HBUS End of Line Module

Class 5 Elm

The HBUS End of Line Module (ELM) protects against attacks (sensor tampering, disablement or insider attack) between alarm sensors and control hardware in a security system. Without an ELM, sites are susceptible to sophisticated attacks, potentially rendering high value assets unprotected.

The ELM sends regular heartbeats, ensuring that alarms are raised if communications with the ELM are severed.

For the AS/NZS 2201 Class 5 standard, the ELM forms part of a compliant Gallagher Class 5 Intruder Alarm System.

Features and benefits

The ELM is a small PCB encapsulated in a protective potting resin and plastic casing, with a unique device serial number. The module plastic measures 32mm x 17mm x 10mm, and is designed to fit inside the tamper-proofed housing of a high grade alarm sensing device (such as PIR or contact sensor), or in a tamper-proofed junction box.

  • Full end-to-end authentication and encryption, preventing non-authenticated sensor inputs communicating unencrypted with controllers.
  • Field upgradeable code with plug and play authentication for quick and secure installation.
  • Small form factor for an easy install into almost any sensor.
  • Sensor walk-test functionality is included, removing the need to run additional wiring.
