It may be worthwhile to yank the old FAR/AIM off the shelf once in a while -- or just open up a handy, free link: http://www.faa.gov/air_traffic/publications/atpubs/aim/Chap3/aim0302.html
 

(c) Unless otherwise authorized by ATC, an operable radar beacon transponder with automatic altitude reporting equipment. 

NOTE-

ATC may, upon notification, immediately authorize a deviation from the altitude reporting equipment requirement; however, a request for a deviation from the 4096 transponder equipment requirement must be submitted to the controlling ATC facility at least one hour before the proposed operation. 

REFERENCE-

AIM, Transponder Operation, Paragraph 4-1-19. 

6. Mode C Veil. The airspace within 30 nautical miles of an airport listed in Appendix D, Section 1 of 14 CFR Part 91 (generally primary airports within Class B airspace areas), from the surface upward to 10,000 feet MSL. Unless otherwise authorized by ATC, aircraft operating within this airspace must be equipped with automatic pressure altitude reporting equipment having Mode C capability. 

However, an aircraft that was not originally certificated with an engine-driven electrical system or which has not subsequently been certified with a system installed may conduct operations within a Mode C veil provided the aircraft remains outside Class A, B or C airspace; and below the altitude of the ceiling of a Class B or Class C airspace area designated for an airport or 10,000 feet MSL, whichever is lower.

According to that there is no need to call the tower in advance,just stay outside the controlled airspace.

That message below is citing the regs for the Mode C veil (30 mile radius line) around Class B airspace. Planes which were not originally equipped with an electrical system are not required to have a transponder capable of Mode C reporting within the outer veil. However, to enter Class B airspace you must have a transponder capable of Mode C (or call the controlling authority at least one hour before you plan to operate in Class B and ask for permission).
