Overview
The Dahua ARM310-W2 is a small wireless input expander. It has one dry-contact input for a wired detector, such as a metal door contact, a beam detector output or a gas detector relay, and it sends that detector’s state to a Dahua wireless hub over two-way radio. It lets you add an existing or specialist wired sensor to a wireless alarm without running cable back to the hub, which suits steel shutters, rolling doors and detectors that only have a relay output.
Is it right for you?
- It suits one wired detector with a dry-contact output, in a Dahua 433 MHz wireless alarm.
- The input is a dry contact only: a powered detector still needs its own supply.
- If you need to power a low-current detector from the module, or want a device-moved alarm, the ARM320-W2 suits better.
- Indoor use only, -10 to 55 °C.
Key features
- One dry-contact input that accepts normally open (NO), normally closed (NC) or pulse wiring.
- The zone can be set as intrusion, medical, fire, emergency, gas or tamper, so the hub reacts in the right way.
- Up to 1,000 m open-space range with frequency hopping and AES128 (Advanced Encryption Standard) encryption.
- Tamper alarm, test mode and a signal strength check for placement.
- Temperature measurement from -15 to 65 °C, accurate to within 1 °C.
- Slim 100.2 x 20.8 x 20.3 mm body on a mounting bracket.
- One CR123A battery: about 4 years with the input in NO mode, 2 years in NC or pulse mode.
What else you need
A Dahua 433 MHz wireless hub, such as the ARC3000H, the Dahua app for zone setup, a CR123A battery and the wired detector it will monitor. A detector that needs power must have its own supply.
Installation
An alarm installer can fit it. Mount the module on its bracket near the wired detector, wire the detector’s contact to the input, set the input type to match (NO, NC or pulse), then pair it with the hub and assign the zone type in the Dahua app.
Software and licences
Zone type, input mode and test mode are set in the Dahua app. Firmware updates arrive through the cloud.
Before you buy
- Battery life depends on the input mode: about 4 years in NO mode, 2 years in NC or pulse mode.
- The input is a dry contact only, so a powered detector still needs its own supply.
- Indoor use only.

Questions about this product
What can I connect to it?
Any wired detector with a dry-contact output, such as a metal door contact, a beam detector or a gas detector relay, wired as NO, NC or pulse.
Does it power the detector?
No. The input is a dry contact only, so a detector that needs power must have its own supply.
How long does the battery last?
About 4 years with the input in NO mode, or 2 years in NC or pulse mode, on one CR123A battery.
How far can it be from the hub?
Up to 1,000 m in open space. Use the signal strength check at the planned spot.
Can it be used outdoors?
No. It is rated for indoor use, -10 to 55 °C.
