|The HRL Fire Horn is an add-on siren you can use with fire panels such as the Silent Knight or Fire-Lite models. You can also use these on alarm systems as well like our DSC, Honeywell or Interlogix hardwired systems. The horn is 5.6˝ L × 4.7˝ W × 1.25˝ D and is compact enough to fit in small spaces. The power rating for this horn is 8 to 17.5 V (12 V nominal) or 16 to 33 V (24 V nominal). The wiring used for this horn is 12-18 gauge wire, 2 conductor. These horns will sound at up to 90 decibels depending on what voltage is used and what setting you have it set to.
The unit comes with a back mounting box and all the hardware you'll need for install. The HRL has five types of adjustable horn tone which can be set by a dial on the unit itself. The 5 types are broken into 10 levels. You have temporal high/low, non-temporal high/low, 3.1 KHz temporal high/low, 3.1 KHz non-temporal high/low, coded high, and 3.1 KHz coded high.
The horn will have different current draws based on the tone that you choose. The power draw will range from 28 - 54 mA depending on what level of tone you choose.
