AKCP Dry Contact Sensor

In critical infrastructures such as data centers, industrial plants, or building management systems, dry contacts play a crucial role. The AKCP Dry Contact Sensor is designed for reliable, SNMP-enabled monitoring of these signals. Combined with AKCP’s sensorProbe and securityProbe platforms, it delivers TCP/IP-based real-time supervision of relay, alarm, and status contacts—flexible, stable, and robust.

High-Performance Technology and Durable Design

The Dry Contact Sensor monitors both open and closed states using a 5 V pull-up threshold. With a switch current capacity up to 20 mA (“low”), it supports practical monitoring scenarios. Multiple readings per second ensure that status changes are detected and reported immediately.

• Contact type: pull-up dry contact, 5 V
• Measurement frequency: multiple readings per second
• Output current: up to 20 mA at “low”
• Cable range: up to 305 m over Cat5/6
• Connector: RJ-45, compatible with AKCP systems
• Power: supplied directly by base unit
• Construction: compact, durable, low-maintenance

Installation with AutoSense

With AutoSense technology, dry contact sensors are automatically recognized by AKCP systems upon connection. Configuration is plug-and-play via the base station web interface, minimizing installation effort and ensuring seamless integration into existing monitoring setups.

Alarm and Notification Options

When the contact state changes (open/closed), the monitoring system can trigger:

• Email notifications
• SMS/MMS alerts via GSM/LTE
• SNMP traps to central NMS
• Immediate activation of relays or emergency systems

Integration with software platforms such as Nagios, PRTG, Zabbix, IBM Tivoli, WhatsUp Gold, and OpenNMS is fully supported.

Versatile Application Scenarios

• UPS systems: battery state and equipment status
• Generators and backup power: fault or operational alerts
• HVAC: fault signaling and system status
• Fire protection: linking to smoke detectors and RWA contacts
• Building management: door contacts, relay feedback
• Industrial processes: machine or relay state reporting

Interactive Control & Automation

With network integration, the Dry Contact Sensor can trigger logic actions in the system. Examples include:

• Initiating sirens or strobe lights when a contact opens
• Auto-activation of additional HVAC units when a fault is detected
• Combination with water or smoke sensors for complex alarm chains

Software Configuration

The web interface allows users to set custom parameters for:

• Configuring alarms for either contact opening or closure
• Defining alert times (e.g., outside business hours only)
• Assigning SMS/email recipients
• SNMP trap configuration for NMS

Security and Tamper Protection

Built-in disconnect alarm signals wire breaks or tampering, making the sensor not just a tool for signal acquisition but also for security monitoring.

Advantages of the AKCP Dry Contact Sensor

• Reliable monitoring of dry contact signals
