Optical Tamper Detector SATEL SPL-TO — SATEL optical sabotage/tamper sensor SPL-TO

SATEL SPL-TO is an optical tamper detector designed to identify physical interference with security devices and enclosures. The sensor monitors attempts to open, move or otherwise manipulate protected equipment and generates a tamper alarm output to the security control system. Intended for use in alarm and access-control installations, the SPL-TO provides an optical method to detect sabotage of cabinets, control panels and other housings containing electronic security components.

Advantages

The optical tamper detector offers non-contact sensing that reduces wear and mechanical failure compared with mechanical tamper switches. Its optical detection method provides rapid response to movements, cover openings or masking attempts. The detector is compact and suitable for integration into cabinets and panels, allowing straightforward connection to standard alarm control inputs. Designed for reliable operation, the device supports continuous monitoring of enclosures without affecting the protected equipment.

Suitable for

• Monitoring cabinet and enclosure doors in alarm systems
• Protecting control panels and access-control units from tampering
• Securing housed sensors, power supplies and communication modules
• Use inside server racks, switch cabinets and equipment cabinets

Key specifications

• Detection method: optical tamper sensing
• Function: detects movement, opening or manipulation of enclosures
• Output: tamper alarm signal compatible with alarm control inputs
• Form factor: compact sensor designed for installation inside cabinets and housings
• Operating application: indoor enclosure protection in alarm and access-control systems

How to use

Install the optical tamper detector inside the enclosure or on the cover where it has a clear line for detecting movement or opening events. Connect the device output to the designated tamper or auxiliary input of the alarm control panel according to the system wiring standards. Adjust mounting position so the sensor reliably detects the expected range of cover travel or displacement without interference from internal equipment. Test the detector after installation to confirm it registers tamper conditions and communicates correctly with the control system.

Usage recommendations

Position the sensor to avoid direct exposure to intense light sources or reflective surfaces that may affect optical detection. When installing in cabinets with many internal components, verify that normal maintenance actions do not generate false tamper signals; route wiring and components to minimize unintended movement near the sensor. Follow the alarm system manufacturer’s guidelines for input type and alarm configuration to ensure proper integration.
