Siemens ALD-2I Analog Loop Driver (REFURBISHED)
The Siemens ALD-2I Module is a powerful addressable loop driver designed for integration with Siemens MXL, MXLV, and MXL-IQ fire alarm systems. This versatile module connects intelligent addressable devices, such as detectors and alarms, to the fire system, providing a highly reliable communication interface. The ALD-2I supports up to 60 devices per circuit, offering a scalable solution for complex fire alarm networks.
Key Features:
- Supports Up to 60 Devices per Circuit: Easily connect multiple alarm-causing, trouble-causing, and supervisory devices, plus remote devices like CZM-1.
- Flexible Wiring: Compatible with both Class A and Class B wiring configurations, and allows T-tapping without losing supervision in Class B installations.
- Supervised Circuits: Provides full supervision of all connected devices, ensuring the reliability and health of the system.
- Onboard Microprocessor: Operates independently in case of a main processor failure, continuing to initiate alarms and manage system operations.
- LED Indicators: Equipped with four LEDs for easy monitoring of alarm, trouble, transmit, and ground fault conditions.
- Direct Integration: Plugs into the MOM-4 card cage, ensuring seamless integration into the MXL system.
- Compliant: Meets NFPA 70 standards, providing power-limited circuits to enhance safety and reliability.
