Carbon Monoxide Detector

The Costar C.O. Detector is a 100 volt carbon monoxide detector. When the detector is activated the transmitter will send a signal to a Silent Call receiver, up to 100 feet away. This product must be used in conjunction with a receiver, in order to receive the signal. Use either the Silent Call Shake Up Receiver with vibrator (bed shaker), the Silent Call Sidekick Receiver (with strobe), or the Silent Call Crystal Reflections Receiver, all listed below under related products.
