Velocity VL-SLC Installation Instructions Manual

General
The plug-in SLC module provides power for and handles communications to the analogue addressable devices. The
SLC continuously monitors the analogue values of all devices and displays this value on the control panel as a
percentage of the alarm threshold value. Up to 254 addresses (500mA max load) can be connected to a single SLC.
The addressable devices use soft addressing using the VDOT-AD2 handheld programming tool which helps minimise
the potential for error and reduce the installation time associated with traditional hard addressing. The AUTO-LEARN
facility provided in the Velocity series control panel saves considerable time and effort when installing a new loop or
when changing device configuration.
It allows the system to learn for itself what devices have been installed on the loop.
Installation
The MMP panel uses the expansion port number to reference modules. It is recommended that any SLC modules are
fitted first to the first expansion ports, so that the loop circuit numbers follow a logical sequence (loop 1 in port 1,
loop 2 in port 2 etc.)
ATTENTION: THE PANEL MUST BE POWERED DOWN, AND DISCONNECTED FROM THE BATTERIES BEFORE INSTALLING
OR REMOVING ANY MODULES.
1. Ensure that the installation area is free from any cables or wires that may get caught, and that there is enough
space on the DIN rail to mount the module. Also ensure that the DIN clip underneath the module is in the open
position.
2. Place the module onto the DIN rail, hooking the metal earth clip underneath onto the rail first.
3. Once the earth clip is hooked, push the bottom of the module onto the rail so that the module sits flat.
4. Push the plastic DIN clip (located at the bottom of the module) upwards to lock and secure the module into
position.
