CAN Alarm

CAN-Ready Alarms & Lighted Alarms emit loud sound in a panel-mount body on your existing J1939 System.

The industry leader in audioalarm technology is now CAN-Ready! Use our audibles and lighted alarms on your existing J1939 CAN network.

Available Tone Types:
Multiple ToneMultiple


Floyd Bell is proud to offer the CAN-Alarm, a panel mount piezo alarm that functions on any CAN Network using the SAE J1939 protocol! This ground-breaking new electronic buzzer uses a brand-new body style in order to provide sound levels up to 108 dB (±5) on your CANbus network! Sharing all of the great features of the Turbo™ Series alarms in a slightly larger package, this tamper-proof body is epoxy encapsulated and polarity protected. The solid-state electronics are housed in a 94 V-O flame retardant, heavy-duty thermoplastic enclosure with a stainless steel, corrosion-resistant sound diaphragm. NEMA type 4X environmental security when used with optional gasket.

The CAN-96-930 is arbitrary address capable, meaning it can claim a different address if an address conflict occurs. Rather than being "pre-canned" with specific sounds, the device is configurable for many sounds or tones via messages received on the network. This allows the alarm to be useful to communicate multiple audible tones/sounds for different alarm conditions. A detailed Communications Reference specifies tone types and specific PGN instructions for activating different tone and sound combinations on the network. 


NEW Twin CAN Alarms are CAN-Ready J1939 Lighted Alarms!

Floyd Bell's ground-breaking new Twin CAN Lighted Alarm is a panel-mount piezoelectric audio alert that emits a daylight-viewable bright light when activated, effectively combining an audible alert with an LED panel light into one convenient multi-sensory alarm device. The energy efficient device operates on your J1939 CAN Network and can be controlled by the network to illuminate the light along with a vast selection of different tone types.


These bright, lighted alarms are the same size body as the CAN Alarm, requiring a 1.5” panel hole. The body is slightly larger than the standard Twin Turbo™ Series Alarms, which means the sound cavity is tuned for 108 dB (±5) at lower frequencies than its smaller size, two-terminal counterpart.


Like Floyd Bell's Turbo Light™ LED Panel Indicators, Twin CAN Alarms feature InGaN LED technology, providing high intensity output. A special illuminated enclosure creates an attention-getting "halo" ring of light in your choice of 5 BRIGHT colors.  And the tamper-proof low-profile design of the unit is curved so the light can be seen even from the side, offering an impressive 180° dispersion!
