How to Send Alarms to Motorola MOTOTRBO Radios with SeQent

Most industrial plants already have Motorola MOTOTRBO two-way radios on the plant floor. These radios offer reliable communication independent of Wi-Fi or cellular coverage, operate in high-noise environments, and have battery life measured in shifts rather than hours. The problem is that SCADA alarm systems and radio networks have historically been completely separate, requiring operators to watch HMI screens and manually radio maintenance teams when issues arise.

SeQent eliminates this gap with native integration between industrial SCADA platforms and Motorola MOTOTRBO/WAVE PTX communication devices.

1. How the Integration Works

SeQent connects directly to the Motorola MOTOTRBO radio infrastructure through a native, proprietary integration. This is not middleware, email-to-radio scripting, or a third-party adapter. It is a purpose-built, maintained connection.

When a SCADA alarm fires, FPAM processes the alarm, applies routing and escalation rules, and delivers the notification directly to the designated radio or talk group. Notifications are delivered as both text messages displayed on the radio screen and text-to-speech audio announcements broadcast over the radio channel.

Operators can acknowledge alarms directly from the radio. The acknowledgment flows back through SeQent and is logged, creating a documented response record and closing the alarm loop.

2. Key Capabilities

Text alerts: Alarm details displayed on the MOTOTRBO radio screen, including alarm name, priority, area, and value.

Text-to-speech audio: Alarm information converted to spoken voice and broadcast over the radio channel or talk group. Personnel hear the alarm without looking at the radio.

Two-way acknowledgment: Operators press a button on the radio to acknowledge the alarm. The acknowledgment is logged in SeQent with timestamp and operator identity.

Talk group routing: Alarms can be sent to specific talk groups based on alarm area, priority, or shift. This targets the right team without broadcasting to the entire plant.

WAVE PTX support: Voice announcements can also be delivered to Motorola WAVE PTX push-to-talk devices, with mirroring to connected MOTOTRBO talk groups.

3. Setup Process

Step 1: Verify MOTOTRBO Infrastructure

Confirm your Motorola MOTOTRBO system is operational with talk groups configured. SeQent connects to the MOTOTRBO infrastructure, so the radio network must be in place.

Step 2: Configure the SeQent Radio Link

In the SeQent Web Admin, navigate to the radio link configuration. Enter the MOTOTRBO infrastructure connection parameters. Test the connection to confirm SeQent can communicate with the radio system.

Step 3: Map Alarms to Radio Channels

Configure which alarms route to which radios or talk groups. You can route by alarm area (all boiler room alarms to the utilities talk group), by alarm priority (critical alarms to the supervisor channel), or by shift (current shift’s maintenance team).

Step 4: Configure Message Templates

Define the text and voice message templates for radio delivery. Include dynamic fields such as alarm name, priority, area, value, and timestamp. Keep text messages concise since radio screens have limited display space.

Step 5: Test Delivery

Trigger a test alarm from your SCADA system. Verify the text message appears on the designated radio. Verify the text-to-speech audio broadcasts on the correct talk group. Test acknowledgment from the radio and confirm it is logged in SeQent.

Common Issues

Radio not receiving messages: Verify the SeQent radio link is connected, the correct talk group is configured, and the radio is on the correct channel.

Text-to-speech not playing: Check the audio configuration in the radio link settings and verify the radio’s audio volume and channel settings.

Acknowledgment not registering: Confirm the radio is configured for two-way communication and the acknowledgment timeout has not expired.

4. Value

Motorola radio-based alarm notification eliminates the gap between SCADA alarm systems and plant-floor communication. Operators receive alarms on devices they already carry, can acknowledge from the field without returning to an HMI, and every interaction is logged for compliance and continuous improvement.
