Volume increases as voltage increases.

The light with a pulse tone alternates on/off to draw greater attention than the light with a continuous tone.

Lights combine high-visibility strobes with a buzzer that warns workers of hazards even when they’re outside a direct line of sight.

Light intensity is measured in candlepower (cp), which indicates how bright a light appears at a distance. Common examples include a car’s taillights (50 cp), traffic signals (600 cp), headlights (15,000 cp), high beams (50,000 cp), and police car searchlights (150,000 cp).

The revolving motion of the light makes these more visible than flashing lights. The bell alerts workers when they're outside a direct line of sight.

Horns are UL and C-UL listed for indoor and outdoor use in Class I, Division 2, Groups A, B, C, and D; Class II, Division 2, Groups F and G, and Class III, Division 2 hazardous locations. You can select up to three programmable tones, each corresponding to a different warning. If multiple signals are triggered at once, only the highest priority signal will sound.

Sirens can emit both continuous and pulse tones—pulse tones alternate on/off to draw greater attention than continuous tones.

Styles A and C are also known as piezo buzzers.

For Styles B and C, the volume increases as voltage increases.

Buzzers with a pulse tone alternate on/off to draw greater attention than buzzers with a continuous tone.

Buzzers with both a continuous and pulse tone can be wired to trigger two alerts, each corresponding to a different warning. If the continuous and pulse tone are both triggered at the same time, only the continuous tone will sound.

Attract more attention with a strobe light as well as an audible alarm. Arm and disarm these alarms with a key. They sound an alarm and emit short, intense bursts of light when a door is opened without authorization and the alarm and magnetic contact are separated. All require a mortise lock cylinder (sold separately) for operation.

Mount an optional rim lock cylinder (not included) on the opposite side of the door to arm and disarm these alarms from the outside.

In addition to an audible signal, these alarms flash a high-intensity strobe to draw attention during fire emergencies.

Styles A and C have a strobe that helps comply with ADA standards for photosensitivity when properly installed.

Surface mount using an outlet box (sold separately for Styles A, B, and D).

Protect your detectors from damage and tampering.

Link multiple detectors in tandem to warn occupants outside the vicinity about potential fire hazards; if one unit is activated, they're all activated. These detectors produce their own signal when visible smoke particles are detected. A backup battery provides protection in case of power failure. Detectors cannot be sold to Canada due to import regulations.

Connect and monitor your fire alarm system. Control panel comes with all the circuitry needed to power and monitor devices for up to five zones. These devices can include up to 30 smoke or carbon monoxide detectors as well as an unlimited number of heat detectors and fire alarm stations. Indicators show the status of each zone. The control panel has one relay for connecting alarms such as buzzers, bells, and lights.

The control panel requires two 12-volt batteries (not included) for operation; in case of power failure, it will use the batteries as a backup power source.

Alert others to moving vehicles. These bells mount directly to a vehicle's wheel hub, without switches or wires.

Dual-direction bell sounds when the vehicle moves forward and when it moves in reverse.

Single-direction bell sounds when the vehicle moves forward (if mounted on the left side) or when it moves in reverse (if mounted on the right side).

These alarms beep loudly and repeatedly when a vehicle moves in reverse. Wire them between the vehicle's battery and reverse lights. Alarms are resistant to vibration, dust, and moisture.

Alarm with automatic volume control detects the sound level around a vehicle and sets the alarm volume 5 dBA above that level.

Optional backup alarm switch activates the alarm when you shift into reverse, so you can use the alarm on a vehicle without backup lights.
