Description
Add wireless interconnect to your 240V alarms.
The Red Smoke RWB2 is a wireless mounting base for the R240 and R240RC 240V smoke alarms. Fit the alarm to this base and it links by radio to other Red alarms – including the R10RF wireless alarm – so a trigger on one sounds them all, with no interconnect cable to run between them.
Key Features
- Wireless mounting base for the R240 and R240RC 240V smoke alarms
- Wirelessly interconnects with Red 240V alarms and the R10RF wireless alarm
- Connects to the Red Smoke wireless controller (RAC / RACP)
- Non-replaceable 3V lithium battery, 10-year life
- 433.92 MHz; up to 40 wired or 20 wireless interconnected alarms
- 30m line-of-sight range indoors, 100m free field (150m wired)
- Screw terminals (active, neutral, earth loop, interconnect), 2 x 1.5mm²

- Tested to AS 4268 and AS/NZS CISPR 32:2015

Wireless Interconnect, No Extra Cabling
Running interconnect cable between existing 240V alarms is disruptive. The RWB2 avoids it: mount an R240 or R240RC on the base and the alarms link by radio on 433.92 MHz instead, with 30m line-of-sight indoors and 100m in free field. It carries its own non-replaceable 3V lithium battery so the wireless link keeps working through a mains outage.
Installer-Friendly
The base wires through standard screw terminals for active, neutral, earth loop and interconnect, each taking two 1.5mm² conductors. Two side knockouts suit conduit on a surface mount, and an internal knockout suits a ceiling mount. With the RWB2 fitted, the Red Smoke wireless controller (RAC or RACP) can also test, locate and silence the alarms from a wall point.
Q: What is the Red Smoke RWB2 for?
A: It is a wireless mounting base that adds RF interconnect to the R240 and R240RC 240V smoke alarms, so they can link wirelessly to other Red alarms instead of being hard-wired together.
Q: Does the RWB2 have its own battery?
A: Yes. It contains a non-replaceable 3V lithium battery with a 10-year life, which keeps the wireless link active during a mains power outage.
Q: Can the RWB2 work with the Red Smoke controller?
A: Yes. With the RWB2 fitted, the Red Smoke wireless controller (RAC or RACP) can test, locate and silence the connected alarms wirelessly.
