VL-SLC
SIGNALING LINE CIRCUIT MODULE
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
FEATURES:
​
• Designed to meet UL864 10th Edition requirements.
​
• Supports up to 254 addresses.
​
• Supports Class X & Class A wiring configurations.
​
• “Heartbeat LED” that shows communication between the module and the motherboard.
​
• Extensive front unit status indications.
​
• Time saving AUTO-LEARN facility.
​
• Quick and easy to install.
​
• 500mA max load (20 ohms loop resistance), or 200mA (50 ohms) loop resistance.
​
• Double address detection
