Overview

The Honeywell / Morley‑IAS 795‑005 is a plug‑in RS‑232 communication/interface module for ZX series intelligent fire alarm control panels. It provides an optically‑isolated serial communications port for single point‑to‑point links (for example leased/modem links or BMS / third‑party graphic front‑end connections).

• Plug‑in format for quick installation into ZX series control panels.
• RS‑232 serial interface — single point‑to‑point communications.
• Optically‑isolated port for improved electrical protection and signal integrity.
• Compatible with the family of serial modules (RS‑485 and Hi‑485 variants available).

Who is this for?

• Systems integrators and installers needing a serial link between ZX series panels and building management or third‑party front ends.
• Maintenance teams replacing or upgrading communications modules on Morley‑IAS / Honeywell ZX panels.

Safety & compliance

• Install only by a qualified fire‑alarm engineer in accordance with local regulations and the manufacturer's installation instructions.
• Check local approval/marking requirements (CE / UKCA / other) and verify compatibility with your panel firmware before installation.

Notes

• For full terminal pinout, wiring diagrams and protocol details, refer to the official datasheet / installation manual (available from Honeywell / Morley‑IAS or authorised distributors).
