Related: Alarm Detector

The Athenalarm AS-971 is a wired digital vibration detector that uses a piezoelectric vibration sensing principle to identify physical impact, knocking, and other vibration events on protected objects and surfaces. Adjustable sensitivity and cumulative vibration detection allow the AS-971 to be configured for a range of intrusion-security applications, including ATMs, cash vaults, safes, and jewelry stores.

The detector can trigger an alarm from either a single strong vibration or several accumulated slight vibrations. Its NC alarm output and independent tamper output support integration with compatible wired intrusion alarm control panels.

Key Applications

• ATM security
• Cash vault protection
• Safe and high-value asset protection
• Jewelry store security
• Surface-mounted intrusion detection
• Commercial security projects

Key Technical Advantages

• Piezoelectric vibration sensing
• Adjustable sensitivity (potentiometer + high-sensitivity jumper)
• Single strong-vibration alarm triggering
• Cumulative detection of slight vibrations
• NC alarm output for control-panel integration
• Independent tamper output
• Compact 85 × 26 × 32 mm housing

1. Quick Procurement Facts

2. Product Overview

AS-971 Digital Vibration Detector for Physical Security Applications

The AS-971 is designed for security applications where unauthorized knocking, hitting, drilling, or other physical disturbance of a protected object may indicate an attempted intrusion.

Its piezoelectric sensing element detects vibration transmitted through the protected surface. Sensitivity can be adjusted according to the installation environment, allowing installers to configure the detector to the required detection conditions and reduce false alarms.

The detector responds to:

• A single large vibration, or
• Several accumulated slight vibrations

This dual detection behavior makes the AS-971 suitable for applications where repeated low-level impacts — such as attempted drilling or prying — may need to be recognized as an alarm condition, in addition to a single high-force impact.

The detector is installed directly onto the surface of the protected object. Target applications for this detector include ATMs, cash vaults, and jewelry stores.

3. Key Technical Features

3.1 Piezoelectric Vibration Sensing

The AS-971 uses a piezoelectric sensing principle to detect vibration transmitted through the protected surface, making it suitable for physical-security applications where impact-generated vibration must be identified.

3.2 Adjustable Sensitivity

Sensitivity is adjusted using an onboard potentiometer. Installation procedure begins at the lowest sensitivity setting, increasing gradually while testing the protected object. A high-sensitivity jumper (S1) is available when a higher sensitivity setting is required.

3.3 Cumulative Vibration Detection

The detector can accumulate slight vibrations and trigger an alarm once the configured detection threshold is reached, rather than relying only on a single large impact.

3.4 Tamper Protection

A dedicated tamper terminal provides an anti-tamper output for integration with a compatible alarm control system.

3.5 NC Alarm Output

The alarm output is normally closed (NC), supporting connection to compatible wired intrusion alarm control panels.

3.6 Compact Housing

Dimensions of 85 × 26 × 32 mm provide a slim form factor suited to installation on protected objects with limited mounting space.

4. Applications

4.1 ATM Security

The AS-971 can be installed on an ATM or related protected surface to detect vibration associated with physical attacks such as knocking or hitting. Actual detection performance should be evaluated according to ATM construction, mounting location, and sensitivity setting.

4.2 Cash Vault Protection

The detector can be surface-mounted on suitable vault structures to detect vibration transmitted through the protected structure. Cumulative vibration detection is relevant where repeated slight impacts form part of the attack scenario.

4.3 Safe and High-Value Asset Protection

The AS-971 can be installed directly onto a suitable safe or protected metal surface where vibration detection is required.

4.4 Jewelry Store Security

The detector can be used as part of a physical-security system protecting high-value assets or suitable structures within jewelry-store environments.

4.5 Other Suitable Protected Surfaces

The detector may be considered for other applications requiring wired, surface-mounted vibration-based intrusion detection. Final suitability depends on the protected material, mounting method, environmental conditions, and required detection performance.

5. Detection Range by Surface Material

Important: These figures represent reference detection radii, not a guaranteed coverage specification. Actual detection performance can be affected by:

• Surface construction and material characteristics
• Mounting quality and mechanical contact
• Vibration transmission through the structure
• Installation position
• Sensitivity setting
• Environmental conditions

6. Technical Specifications

7. Alarm & Control-Panel Integration

The AS-971 is a wired detector providing:

• 9–16 VDC power input
• NC alarm output
• Independent tamper output

The NC alarm output is compatible with alarm control panels. Before deployment, installers should verify that the selected control panel supports the detector’s electrical characteristics and NC contact configuration, including the maximum switching voltage/current shown in Section 6.

Terminal Connections

8. Installation & Sensitivity Adjustment

The AS-971 is designed to be fixed directly onto the protected object or surface, in any direction.

Installation Guidance

• Choose a mounting location where the detector can reliably receive vibration signals from the protected area.
• Fasten the detector securely to the protected object using screws.
• Do not use adhesive tape as the mounting method — secure mechanical contact is required for reliable vibration transmission.

Sensitivity Adjustment Procedure

1. Turn the sensitivity potentiometer fully counterclockwise and keep jumper S1 off to establish the lowest sensitivity.
2. Gradually rotate the potentiometer clockwise to increase sensitivity.
3. Knock the protected object and observe the alarm indicator LED.
4. Confirm the detector responds correctly to the intended vibration level.
5. If higher sensitivity is required, set jumper S1 to the high-sensitivity position.

The final sensitivity setting should be determined according to the specific protected object and installation environment.
