Reed Switch with Tamper Circuit SATEL S-2 BR — Surface-Mount Brown

The SATEL S-2 BR is a surface-mount reed switch in brown with an integrated tamper circuit, designed for reliable detection of door and window openings and for monitoring the integrity of enclosures. The compact surface-mounted housing allows discreet installation on frames and casings where a visible, low-profile sensor is required. The device provides a normally closed reed contact for alarm signaling together with a tamper contact that signals cover removal or forced access to the sensor.

Advantages

This surface-mount reed switch combines magnetic contact sensing with an internal tamper circuit in a single unit, reducing the need for separate components. Its small brown housing is intended for visible mounting on wooden or painted surfaces where color matching matters. The integrated tamper improves overall system security by reporting attempts to remove or sabotage the sensor, while the reed contact offers reliable mechanical switching with low power consumption and a long service life.

Suitable for

• Monitoring doors and windows in indoor alarm systems
• Protecting electrical or communications enclosures and housings
• Retrofit installations where surface mounting is preferred
• Visible sensor applications where brown finish is desired

Key specifications

• Mounting type: surface-mount housing suitable for frame and enclosure surfaces
• Contact type: normally closed (reed) magnetic contact for open/close detection
• Tamper function: built-in tamper circuit to detect cover removal or forced access
• Intended use: indoor security and alarm systems
• Color: brown housing for discreet visible installation

How to use

Install the reed switch on the fixed frame and position the magnet on the moving sash or door so that the reed contact closes when the door or window is shut. Connect the reed contact and the tamper circuit to the alarm control panel according to the panel manufacturer’s wiring scheme, ensuring correct zone configuration for both the main contact and the tamper input. For surface mounting, use appropriate screws or adhesive recommended for the mounting surface, and verify that the magnet aligns with the switch across the full range of motion.

Usage recommendations

Place the sensor where it is protected from direct exposure to moisture and excessive mechanical stress. Verify alignment and operation after installation and test the tamper circuit periodically as part of routine system maintenance to ensure continued detection of unauthorized cover removal.
