Forklift Backup Alarms

This page holds about 65 listings for the alarm that sounds when a machine reverses or a platform tilts: the forklift backup alarm, plus the warning alarms, wire harnesses, mounting nuts and decals that go with them. The group is smaller than most electrical pages, and it leans heavily toward Genie aerial lifts, so it helps to know what the listings call each type.

Forklift Backup Alarm and Warning Alarm Types

Only about 15 listings use the words "back-up" or "back up." Those come from several makes, including Toyota, Caterpillar, Bobcat, JLG and Tennant, for example "FOR TOYOTA BACK-UP ALARM 97DB - 12-24V 2000 SERIES 58150-U3330-71," "For Caterpillar 91304-05200, ALARM, BACK UP, Forklift GP25" and "Bobcat Back Up Alarm 7001044." One Yale and Hyster listing, "FOR YALE FOR HYSTER BACK-UP ALARM 97DB - 12-48V 150019322," names two makes together.

Most of the rest are worded as "warning" or "continuous" alarms, and 19 of those 27 are Genie: "FOR GENIE GR-12 WARNING ALARM 62164," "FOR Genie GR-20 ALARM - CONTINUOUS 6/28V-95/108DB-ULTRA SERIES 39540" and "FOR GENIE AWP-36S ALARM WARNING 45383GT." In all, 17 say warning and 10 say continuous. If you're replacing a beeper on a lift, those are the words to look for.

Reading the Voltage and Decibel Figures

Some alarm listings give their operating voltage and loudness in decibels, so you can compare both with the old unit: 17 of the 65 list both. Examples include 12-24V and 12-48V ranges, 97DB and 107DB ratings, and a Tennant listing that gives both a voltage range and a sound range, "(12-24VDC)(82-107DBA)." The Genie continuous alarms show a wider span, such as "6/28V-95/108DB" and "6/30V-85/103DB-XTRA LOUD BEEP."

Numbers are easier than the descriptions. Genie's alarms keep returning to just a few: 39540 appears on eight listings, 45383 or 45383GT on seven and 62164 on five. A GT ending is often printed alongside the plain number, as in "NEW FOR Genie Alarm (FOR Genie: 45383, 45383GT)." Search the digits without the GT if the longer form finds nothing.

Wiring, Nuts and Decals

Some of the 65 aren't alarms at all, but they belong to the same job. There's "FOR GENIE 83140 ALARM WIRE HARNESS," a plastic ring nut for mounting alarms listed as "NUT - PLASTIC RING FOR ALARMS 72326GT," and five decals such as "FOR GENIE GRC-12 DECAL - TILT ALARM 114338." The decals also appear on the forklift decals and paint page.

For electrical neighbors, the forklift horns page covers the other warning sound on a truck, and forklift lights list the lamps.

Alarms by Make

After Genie's 37 listings, JLG has 7, Bobcat 4 and Snorkel 3. Yale, Toyota, Hyster, Skyjack, Terex Upright and Grove have two each.
