated activation, or the relay outputs from a third-party control system.

The RT Series is activated by a low-voltage, dry contact closure. This allows for simple and reliable control from any device that can provide a relay output, such as an alarm panel, a simple wall switch, or a third-party control system. The connection is made using a clearly labeled terminal block for fast, trouble-free installation.

LynTec panels can be triggered by any device that provides a simple dry contact closure signal. This includes common physical controls like momentary push buttons, maintained key switches, and toggle switches. It also allows for integration with automated systems such as occupancy sensors, projection screen limit switches, and third-party control or building automation systems.

This versatility makes contact closure an ideal method for providing simple, direct, and reliable local control over power circuits or sequences.

The RT Series is engineered for applications where direct, non-networked control is required for maximum reliability. Choose the RT Series when you need to integrate with systems like life safety alarms, simple key switches, or basic control panels that provide a relay output.

It is the ideal solution when network access is unavailable, unreliable, or when advanced monitoring and remote management are not required for the equipment being controlled.

The LynTec RPC Remote Control Breaker Panel and LCP Lighting Control Panelboard series are specifically engineered with dedicated, supervised contact closure inputs for fire alarm integration. These inputs are designed to connect directly to a Fire Alarm Control Panel (FACP) to meet life safety code requirements for emergency lighting control, including UL 924.

This built-in functionality simplifies the design and installation of code-compliant emergency power systems for performance venues and public spaces.
