Narrative:

During the climb; shortly after passing FL260; the baggage smoke cas (crew alerting system) message illuminated and extinguished several times in rapid succession; then extinguished for what would prove the remainder of the flight. No smoke was observed or detected by the crew or passengers at any time. The crew accomplished the baggage smoke checklist to isolate the baggage compartment. Although suspecting an erroneous baggage smoke sensor; they determined their best and safest course of action was to [advise ATC] and request an immediate diversion to [a nearby alternate]; which had fire rescue services; multiple long runways; VFR weather; and was only minutes away. During the descent; the pm briefed the passengers about the cas message and our plan to divert; shut down and allow emergency services to check over the aircraft. They understood the situation and were in agreement with our plan. The crew landed uneventfully and exited the runway where fire and airport authorities waited and gave them unobstructed access to the aircraft. With the aircraft quickly shut down; the PF exited and with the firemen present; opened the baggage compartment. The pm stood at the main cabin door ready to assist the passengers in case a rapid evacuation was necessary. Fire personnel utilized their detection equipment and determined there was no smoke residue and no fire had occurred in the baggage compartment. Once checked over and with the concurrence of the fire officials; the crew [advised] ATC; restarted the engines; and taxied to the ramp with the emergency vehicles following. After block in; fire crews once more looked over the aircraft; again confirming there was no fire/smoke; then departed.hopefully this event will provide maintenance information on the system integrity of the baggage smoke system; related sensors; and electrical components to prevent reoccurrence of this event in the future.
