Ajax MultiTransmitter Jeweller - 18-Zone Integration Module
MultiTransmitter Jeweller lets wired detectors, contacts and other wired devices from any maker work as part of an Ajax wireless alarm. It has 18 wired zones on its board and sends their alarms, faults and tamper events to the hub over the Jeweller radio, which makes it a practical way to take over an existing wired installation or to mix wired and wireless devices on one system. It runs from the mains, takes a 12 V backup battery inside its casing, and powers the devices wired into it. Two tamper switches report if the lid is lifted or the unit is pulled off the wall. Choose black or white above.
Also listed as 35278 (black) and 35279 (white). Ajax model ID MTR.Y.J.

Common questions
Can I use my existing wired detectors with an Ajax system?
Yes. Wire up to 18 of them into MultiTransmitter Jeweller and it reports each one to the Ajax hub by radio. Each zone is named and set up in the Ajax apps.
Which wiring types does it support?
NC, NO and EOL, with 2EOL and 3EOL as well depending on the firmware version. With EOL, 2EOL or 3EOL wiring it spots a cut wire or a short circuit straight away.
Does it need a battery?
It runs from the mains. The casing takes a 12 V backup battery of up to 7 Ah, which is not included.
Can it power the detectors wired to it?
Yes. It supplies 10.5-15 V DC to connected devices, up to 1 A in total.
Is it graded for alarm use?
Yes. It is certified to Security Grade 2 and environmental class II by TREZOR TEST s.r.o., and Ajax lists it against PD 6662:2017.
Can it be fitted outside?
No. Ajax designs it for indoor use only, at -10 °C to +40 °C.
