Chapter 3: Commissioning

Introduction

The commissioning of the ECU is done by performing a number of logical steps.
These must be done in the sequence provided to successfully complete the task.
Caution: Once the ECU is connected, the wiring must NOT be meggered. This
will cause irreparable damage to the circuit.

Prerequisites

Before commissioning, make sure of the following:
• The small hand tools are available for testing, connecting, disconnection, etc.
• That a good multimeter (preferably digital) is at hand.
• That you have all information relating to system zoning, relay mapping, relay
operating parameters, device sensitivity settings, etc. properly documented.
• That the drawings on hand indicate correct device positions, device
addresses, and device types with all relevant wiring runs.
• That the actuator is NOT connected to the ECU. For commissioning purposes
use a 2K2 Ω EOL (end-of-line) resistor in series with a LED (or the multimeter
across the resistor) to monitor the voltage at the location of the actuator.
• DO NOT connect power to the ECU.
• DO NOT connect power to the fire alarm control panel to which the ECU is
connected.
