VESDA-E VEA-040-A00 — addressable aspirating smoke detector that samples through up to 40 individually addressed microbore tubes.
An ordinary aspirating detector reports one obscuration level for the whole network, so an alarm says only that smoke is somewhere on the pipe. The VEA answers where: once Fire 1 is reached, a rotary valve scans each location in turn to identify the ones seeing the event.
- 40 addressable microbore tubes, 6 mm outer and 4 mm inner diameter, one sampling point each
- Up to 164 ft (50 m) per tube for open area protection, 328 ft (100 m) special application
- Chamber sensitivity 0.006%/ft to 4.88%/ft; Fire 1 thresholds 2.5, 1.3 and 0.5%/ft
- 18 to 30 VDC; 24.0 W quiescent and 36.9 W in alarm at 24 VDC; 3.5 A peak
- Seven programmable relays at 2 A, 30 VDC; VESDAnet, Ethernet, WiFi and a USB port
- Field-replaceable filter, pump, smoke sensor module and rotary valve; 21.8 lb (9.9 kg)
Check the suffix: the product guide covers the VEA-040-A00-UL, the North American variant with status LEDs. The optional VER-A40-40-STX Relay StaX signals fire source locations to a panel loop.
