Ajax EN54 Fire Detection I/O Module (2X2) White

EN54 I/O Module (2X2) Jeweller blurs the limits for use cases and compatibility in EN 54-certified Ajax setups. It automates responses to emergencies by integrating gates, door locks, lighting, or alert systems through the module outputs. Its inputs allow complementing the setup with beam smoke detectors, elevator control panels, HVAC systems, or other wired third-party devices to address any fire or life safety scenario. Designed to deliver an Ajax-level experience, the module offers out-of-the-box communication with the CIE, intuitive configuration via Ajax apps, and zero-hassle maintenance.

Communication (Jeweller)

• Technology: Proprietary wireless communication to transmit commands, alarms, and events

• Key features: Two‑way communication; advanced sabotage protection; block encryption with dynamic key; instant notifications; remote control and configuration in Ajax apps

• Frequency bands (depends on sales region):

  • 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

• Maximum ERP: up to 20 mW
  Automatic power control reduces power consumption and radio interference

• Radio modulation: GFSK

• Radio communication range: up to 1,700 m (open space) between the device and a CIE or range extender

• Encrypted communication: Block encryption with dynamic key for stored and transmitted data

• 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 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, 6.2 kΩ
  Four resistors for each input are included in the complete set

• Length of wired connection to third‑party devices: up to 100 m (with 2×1.5 mm² / 16 AWG fire‑resistant cable)

• Cable cross‑section: 0.4–2.5 mm² (21–13 AWG)

Outputs

• Number of output lines for third‑party devices: 2

• Output 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)

• Cable cross‑section: 0.4–2.5 mm² (21–13 AWG)

Key Features & Behaviour

• Event types: Configurable in Ajax apps (PRO or user with admin rights). Selected type determines notification texts and CMS event codes for connected wired devices

• Fail‑safe mode: If the module is offline, discharged, or has hardware problems, it automatically activates the connected devices

• Installation: Indoor use only

Sabotage & Integrity Protection

• Tamper alarm: Notifies attempts to detach the module from the surface or open the front lid

• Protection against spoofing: Device authentication

• Connection loss detection: After 36 s (depends on Jeweller settings)

• Input monitoring: Detection of wired connection loss, short circuits, and malfunctions when EOL/2EOL/3EOL connection is used (depends on connection type)
