VESDA
A VESDA consists of the host, power box, and sampling pipe. The VESDA host includes two
types: VLS and VLP. The VLS is a four-pipe scanning detector that can monitor each pipe and
generate alarms. The VLP is a standard detector that can only conduct general monitoring but
not for each pipe. The host should be configured based on practical requirements.
The detector host consists of a suction pump, filter, high-sensitivity smoke detector, and
precision electrical analyzer. The fan sucks air samples from the monitored environment
through the air sampling pipe to the smoke detector, which will analyze and process the
samples and calculate the amount of smoke in the air. If the smoke density exceeds the preset
alarm threshold, the system blinks and sends alarm signals to the ECC.
A dedicated PPS-004 power box should be configured for the VESDA. The PPS-004 power
box should be supplied by a 220 V AC main input and supplies 24 V DC power to the
VESDA host. Backup batteries should be deployed for the PPS-004 power box.
The features of the VESDA are as follows:
High sensitivity and wide sensitivity adjustment range (0.005–20% obs/m), able to detect
regular fires at an early stage as well as the particles generated by the softened insulation
layer of an overloaded power cable
