Keri Systems EntraGuard Bronze Quick Reference - Manual

P/N 01811-001 Rev. B
EntraGuard Bronze Quick Reference
This Quick Reference is designed for the experienced installer as a quick reference while
installing to ensure all connections are made properly. The EntraGuard Bronze has been pre-
programmed. Refer to the EntraGuard Bronze Residence Guide (P/N 01911-003) for the
programming code and other pre-programmed information.
The Quick Reference is designed as a checklist of sorts where you may check off as each
installation procedure is completed. Additional information is given for those who need to be
reminded of what is performed during that part of the installation. For detailed information on
installing the EntraGuard Bronze Telephone Entry Controller, see the EntraGuard Bronze Quick
Start Guide (P/N 01911-001).

height and accessibility building codes. Also verify you have a safe and secure path for routing
all wiring.
Figure 1: EntraGuard Bronze Mountin Holes and Wiring Knock-Out
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). 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.
2.0 Cable Requirements
Telephone
• 2 pair copper phone line with RJ11 connection (one going to the unit and one
returning to the house)
NOTE: EntraGuard Gold is not to be used with a Centrex, PBX, or digital phone line. Only use
a Plain Old Telephone Service (POTS) analog phone line.
Input Power
• two conductor, stranded, AWG 18 wire (Belden 8461 or a larger gauge)
NOTE: On long power cable runs, the cable resistance causes a drop in voltage at the end of
the cable run.
Earth Ground
• Single conductor, AWG 18 wire (or a larger gauge) - Ground wire is green, with
or without yellow tracer.
Input and Output Connections
• two conductor, stranded, AWG 22 (or a larger gauge)
NOTE: The Lock Output relays may require a heavier gauge of wire depending upon the current
demands of the lock and the length of the lock wiring run.
NOTE: If plenum cable is required, please reference the Belden plenum equivalent to the cables
listed above.
3.0 System Wiring
Refer to Figure 2 for wire connection locations for all instruction in Section 3.2.
Figure 2: Circuit Board Connections
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.
Take a 20 VA plug-in transformer and plug it 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.
3.1 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 two-conductor, 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 3 for relay pinouts.
3.1.1 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 3).

4.0 Resetting the EntraGuard Bronze’s Microprocessor
The EntraGuard Bronze comes with basic features pre-programmed. To reset the
microprocessor (and clear all pre-programmed), perform the following steps.
1. Turn unit power OFF.
2. Press and hold the and keys.
3. Turn unit power ON.
4. Release the and keys.
The unit is now reset.
NOTE: Performing a reset completely erases ALL pre-programming and restores the
EntraGuard Bronze to the factory defaults.
