BOSTON, Nov 10 (Reuters) - Industrial conglomerate Tyco International Ltd (TYC.N) said it expects its revenue to continue to slide until late in its 2010 fiscal year, sending its shares down 3 percent on Tuesday.

The maker of security and fire-control systems expects demand to remain soft through the first half of its current fiscal year -- which began in late September -- and set revenue and profit targets that allowed for the possibility of declines.

"We have assumed that the current environment continues well into the year... with some modest -- and I emphasize modest -- pickup in the second half of the year," Chief Executive Ed Breen told investors on a conference call.

The company looks for sales to fall at a low-double-digit percentage rate through the first half of the fiscal year, with the rate of decline slowing in the third quarter and growth perhaps returning by the fourth quarter, Breen said. Recent cost-cutting measures could help boost Tyco's bottom-line performance when revenue starts to pick up, he added.
