Description
Trigger lights, sirens and diallers from your alarms.
The Red Smoke RRURF is a stand-alone RF relay unit that bridges your Red smoke alarm system to auxiliary devices. When any interconnected alarm detects smoke, the RRURF switches a relay – driving strobes, sirens, automatic diallers or other equipment. It receives alarm signals by RF or hardwired SDI, so it suits both wireless and cabled installs.
Key Features
- Stand-alone relay unit, 240Vac mains powered
- 10-year 3V lithium battery backup (for the RF receiver)
- Receives alarm and low-battery signals by RF or hardwired SDI
- Volt-free relay output rated 250Vac, 5A resistive
- Continuous or pulse relay modes for different auxiliary devices
- Supports up to 20 wireless or 40 hardwired interconnected devices
- Compatible with Red Original and Red Professional 240V and 10-year lithium alarms
- Green LED (power) and red LED (low battery, RF pairing, fire trigger)
- ABS enclosure with conduit and duct entries for flexible mounting

RF or Hardwired – Flexible Integration
Position the RRURF within RF range of a smoke alarm, or wire it via hardwired SDI to an existing interconnected system. It receives alarm and low-battery notifications either way, and sends notifications onward to auxiliary devices by hardwired SDI. That makes it a practical bridge for retrofits as well as new cabled installs.
Drive Auxiliary Devices
The volt-free relay is rated 250Vac at 5A resistive and can be set to continuous or pulse operation, so it can switch strobes for the hearing-impaired, external sirens, automatic diallers, or building management inputs. By default the relay energises when an interconnected alarm detects smoke and releases when the alarm clears.
Q: What does the Red Smoke RRURF do?
A: It is a stand-alone relay that activates auxiliary devices – such as strobes, sirens or diallers – when a connected Red smoke alarm goes into alarm. It receives the signal by RF or hardwired SDI.
Q: How is the RRURF powered?
A: By a 240Vac mains supply, with a 10-year 3V lithium battery backup that keeps the RF receiver operating during a mains outage.
Q: How many alarms can the RRURF connect to?
A: Up to 20 devices wirelessly or 40 devices hardwired. It is compatible with interconnectable Red Original and Red Professional alarms running on 240Vac or a 10-year lithium battery.
