| Capacity | |
| Communication | |
| Jeweller communication technology | Proprietary wireless communication technology to transmit commands, alarms, and events. Key features:
|
| Frequency bands | 866.0–866.5 MHz 868.0–868.6 MHz 868.7–869.2 MHz 905.0–926.5 MHz 915.85–926.5 MHz 921.0–922.0 MHz Depends on the sales region. |
| Maximum effective radiated power (ERP) | up to 20 mW Automatic power control to reduce power consumption and radio interference. |
| Radio signal modulation | GFSK |
| Radio communication range | up to 1,700 m up to 5,550 ft Between the device and control and indicating equipment (CIE) or a range extender in an open space. |
| Encrypted communication | All stored and transmitted data are protected by block encryption featuring a dynamic key. |
| Frequency hopping | To prevent radio interference and jamming. |
| Inputs | |
| Number of input lines for third-party devices | 2 |
| Input terminals | Input 1, Input 2 — inputs for connecting third-party wired devices Shield — common input for connecting shields of the cables that connect third-party wired devices |
| Type of connection | NO, NC, EOL, 2EOL, 3EOL |
| EOL resistance | 0.47 kΩ, 1.2 kΩ, 2.7 kΩ, and 6.2 kΩ resistors Four resistors for each input are included in the complete set. |
| Length of wired connection to third-party devices | up to 100 m up to 325 ft When 2×1.5 mm2 (16 AWG) fire-resistant cable is used. |
| Cross-sectional area of the cable | 0.4–2.5 mm² (21–13 AWG) |
| Outputs | |
| Number of input lines for third-party devices | 2 |
| Outputs terminals | Output 1, Output 2 — relay outputs for connecting third-party wired devices. |
| AC operating range | 10—250 V~, 5 mA to 10 A (resistive load) |
| DC operating range | 10—30 V⎓, 5 mA to 5 A (resistive load) |
| Cross-sectional area of the cable | 0.4–2.5 mm² (21–13 AWG) |
| Operating mode | pulse bistable |
| Pulse duration | from 1 s to 1 h 30 min Pulse duration can be configured for pulse mode in Ajax apps separately for each relay. |
| Key features | |
| Event types | An Ajax app specifies event types for wired device inputs. The selected type determines the text of alarm notifications and events of the connected device, as well as event codes transmitted to the CMS. A PRO or a user with admin rights can configure the event type in an Ajax app. |
| Automation scenarios | The scenarios can be configured in Ajax apps separately for each relay. |
| Fail-safe mode | If the module is offline, discharged, or has hardware problems, it activates the connected devices automatically. |
| Installation recommendations | The device is designed for indoor use only. |
| Sabotage protection | |
| Tamper button | Notifications of attempts to detach the module from the surface or open the front lid. |
| Protection against spoofing | device authentication |
| Connection loss detection | after 36 s Detection time depends on Jeweller settings |
| Input monitoring | detection of wired connection loss, short circuits, and malfunctions when the EOL, 2EOL, or 3EOL connection is used Depends on the connection type. |
