- Addressable fire alarm
The Dahua DHI-HY-1400-CTXF addressable input module with 24 V supply links the fire panel to external devices that have no address of their own. The module monitors the state of a dry contact and reports it to the panel as a separate addressable event: a valve has operated, a pump has started, a damper has changed position.
Advantages
- Brings any equipment with a relay output into the addressable system
- Line supervision up to the connected device: breaks and shorts are reported as faults
- Its own address in the loop — the panel shows exactly which device changed state
- 24 V power from the system supply, no separate line needed
- Compact housing for mounting in a panel or next to the monitored device
Applications
- Monitoring valves, dampers and fire pumps
- Receiving signals from suppression and smoke extraction systems
- Integrating third-party equipment into the addressable system
- Supervising the position of fire doors and dampers
Frequently asked questions
How does an input module differ from an output module?
An input receives a signal from external equipment and passes it to the panel. An output does the opposite — it closes a contact on the panel's command and starts external equipment.
How many devices can one module handle?
The module supervises a single dry-contact circuit. For several independent signals, separate modules or an input/output module are used.
Does it need its own power supply?
The module runs on 24 V from the fire alarm system supply, so a separate unit is not usually required.
