A wireless alarm hub on the 868 MHz band that splits a building into separate areas.

This alarm hub brings wireless detectors, sirens and IP cameras together at one point. It runs redundantly across Ethernet, Wi-Fi and the cellular network, and carries alarms to a monitoring center over the SIA and SoftGuard protocols. It draws mains power and falls back to the built-in rechargeable battery during an outage.

150channels

Large peripheral capacity

Connects keyfobs, sirens, keypads, repeaters, PIR cameras and I/O transmitters to the same hub.

868.0–868.6MHz

Frequency hopping wireless band

It talks to peripherals two ways and changes band in noisy environments.

32areas

Independent area management

It sets up rooms in a building as separate areas and disarms them separately.

8channels

Alarm verification with IP cameras

It uploads IP camera footage to the mobile app the moment an alarm triggers.

64inputs

Wired alarm input expansion

Transmitters bring wired detectors into the system as well.

50messages

Offline alarm cache

It stores alarm messages while the network is down and sends them once it returns.

IN DAILY USE

Arming and disarmingThe app, a keypad, a remote control, a card and a schedule arm and disarm the system.

Voice broadcastThe telephone line and the local speaker announce the alarm status out loud.

Reporting to a monitoring centerThe SIA and SoftGuard protocols carry alarms to a monitoring center.

While charging, the operating temperature range narrows to 0 °C – +45 °C. The product is certified to the EN 50131 series with Security Grade 2 and Environmental Class II.
