5533M Series
Adaptatone Electronic Signal Explosionproof, Two Outputs
- 5 tone capability – No additional tone modules needed
- Internal volume control
- Corrosion resistant heat flowed epoxy finish
- Supplied with factory sealed 1/2″ (13mm) threaded fitting for quick installation
The Edwards 5533M Adaptatone Signal is an explosionproof, heavy-duty industrial, tone-selectable, signaling device capable of producing volume-controlled, high-decibel tones. The signal accepts up to two contact closures and delivers two audible output signals selected from the 55 tones available.
B-KM-8130 Series
AdaptaHorn Hazardous Location Single Projector AC Vibrating Horn
Corrosion resistant electrostatic heat flowed epoxy finish
The Edwards B-KM-8130 Series is a heavy-duty, high decibel, vibrating horn signal designed for use in hazardous locations.
Two mounting lugs are provided on either side of the unit for wall mounting. The housing is tapped on one side for 1/2″ (13mm) conduit to allow for field wiring installation.
Ideal for use where sound projection in a single direction is required or specified in hazardous atmospheres where explosion proof and dust tight features are required.
Hazardous Location Bells
439DEX-AW
- 6″, 8″ and 10″ gong sizes
- Low power drain for efficient operation over long wire runs
- Adjustment free self compensating plunger
- Corrosion resistant
The Edwards hazardous location fire bell is the finest heavy duty hazardous location bell available today. It delivers a distinctive, clear ring that is free of mechanical clatter. Vibrating bells produce a long, continuous ringing sound. The striker continues to rapidly strike the gong as long as current is applied.
Fire Alarm Bells
323D & 430D Series
- Vibrating and single stroke
- 6″ (152 mm), 8″ (203 mm) and 10″ (254 mm) gong sizes
- Red or gray finish
- Rugged, compact mechanism
- Heavy duty cast housing
- Low power drain
- Wide voltage selection
- Indoor or weatherproof
Kidde Fire Alarm Bells are diode polarized, vibrating bells designed for use with fire alarm applications. The gongs are made of selected alloy steel to sound the loud, resonant tone required in fire alarm systems.
5530MD-24AW
Adaptatone Millennium Multiple Tone Signal Diode Polarized for Fire AlarmCommunication, Single Output
- 55 tone capability – No additional tone modules needed
- Output up to 110 dB
- Suitable for Division 2 Locations
- Diode polarized for supervisory circuits
Captive Components The Edwards 5530MD-24AW Adaptatone Millennium is a heavy-duty industrial, tone-selectable, signaling device intended primarily for use in fire alarm systems and other applications requiring electrical supervision of signaling circuit field wiring. It uses a microprocessor circuit to create 55 distinctive tones A single tone may be selected by setting a miniature dip switch within the unit. The Adaptatone Millennium can be activated from field-wired, normally open contacts, or a 24VDC external voltage source such as an output of a PLC or Fire/Security panel. Normally open contacts can be obtained from the Cat. No. 5538-4 and/or Cat. No. 5538-4R Adaptatone Signal Actuators.
5540M Series
Adaptatone Millennium Central Tone Generator Synchronized System Signaling,Four Outputs, RS485 Activation
- 55 tone capability – No additional tone modules needed
- PLC Compatible
- Captive Components
- Centralized programmable tone selection
- System-wide priority tone selection
- RS485 models available
The Edwards 5540M Millennium Central Tone Generator has been designed for applications where simultaneous signaling of a high decibel, heavy duty signal is required. The tone generator assures a synchronous signaling sound from all remote speakers. The Millennium Central Tone Generator produces the 55 standard Adaptatone sounds. Four tones may be activated from field-wired, normally open contacts, or a 24VDC or 120VAC external voltage source such as an output of a PLC.
