1 Safety

Warning!

Suspending any object is potentially dangerous and should only be attempted by individuals

who have a thorough knowledge of the techniques and regulations of suspending objects

overhead. Electro-Voice strongly recommends that loudspeakers be suspended taking into

account all current national, federal, state, and local laws and regulations. It is the

responsibility of the installer to ensure all loudspeakers are safely installed in accordance

with all such requirements. When loudspeakers are suspended, Electro-Voice strongly

recommends the system be inspected at least once per year or as laws and regulations

require. If any sign of weakness or damage is detected, remedial action should be taken

immediately. The user is responsible for making sure the wall, ceiling, or structure is capable

of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker

not associated with Electro-Voice is the responsibility of others.

Safety point

As an added safety measure, it is strongly recommended to utilize a properly rated secondary

safety cable (provided by the installer) to securely fasten the speaker from the safety point on

its back to a secondary mounting structure on the building.

The compact EVID™ 4.2 delivers very full range sound from its dual 4-inch LF drivers and a 1-

inch titanium tweeter with waveguide. It is able to deliver a 110-dB sound level over a wide

coverage area. The EVID™ 4.2T includes a multi-tap transformer for 70V or 100V line

distribution systems.

EVID™ 6.2 models

The EVID™ 6.2 is an extended-range high-output loudspeaker with dual 6.5-inch woofers and a

1-inch titanium tweeter with waveguide, designed for high SPL over a wide coverage area. The

EVID™ 6.2T includes a multi-tap transformer for a 70V or 100V line distribution system.

2.4 Accessories

SAM™ (Strong-Arm-Mount™) System

EVID™’s SAM™ system (Strong-Arm- Mount™) excels at meeting the four requirements for

mounting FGM/BGM systems: simple, quick, versatile, and reliable.

Three easy steps and you are done:

1. Attach the surface bracket to the wall or ceiling.

2. Attach the EVID™ enclosure to the bracket with the sockethead bolt.

3. Aim the enclosure and tighten the bolt.

8en | Introduction EVID Surface-mount loudspeakers

2023-07 | 04 | F.01U.177.642 Installation manual Bosch Security Systems, LCC

SAM™ allows greater flexibility for aiming than ball-type mounts that limit range of motion

when not on center. Typical ball designs have limited rotation when pointing straight ahead,

and even that is reduced when the enclosure contacts the wall and is moved off axis. By

contrast, SAM™ allows full rotation even at full sweep.

SAM™’s range of rotation is 90°. EVID™’s curved cabinet allows it to rotate much further than a

rectangular or trapezoidal box).

90°

Figure2.3: Rotation range (90°)

SAM™’s range of sweep motion left and right on the wall is 100° for all models.

3 Installation

3.1 Mounting the SAM bracket to the wall or ceiling

Before you mount the SAMTM bracket to the wall or ceiling:

4Determine whether you want to mount the bracket on the left or right side of the speaker

before you bolt the speaker to the bracket.

You can mount the SAM™ bracket on either side of the speaker. This enables optimal

configuration for any installation. It is best to mount the bracket on the side away from the

direction in which the speaker will be aimed. This ensures that the full swing angle is available

for aiming on that side and provides easier access to the swing tightening bolt on the wall

bracket (see Fig. 10, Step 3).

Warning!

Make sure the mounting surface can support more than the speaker's weight. Use only

industry-accepted fasteners and mounting methods when mounting the bracket. Consult an

expert if you are not sure.

For standard vertical installation, mount the SAM™ bracket on the side.

SAM™

Figure3.1: SAMTM mounted on side

For horizontal mounting configurations, mount the bracket on the bottom side. It is easiest

and safest, and allows mounting the speaker closer to the ceiling.

3.2 Selecting the wattage tap

This instruction is applicable to EVID 4.2T , EVID 4.2TW , EVID 6.2T , and EVID 6.2TW models

only.

Before mounting the speaker to the bracket:

4Select the proper wattage tap setting for your installation.

The wattage selector switch is located at the rear of the speaker below the input terminal

panel. A guide on the back of each speaker shows which switch positions to use for the power

settings at 70V and 100V.

EVID 4.2T and

EVID 4.2TW

The power taps are 30W, 15W and 7.5W at both 70.7V and 100V, with a 3.7W tap for

70.7V only, as well as an 8Ohm transformer bypass setting.

Figure3.3: Tighten socket head bolts

1. Attach the speaker to the SAM™ bracket with bolt B.

2. Adjust the horizontal position of the speaker.

3. Tighten the locking bolt A with an Allen wrench (supplied).

If available, use an Allen wrench with a longer handle to make it easier to apply the

necessary force to achieve the recommended torque. Refer to Recommended torque

settings for bolts A and B.

4. Adjust the vertical angle of the speaker.

5. Tighten the locking bolt B with an Allen wrench (supplied).

If available, use an Allen wrench with a longer handle to make it easier to apply the

necessary force to achieve the recommended torque. Refer to Recommended torque

settings for bolts A and B.
