Description of EH24

• The EH24 Series is a low profile electronic horn that offers dependable audible output at the lowest current available. The EH24 Series horn offers a continuous or synchronizable temporal three in 2400Hz and mechanical tone, a chime, and whoop tone. All tones are easy for the professional to change in the field by using switches.The EH24 Series is shipped with the standard 4″ mounting plate which incorporates the popular Super-Slide® feature that allows the installer to easily test for supervision. The product also features a locking mechanism which secures the product to the bracket without any screws showing.

  The EH24 Series also features the patented Checkmate® – Instant Voltage Verification feature, which allows the installer to check the voltage drop draw and match it to the blueprint.

Specification of EH24

Notes:

• The sound output for the temporal 3 tone is rated lower since the time the horn is off is averaged into the sound output rating. While the horn is producing a tone in the temporal 3 mode its sound pressure is the same as the continuous mode.
• For nominal and peak current across ANSI/UL regulated voltage range for filtered DC power and unfiltered (FWR Full Wave Rectified) power, see installation manual. 12VDC models are DC only.
• Operating the horn in this mode at this voltage will result in not meeting the minimum ANSI/UL 464 reverberant sound level required for public mode fire protection service. These settings are acceptable only for private mode fire alarm use. Use the high dBA setting for public mode application (not applicable when using the chime tone. The chime tone is always private mode).
