Overview
The Ajax ReX 2 Jeweller is a range extender for Ajax wireless alarms that also passes on photos from MotionCam detectors. It relays detectors in far rooms, upper floors or other buildings to the hub, linking to the hub by radio or by an Ethernet cable. It is mains powered with a built-in backup battery and works with Hub 2, Hub 2 (4G), Hub 2 Plus and other listed hubs.
Is it right for you?
- Choose it when a large home, office or group of buildings has detectors beyond the hub’s reach and uses MotionCam photo verification.
- The Ethernet link suits buildings where a network cable already runs between the hub and the far area, for example two blocks on one site.
- Up to 5 can be added to a compatible hub, each carrying up to 199 devices depending on the hub model.
- If you do not use MotionCam detectors, the ReX Jeweller does the same job without photo relay.
Key features
- Relays both Jeweller (alarms and events) and Wings (photo verification) radio protocols, up to 1,700 m from the hub in open space.
- Ethernet port (RJ-45, up to 100 Mbps) as the main or backup link to the hub.
- Alarms reach the hub in 0.3 s; photos in about 18 s over radio or 10 s over Ethernet, depending on settings.
- Mains powered from 110 to 240 V, drawing up to 10 W, with a built-in 2 Ah lithium-ion backup battery.
- Can run from 6 V DC or 12 to 24 V DC instead with the 6 V PSU (type A) or 12-24 V PSU (type A), sold separately.
- Tamper alarm and communication loss detection after 36 s.
- IP30 and IK06 rated enclosure, 163 x 163 x 36 mm, 364 g in white or 336 g in black.
