A liquid immersion alarm is shown having a remote transmitter activated by a water immersion switch to generate an alarm signal. The alarm signal is received by a receiver that activates an alarm. Immersion of the transmitter and its immersion switch momentarily into water will not set off a false alarm due to a delay circuit associated with the transmitter. Once immersed, entrapped air will not interrupt the delay circuit from setting off the alarm due to a second delay circuit.
