Altronix TS112 Plunger Tamper Switch

The Altronix TS112 is a mechanical plunger-activated tamper switch designed to detect unauthorized access to equipment cabinets, enclosures, and access panels in security installations. When a cabinet door or access point is opened, the plunger depresses and triggers a relay output that integrates directly with your security alarm system or monitoring panel. This accessory provides a straightforward, passive detection method that requires no power source and works independently of network connectivity—meaning cabinet intrusion can be logged and alarmed even if your IP infrastructure is offline.

Key Features

• Plunger-activated mechanical design — Physical contact triggers the switch instantly; no electronic logic or batteries to fail. Reliable for repetitive tamper cycles over the product lifetime.
• Relay output for alarm integration — Connects directly to security control panels, BMS inputs, or custom alarm circuits. The relay contact closure alerts you to unauthorized enclosure access without network dependency.
• Pre-mounted bracket included — Ships with installation bracket hardware, reducing mounting labor on cabinet frames, door hinges, or panel edges. Compact footprint fits tight spaces where larger switches won't fit.
• Robust mechanical construction — Designed for repeated actuation cycles typical of high-traffic equipment rooms or test facilities. Metal housing and stainless components resist corrosion in humid or dusty environments.
• Compact form factor — Small profile allows installation on doors, drawers, or hinged access panels without interfering with cabinet operation or aesthetics.
• Lifetime Limited Warranty — Altronix backs the TS112 with a lifetime limited warranty, reducing replacement costs over extended deployments.

Integration & Compatibility

The TS112 integrates with any security system that accepts dry-contact relay inputs—standard practice across intrusion panels, access control systems, and building management platforms. No proprietary software, drivers, or network configuration required. Install the switch, wire the relay contacts to your panel input, and configure an alarm rule. The mechanical nature of the design means it works with legacy systems and modern platforms equally well.

Typical Applications

• Equipment cabinet and server enclosure door monitoring in data centers and telecom facilities.
• Access panel protection on wall-mounted security equipment, power distribution units, or network infrastructure.
• Intrusion detection for battery backup cabinets, UPS enclosures, or other critical infrastructure.
• Integration into facility-wide alarm systems where cabinet tampering must trigger central alerts.

When to Choose a Different Configuration

If you require wireless transmission of tamper events or IP-based logging without wiring to a central panel, consider a network-connected cabinet sensor or a wireless transmitter module paired with a tamper switch. If your application involves frequent, rapid-cycle opening (as in high-volume access scenarios), verify the switch cycle rating with manufacturer specifications. For extreme temperature or chemical environments, consult the datasheet to confirm material compatibility before deployment.

Frequently Asked Questions

Q: Does the TS112 require power?

A: No. The TS112 is a passive mechanical switch that operates via physical contact. It requires no batteries, power supply, or network connection—only a wired connection to your alarm panel or control input.

Q: What type of relay output does the TS112 provide?

A: The TS112 offers a dry-contact relay output, meaning it closes a circuit when the plunger is depressed. This relay contact can be wired directly into security panels, access control systems, or any device with a standard alarm input.

Q: Can I use the TS112 on a hinged cabinet door?

A: Yes. The TS112 is designed for cabinet and door monitoring. Mount the switch body to the frame and the plunger to the door so that opening the door compresses the plunger and triggers the relay. The pre-mounted bracket simplifies this installation.

Q: What is the lifetime limited warranty?

A: Altronix provides a lifetime limited warranty on the TS112. Exact terms and coverage details are available in the manufacturer warranty documentation.

Q: How many switch cycles can the TS112 handle?

A: The TS112 is engineered for repeated actuation typical of cabinet door monitoring. For specific cycle-life ratings or durability in high-frequency-access environments, consult the product datasheet or contact the manufacturer.

Q: Does the TS112 work with modern security control panels?

A: Yes. The TS112's dry-contact relay output is compatible with any security panel, access control system, or BMS that accepts standard relay inputs—both legacy and contemporary platforms.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The Altronix TS112 is a deliberate choice for facilities that prioritize mechanical simplicity and alarm reliability over IoT connectivity. It's an accessory I recommend when cabinet tamper detection must work independently—that is, when your security panel needs to alarm a door breach even if your network infrastructure is down or overloaded.

Technical Highlights:

• Passive mechanical operation: No power, no batteries, no firmware failures. A plunger touch triggers a dry-contact relay every time. That reliability matters in data centers where uptime is non-negotiable and you can't afford a wireless sensor to drop off the mesh.
• Dry-contact relay integration: Wires directly to any panel input—legacy or modern. You're not locked into vendor-specific protocols or cloud dependencies. The relay is simple enough that even analog alarm control systems can monitor it.
• Compact mounting bracket: Pre-installed hardware cuts installation time. The form factor is small enough to fit cabinet hinges and access panel edges without cramping your layout.
• Lifetime limited warranty: Altronix stands behind this switch with a no-expiration warranty, reducing lifecycle costs on long-term cabinet protection strategies.

Deployment Considerations:

• Wired installation only: The TS112 requires a hardwired connection to your alarm panel. If your cabinet is mobile, remotely located, or you need wireless transmission, a wireless tamper module or IP-connected sensor is better.
• Plunger alignment matters: Installation success depends on accurate mounting so the plunger sits at the right depth. If the plunger is too proud or recessed, the switch may not actuate reliably. Test actuation before commissioning.
• High-cycle durability: The TS112 is rated for repeated actuation, but in environments with very frequent door access (e.g., server hot-swap bays), verify cycle-life expectations before rolling out to hundreds of cabinets.

Deploy the TS112 in multi-site data centers, telecom equipment rooms, and secure server facilities where you need passive, wired, network-independent cabinet intrusion detection and you can tolerate the labor of running alarm circuits to each cabinet.
