The VES LLC VF2001 Ionization Smoke Sensor’s responsiveness and highly stable operation give it an extremely wide range of uses. The VF2001 can be used in areas where early warning of trouble from superheated or flaming combustibles is expected. The VF2001 is also constructed to be effectively used where outside RFI (Radio Frequency Interference) and other electrical interference is expected to be encountered.

STANDARD FEATURES (VF1020)

• Only 2.22” high, including base
• Simple and reliable device addressing method
• Very low current consumption using the unique “Low Power Mode”
• Automatic compensation for sensor contamination
• Built-in fire test feature
• Uses the noise immune Digital Communication Protocol (DCP),
...which uses interrupts for fast response to fires
• Can be used with VF7008 Sounder Base, low-profile VF7001 4” base, or
...VF7002 6” base

The VES LLC VF2002 Photoelectric Smoke Sensor is particularly suited to detecting visually dense smoke, typical of fires involving materials such as soft furnishings, plastic, foam or other similar materials which tend to smolder and produce large visible smoke particles. The sensor’s unique design allows fast response to flaming fires as well as smoldering fires, while eliminating false alarms.

STANDARD FEATURES

• Low Profile – Only 1.97” high, including base
• Simple and reliable device addressing method
• Very low current consumption using unique “Low Power Mode”
• Automatic compensation for sensor contamination
• Built-in optical fire test feature
• Uses the noise immune Digital Communication Protocol (DCP),
...which uses interrupts for fast response to fires
• Can be used with VF7008 Sounder Base, low-profile VF7001 4” base, or VF7002 6”

The VES LLC VF2003 Heat Sensor provides accurate temperature measurement data to the fire alarm control panel. This sensor is particularly suited to environments where smoke sensors are unsuitable because of the presence of system or cooking fumes such as in a kitchen.

The VES LLC VF7001 4” and the VF7002 6” mounting bases are electronics free and contain a simple rugged design with screw terminals for wiring connections. A common mounting base allows sensor interchange and maintains loop continuity when sensors are removed. A simple anti-tamper head locking system is provided which is enabled by removing a small plastic tab on the back of the sensor. Once locked, the head can only be removed using a small diameter screw driver.
