IMPORTANT SAFETY INFORMATION

Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with dry cloth.
Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat.
Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade and the third prong are provided for your safety. If the provided plug does not fit into your outlet consult an electrician for replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles and the point where they exit from the apparatus.
Only use attachments/accessories specified by the manufacturer.
Use only with the cart, stand, tripod, bracket or table specified by the manufacturer or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
Unplug this apparatus during lightning storms or when unused for a long period of time.
Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way. Such as when the power supply cord or plug is damaged, liquid has been spilled, objects have fallen into the apparatus or the apparatus has been exposed to rain or moisture and does not operate normally or has been dropped.

INSTALLATION

Mounting

The EZ-GW24 is designed for rack mounting (1U).

Confirm mounting brackets are firmly attached to the EZ-GW24. Place the EZ-GW24 into a standard 19” rack and secure to rack with proper hardware. (Figure 2)

Power Connections
Make sure all signal connections via the back panel are made and the EZ-GW24 is connected to the Ethernet switch, then connect the power cord to the AC power source. A strain relief bracket is provided to secure the AC cord. (Figure 4)

Front Panel Connections (Figure 5)

Network Connection

The EZ-GW24 has an RJ45 Ethernet network connection on the front panel.
The Ethernet connector has two LEDs to indicate link speed and activity.
- Left LED (Amber) indicates Activity: Flashing indicates packets sent/received
- Right LED (Green) indicates link: On steady: Connected

Status LED
The Status LED on the front panel indicates the general status of the EZ-GW24. (Figure 5)

Off: Indicates system startup or not powered on
Red Flashing: Indicates system is ready

SPEAKER CABLING

If this EZ-GW24 is installed to replace an existing page controller, please be aware the primary cause of troubles in retrofit systems is directly related to the existing field wiring.
It is imperative that existing speaker wiring (field wiring) be assessed before making connections to new equipment.
Always check speaker lines, new or existing, for transient voltage and proper impedance before cross connecting to the intercom equipment. Use a good quality Impedance Meter, not an Ohm meter.

The speaker type is selected in the software during programming, with the choices of 25 Volt, 45 Ohm or Line Level. All speakers must be of the same type and must not exceed the following limits:

45 Ohm Maximum of 5 Valcom 45 Ohm speakers per zone with no more than 24 across all zones
25 Volt Total tap of 15 watts per zone with no more than 120 watts across all zones

One-Way Line Level Maximum of 45 Valcom self-amplified speakers per zone and no more than 240 self-amplified speakers across all zones

Rear Panel Connections (Figure 1)
Speaker Zones 1 – 24 are individual connectors for speaker output. A wiring connection block with screw terminals is provided for each zone. The individual screw terminal blocks may be removed for easy installation. Each block has connections for two zones, with arrows indicating which zone is the top row and which is the bottom row. The connections labeled “SW” are not used. Details of the wiring connections are shown below.

A strain relief bracket is provided to support the speaker wiring. The bracket must be attached to the rear of the EZ-GW24 by removing the two case screws on each end of the unit, positioning the bracket against the case, and reinstalling the screws. (Figure 3)

Setup

Information specific to your application will need to be programmed into the EZ-GW24 using a computer. The PC used for programming should be connected to the same subnet as the EZ-GW24. Setup will be done using the IP Solutions Setup
Tool. Download the latest version of the free IP Solutions Setup Tool from the Valcom website at www.valcom.com/vipsetuptool.

Factory Reset Modes

A button is provided through a pinhole in the front of the EZ-GW24, beside the Status LED, that can be used to reset the EZ-GW24 configuration. Pressing the button continuously for 10 to 20 seconds will perform a soft reset on the EZ-GW24.
The IP address will be reset to factory default. Other configuration items will not be affected.

If the button is pressed for more than 20 seconds, all configuration items will be reset to factory default, including the password. (Figure 5)
