Key Features
- Address settable from 001 to 254 by a dedicated programmer
- Loop powered and low standby current (3mA)
- Mounts to optional 4-inch square junction box
- Status indicator LED
- Supports Class A and Class B wiring
Overview
The Velocity Addressable Zone Module is intended for use as part of an addressable two-wire fire alarm system. It can be connected to conventional detectors and monitors and transmits the status (normal, open, short or alarm) of detectors within the zone to the control panel.
It can be wired for Class A (Style D & E) and Class B (Style B & C) operation and has a built-in short-circuit isolator (SCI). The SCI prevents entire loop failure in the event of a short on the loop.
Velocity Addressable Zone Module has a three-coloured LED to indicate the status of alarm, polling and SCI and can be mounted directly to a 4-inch square electrical box.
Approvals
All components in the Velocity range are UL certified and comply with the requirements of Underwriters Laboratories (UL) 864 Control Units and Accessories for Fire Alarm Systems 10th Edition.
