6th Edition
Introduction
Models VDOT-H2 and VDOT-H2-H is an attractively styled, low profile heat detector for use with the Fire Alarm Control Panel of Velocity MMP control panel series.
These heat detectors are intelligent (addressable) detectors and have the ability for each detector address to provide exact detector locations.
The detector sensitivity is continually monitored and reported to the panel. The detectors incorporate a highly linear thermistor circuit, with the thermistor mounted externally.
The specially designed cover protects the thermistor whilst allowing maximum air flow. The thermistor circuit produces a voltage proportional to the temperature which is scaled, and transmitted as a digitally encoded value to the control panel.
The VDOT-H2 and VDOT-H2-H require compatible addressable
communications to the control panel in order to function properly.
All detectors have random addresses from the factory before
installation. The VDOT-AD2 Address Programmer is used for setting the address between 1 and 254 decimal of all devices prior to installation. Once addressed connect these detectors to only UL listed-compatible control panels.
The VDOT-H2 is a 8.3°C (15°F) rate-of-rise temperature heat detector with 57°C (134°F) fixed temperature alarm.
The VDOT-H2-H is a high temperature heat detector with 83°C
(181°F) fixed temperature alarm.
