2.0 Unit Installation

Before proceeding with the mounting and wiring of the EntraGuard Bronze system, verify your
mounting plans will meet all applicable Local, State, and Federal ADA mounting height and
accessibility building codes. Also verify you have a safe and secure path for routing all wiring.

2.1 Mounting Location

Locate the unit as near as possible to the controlled gate. Although the unit is resistant to
environmental factors, it should be protected from direct rain and snow.

The unit has four mounting holes for pedestal mounting and two wiring knock-outs, one on the back
of the enclosure and one on the bottom (see Figure 1 on page 2). For wall mounting, choose a rigid
wall. For pedestal or fence mounting, provide enough bracing so the unit will not be subjected to
excessive shock or vibration when the gate is opened.

Due to the nature of this unit’s use, the unit may experience abuse and vandalism. Unit mounting
must be done in such a way as to minimize the effects of such treatment.

Typical mounting hardware is #10 x 1 1/2 inch wood screws into wall studs or 3/16 inch fasteners
into masonry. Provide additional framing or a backing plate when mounting the unit to paneled or
dry-walled areas. The more secure the unit location and mounting, the greater the level of on-going
unit integrity.

2.2.1 Earth Ground

For safety and for EMI noise reduction reasons, the EntraGuard Bronze’s enclosure must be earth
grounded. Using a ground wire, connect the unit’s enclosure to a known earth ground (such as a
ground rod or a conductive cold water pipe), observing all applicable codes.

2.2.2 Power

The EntraGuard Bronze uses a 20 VA plug-in transformer which must be plugged into an
unswitched (always ON), standard 120 VAC wall outlet. For best operating conditions:

• The outlet should be free from any other loads (preventing power fluctuations from affecting the
unit).

• Locate the outlet/transformer as close as possible to the unit.

• Ensure the transformer will not be accidentally unplugged from the outlet.

If the transformer cable length is not sufficient to reach from outlet to unit, additional cable can be
added. To ensure proper voltage and current at the unit, Table 1 lists the wire gauge to use based on

2.2.3 Phone Line

The EntraGuard Bronze does not require a separate control unit or second phone line. It is wired in
series with the incoming telephone service (Figure 3 on page 5). Using standard two-conductor
telephone cable and RJ-11 plugs, connect the incoming phone service to the J1-CO jack (Central
Office) on the EntraGuard Bronze PCB (see Figure 2 on page 3). Then connect the residential
phone system to the J3-Phone jack.

In applications where the residential phone system has multiple phone lines, only one incoming
telephone line can be designated as the telephone entry line, run through the EntraGuard Bronze
unit.

NOTE: Telephone wiring must be done to telephone industry standards to ensure the TIP and Ring
lines are correctly connected. If these lines are not correctly connected, the unit will not operate
properly.

2.2.3.1 Intercom Jumper

The EntraGuard Bronze has a jumper that, when in place, turns the phone and Bronze connection
into an intercom without the need of an external phone line.

CAUTION: When the jumper is in place, the phone connected to the Bronze will not be able

to dial anything other than the Bronze unit. This also means that call forwarding will not work.

Make sure the phone line from the telephone is connected to the J3-Phone jack on the Bronze. Then,
to make the phone and EntraGuard Bronze act as an intercom without use of an external line, take
the jumper connector (provided in a separate plastic bag) and place it over the two pins of JP1 (see
Figure 2 on page 3). When the jumper is in place, the unit will act as a separate intercom with no
connection to external phone lines. Use this jumper with care. Even if an external line is

connected to the Bronze, the jumper in place will prevent the phone from dialing any outside
line.

2.2.4 Relays

There are two relays in the unit. Each relay can control a gate and each relay is activated by a
command from either the residence telephone or from the unit itself. Make the wiring connections
from the unit to your gate controller as are appropriate for the panel’s needs. Typically, a two­conductor, AWG 22 wire is sufficient, however a heavier gauge of wire may be required depending
upon the current demands of the gate controller panel and the wire run length. See Figure 2 on
page 3 for relay pinouts.

2.2.4.1 Isolation Relay for Transient Protection

Some gate controllers generate transients whenever the gate is opened (typically caused by the
starting of the gate motor when opening or closing the gate). These transients can be sent down the
relay lines to the EntraGuard Bronze unit, affecting unit operation. To guard against transients, a
Keri Systems IRP-1 can be installed on the relay line, isolating the unit from the gate controller. See
Figure 5 on page 7 for a wiring diagram.

2.3 Telephone Bypass Module

The telephone bypass module may be installed so that in the event of a short in the EntraGuard
Bronze wiring, the EntraGuard Bronze unit may be bypassed, allowing the house phone to function
as normal. The Telephone Bypass Module (Keri Systems P/N 05608-001) must be purchased
separately from the EntraGuard Bronze.

1. Connect the bypass module’s EARTH GROUND terminal to a good earth ground.

2. Before connecting the incoming telephone line to the bypass module, check the polarity of the
wires with a DC voltmeter. Connect the negative wire (RING - usually green) to the bypass
module TELCO RING terminal. Connect the positive wire (TIP - usually red) to the bypass
module TELCO TIP terminal.

3. Connect the resident’s local telephone line RING (usually green) to the bypass module HOUSE
RING. Connect the local telephone line TIP (usually red) to the bypass module HOUSE TIP
terminal.

4. Connect the Bronze Incoming Phone Line RING (J1) to the bypass module RE-1 TELCO RING
terminal. Connect the Bronze Incoming Phone Line TIP (J1) to the bypass module RE-1
TELCO TIP terminal.

5. Connect the Bronze House Phone RING (J3) to the bypass module RE-1 HOUSE RING
terminal. Connect the Bronze House Phone TIP (J3) to the bypass module RE-1 HOUSE TIP
terminal.

2.4 Volume Control

The unit’s speaker volume can be adjusted via the Volume Control potentiometer on the circuit
board (Figure 2 on page 3). Rotate this potentiometer clockwise to increase volume.

NOTE: The microphone gain is pre-set and cannot be changed. This is done to minimize the chance
of feedback between microphone and speaker affecting system operation.

3.0 Standard Operation

There are six standard operating modes used by the EntraGuard Bronze telephone entry system.

• Visitor Call – when an arriving visitor requests entry.

• Call Waiting – if you are already on the telephone when a visitor entry request is made.

• Call Forwarding – designating a telephone number to which an entry request is routed when you
know you will not be home.

• Remote Connection – allows you to connect to the EntraGuard Bronze unit from the residence
telephone and either program or remotely operate the unit.

• Gate Operation from the EntraGuard Bronze Unit – allows you to directly operate a gate from
the EntraGuard Bronze.

• Gate Operation from the Residence Telephone – allows you to directly operate a gate from the
residence telephone.

The enabling/disabling of operation modes and the setting of operating parameters is described in
Section 5.0 beginning on page 13.

Quick Start GuideTelephone Entry

3.1 Visitor Call

The Visitor Call command allows an arriving visitor to request entry by calling the residence
telephone through the EntraGuard Bronze unit.

1. An arriving visitor notifies the residence by pressing the “Call” key.

2. The residence telephone rings with the programmed ring pattern and number of rings.

3. When the residence telephone is answered, it connects to the EntraGuard Bronze unit and
conversation can begin.

4. The connection is automatically disconnected after a programmed amount of time (the default
time is 1 minute). The unit sounds a brief tone to warn both parties with a 3 second warning of
the impending disconnection.

5. The connection time can be extended on the residence telephone by pressing the key.

6. Communication can be terminated immediately and entry denied at any time by pressing the

key.

7. Communication can be terminated immediately and entry granted (by opening the gate) by
entering the desired gate activation code on the residence telephone keypad. When the code is
entered, communication with the unit is terminated and the desired gate relay is activated for the
programmed amount of time.

EXAMPLE: When connected, enter the following to open Gate 1 (assuming the activation code for
Gate 1 is “9”).
