TELEFIRE GIM-232

The TELEFIRE GIM-232 is a galvanic isolation module that enables secure RS-232 communication between TELEFIRE fire alarm control panels and external devices such as computers or serial printers. The module prevents ground loops and protects connected devices from electrical disturbances.

Key Features

• Galvanic Isolation: Provides electrical isolation between the fire alarm control panel and the connected RS-232 device.
• Ground Fault-Free Connection: Allows safe connection of grounded serial devices.
• Low Current Consumption: Draws only .5 mA in both quiescent and alarm states.
• Bidirectional Communication: Supports two-way data transmission via the RS-232 port.
• Device Protection: Protects the fire alarm control panel and connected devices from potential electrical issues.

Technical Specifications

• Current Consumption (Quiescent): .5 mA
• Current Consumption (Alarm): .5 mA
• Communication Port: RS-232
• Connection to Panel: Via COM-1 port (for ADR-3000)
• UL Certification: Complies with UL864 standard (Fire Alarm Subassemblies category)

Application Areas

• Computer Connection: Connecting a PC to the fire alarm control panel for configuration, supervision, or data logging.
• Printer Connection: Connecting a serial printer for printing event logs or reports.
• System Integration: Ensuring communication with external systems via an RS-232 interface.
• Secure Data Transmission: In environments where galvanic isolation and avoidance of ground faults are important.

Installation and Configuration

For the ADR-3000 panel, the GIM-232 module can be installed in the lower part of the panel’s internal mounting plate. For ADR-7000 series panels, installation details can be found in the specific panel’s manual. The module can be configured with a jumper for PC or printer mode in an ADR-3000 system.
