## Summary description

Signal REC-105 is an optical receiver designed to accept and convert optical signals for integration into signaling and alarm systems. The REC-105 receives incoming optical inputs and outputs corresponding electrical signals for system processing. It is intended for use in security, fire alarm, or industrial signaling applications where optical-to-electrical signal conversion is required.

## Long description

Signal REC-105 is an optical receiver designed to accept optical inputs and convert them into corresponding electrical signals for integration with signaling and alarm systems. The device receives incoming optical signals and provides conditioned electrical outputs suitable for further processing by security panels, fire alarm controllers, or industrial monitoring equipment. Its compact form factor and straightforward electrical interface make it suitable for installations where reliable optical-to-electrical conversion is required.
Advantages
The REC-105 provides stable optical signal detection and reliable electrical output conversion without requiring complex configuration. Its design supports straightforward mounting and wiring in control cabinets or distribution boxes. The unit is compatible with common signaling and alarm architectures and minimizes the need for additional signal conditioning components. Built for continuous operation, it offers consistent performance in environments where optical signaling is used for event transmission.
Suitable for
 Security system integration for optical sensor inputs
 Fire alarm systems requiring optical-to-electrical conversion
 Industrial signaling and process monitoring installations
 Applications where optical links are used to transmit status or alarm conditions
Key specifications
 Function: optical-to-electrical signal conversion
 Input: optical signal receiver interface (fiber or optical emitter coupling)
 Output: electrical signal compatible with alarm and control panels
 Mounting: panel or DIN-rail compatible housing (compact)
 Operating conditions: designed for continuous indoor use within standard industrial temperature ranges
How to use
Install the REC-105 in a suitable enclosure or mounting location near the optical link termination. Connect the optical fiber or optical emitter to the receiver input according to the installation instructions supplied by the system integrator. Wire the electrical output terminals to the alarm or control panel inputs, observing correct polarity and any required common reference. Apply system power and verify reception by observing the controller’s input state or diagnostic indicators on the connected equipment. If needed, test the optical link with a known signal source before final commissioning.
Usage recommendations
Locate the receiver away from strong ambient light sources and secure optical connections to prevent signal loss. Ensure the enclosure provides adequate protection from dust and moisture for reliable long-term operation. Follow the integrating system’s electrical input requirements to avoid overvoltage or incorrect signal levels.
