The handheld 40700 programming unit is used to manually assign addresses to devices on a fire detection loop.

The programming unit is connected to a device (detector, sounder, call point, module, etc.) by means of an adaptor or a special cable.

The device has four keys which allow incrementing or decrementing the address of a device, store an address into the memory of a connected device, or simply read the address of a connected device.

An LCD on the programming unit displays basic information on a connected device, such as the type of device, production and test dates, and battery status.

Velox 40700 Programming unit is not only used for Velox addressable devices but also for Conventional Devices. 40700 also provide indication of device parameters including contamination level of the optical detector chamber, analogue values, production date and others.
