Hochiki CHQ-DZM/DIN (HFP)-SCI Analog Addressable Dual Zone Monitoring Module Rail Type with Short Circuit Isolator

Hochiki CHQ-DZM/DIN (HFP)-SCI is an addressable module used in fire alarm systems.

Detailed Information

1. Two Two-Wire Fire Detector Line (Zone) Control

• It can control two two-wire fire detector lines (zones).
• It can transmit the signals from the detectors and fire alarm buttons on these lines to the control panel.

2. Addressable Technology

• It can be addressed with the Dip Switch on the module and the location of each module can be determined exactly.
• This helps locate the fire quickly.

3. HFP (Hochiki Fire Protocol)

• It provides fast and reliable data communication using Hochiki's proprietary fire protocol.
• It improves the overall performance of the fire alarm system.

4. SCI (Short Circuit Isolator)

• The internal short circuit isolator prevents the spread of damage when a short circuit occurs in the circuit.
• It ensures that the rest of the system continues to operate in the event of a short circuit.

5. Easy Installation and Maintenance

• It has a compact design that can be mounted on a DIN rail.
• It can be easily installed and maintained with its user-friendly assembly and maintenance features.
