• -40°C to +66°C / -40°F to +151°F
• Units can be mounted using the 2-off ø9mm holes in the mounting lugs or through the back of the housing using the supplied gasket
seal.
• A121DC024 is approved for use as an audible signal appliance for fire alarm use – Public Mode (UL464 & CAN/ULC-S525) and produc-
es a minimum sound pressure level of P2: US: 93.67dB(A); CA: 101.2dB(A) / P3: US: 94.33dB(A); CA: 102.4dB(A) at 10 feet, (figures @
worst case 11.5Vdc).
• The A121DC024 produces a minimum sound pressure level of P2: US: 97.59dB(A) ; CA: 105.4dB(A) / P3: US: 100.63dB(A); CA:
107.5dB(A) at 10 feet (@24Vdc)
• For Fire Alarm applications, the Sounder Volume must be at the highest setting, (see volume control section). For fire alarm use, Tone
12 as shown below must be selected:
• Connection Terminals: Pluggable
