MODEL LCA
the economy model - 95±5db ONLY Low cost version of MPA-11 operates ONLY on 12 VDC system on single polarity. Protected against reverse polarity if the leads are installed incorrectly. Requires circuit filter accessory
(DF-2) for voltage spike protection.
 

MODEL MPA-II
• MODEL MPA-II/77/- (77±4dB)
• MODEL MPA-II/87/- (87±4dB)
• MODEL MPA-II/97/- (97±4dB)
• MODEL MPA-II/107/- (107±4dB)
Configured for broad range of application. Penetrating signal.

  Compact size installs in a space less than 4" square. Encapsulated electronics resist weather, shock, vibration and corrosion. voltage spike protected to 150 VDC. duel polarity. Actuated by back-up light circuit or switch on reverse gear mechanism (see accessories, below ). High impact housing.

HDA
With flexible HDAC, with cast SOUND urethane housing aluminum housing LEVEL
• MODEL HDA-107 - MODEL HDAC-107(107±4dB)
• MODEL HDA-112- MODEL HDAC-112(112±4dB)
• MODEL HDA-117- MODEL HDAC-117(117±4dB)
All models have penetrating warning signals ans sound levels for audibility in high noise levels. They are actuated by back-up light circuit or a switch on the the reverse gear mechanism. All are transient voltage spike protected to150 VDC. The sound pulse width is 1 to2 encapsulated for environmental protection.

Available on special order: Other voltage ranges in Reli-Alarm. Also electronic horns.

  LEVER/ACTION SWITCH (L/A-5)
For the use on fork lifts and vehicles primarily used on paved surfaces. May be used to actuate alarms on overhead or traveling cranes (two switches often required) (Weight: 3oz.;85gm. Size: 1 1/8" x 2 1/2" x 4 1/4"; 3 cm x 6 cm x 11cm).
    MICROSWITCH (MS-1)
Heavy-duty for off-highway use under rugged conditions. Weather resistant; pre wired with pigtails for fast installation. (Weight: 8oz.;225gm. Size: 1" x 4 1/2" x 7 1/4"; 2.5 cm x 11 cm x 18cm). If vehicle has back-up light circuit the lever/action switch or micro switch accessory is not required.
    CIRCUIT FILTER (CF-2)
Provides additional voltage spike protection for all electronic alarms where spikes may exceed the built-in protection of the alarm. Useful on electronic forklifts, small hand-operated forklifts and electric motor-driven graders. (Weight: 3.7oz.;105gm. Size: 1 7/8" x 2 1/2" x 1 1/8"; 5 cm x 6 cm x 3cm).
  POWER COVERTER (PC-110)
converts 110 VAC to 18 VDC (other voltage combination available on special order). Typically used on traveling cranes to actuate the electronic alarms. (Weight: 1.8lb.;82kg. Size: 2" x 2" x 5 1/2"; 5 cm x5 cm x 14cm).
Installation - Read and follow installation and maintenance instructions packed with both alarms and accessories
