MultiTransmitter 3EOL NF expander, white
White MultiTransmitter 3EOL expander, NF and Grade 2 version, to add up to 18 wired zones to an Ajax system
What it is and what it does
The white MultiTransmitter 3EOL NF turns the inputs of a wired installation into zones of an Ajax system. It accepts up to 18 inputs, with NO, NC, EOL, 2EOL or 3EOL alarm, pulse or bistable, and an end-of-line resistor of 1 kΩ to 15 kΩ. It talks over 868 MHz Jeweller radio, up to 2000 m in open space. It powers the detectors with two 12 V outputs and has a front and rear tamper.
Who Dartel installs it for
We fit it in homes and businesses that already have detector cabling and want to move to Ajax without building work. It is the NF and Grade 2 version, compatible with Hub, Hub Plus, Hub 2, Hub 2 Plus, Hub Hybrid, ReX and ReX 2. White suits light walls; if the technical room is dark, there is the black MultiTransmitter 3EOL.
How we install it
We place it indoors, next to where the detector cables arrive and near a socket, away from metal cabinets. We connect each zone and the detectors' 12 V power supply. We add it by QR code in the app, define the input type for each zone and check the signal and that each detector responds.

Frequently asked questions
How many wired detectors does it accept?
Up to 18 wired inputs. Each is configured according to the type of detector, with an end-of-line resistor of 1 kΩ to 15 kΩ if needed, and we leave it set during the installation.
What is the difference from the Transmitter?
The Transmitter serves a single detector and runs on batteries. This expander brings together many zones, powers the detectors from two 12 V outputs and accepts cable of up to 400 m.
