• Fail Safe - Gate unlocks in the event of power loss. The gate will relock when power is reapplied. All magnetic locks
are Fail Safe. Fail Safe electric strike locks are available as an option.
•Fail Lock - Gate remains locked when power is removed (or lost). The gate will unlock only when both power and
an activation contact are supplied. All electric strike locks are Fail Lock unless otherwise specied.
Magnetic Locks are not available in Fail Lock mode.
• Activation - Alvarado's gates require the use of a timed contact switch to lock and unlock. The gate will not
re-engage until the switch is released and the gate is closed.
•Mesh Inll - The mesh inll is a diamond pattern steel mesh that is attached to the interior portion of the gate. The
purpose is to prevent persons from reaching through the gate. This component is available for all
models.
•Microswitch Push Bar - This is an electrically operated mechanical push bar . If there is power loss, the bar will
default to the condition specied for the lock in use. This component is not available for the
MSG or MSG-1 models.
•Mechanical Push Bar - Mounted on the exit side, when the bar is pushed in the exit direction, the latching bolt is
mechanically retracted allowing the user to exit. This allows emergency exiting at any time
through the gate regardless of power conditions. This option is available only on: MSG-1,
MSGX-E, and MSGX-S models.
• Dead Bolt Lock - A keyed lockset that is used to lock the gate in a closed position. A key is required to unlock the
gate on either the entry or exit side of the gate.
•Magnetic Lock - Magnetic lock o󰀨ers up to 1200 pounds of holding force. Power (low-voltage 12VDC) is supplied
to the lock to energize the magnetic lock. When the gate is closed, the latch plate (mounted to
the gate) is held against the magnetic lock (mounted on the gate frame) when power is applied.
The gate is unlocked by removing power from the magnetic lock and the patron pulls the gate
open in the entry direction or pushes the gate open in the exit direction. This is standard only on
the MSGX and MSGX-PX models.
•Electric Strike Lock - A lock where power (low-voltage 12VDC) is supplied to the lock to release the mechanism to
allow the gate to open. Power is then removed to allow the strike to be in the lock position.
This lock is standard on the MSGX-E and MSGX-S models.
• Universal Card Reader Mounting Plate - A mounting plate is attached to the latch post of the gate on the entry,
exit, or both sides.The mounting plate is a universal style plate that an
additional device specic plate may be added in order to t the reader that
is required. This option is available on: MSGX, MSGX-PX, MSGX-E, and
MSGX-S models.
•Push-To-Exit Remote Button Switch - A 3.15in square switch box assembly constructed of stainless steel with a
DPDT (double pole double throw) push button switch. The switch is eld
wired into the strike or magnetic lock power cable to unlock the gate from
a remote position such as a guard shack. This optional component
is available for: MSGX, MSGX-PX, MSGX-E, and MSGX-S models.
• Magnetic Sensor Switch - A two piece switch magnet mounted on the gate and the latch post. It is used to monitor

Anchoring Instructions
1) The hydraulic arm is detached from the gate for
ease of shipping. Before removing the gate the from
the shipping crate, reattach the hydraulic arm hinge
to the gate using (2) 1/4" machine screws. [Figure 3].
2) Determine the installation location of the gate, taking
into consideration the minimum width opening
required; refer to Drawings & Dimensions section
on Pg. 7 for minimum installation requirements.
Once the installation location is conrmed, snap a
chalk line on the oor to mark the centerline of the
gate. The chalked centerline should be at least 6"
longer than the overall width of the gate.
3) Set the gate on the chalk line, facing in the correct
direction of operation.
4) Mark the center locations of the (4) four anchor holes
in each of the frame's base plates.
5) Move the gate to the side and drill a 5/8" diameter
hole to a depth of 3" at the center of each marked
location. For terrazo, ceramic tile, or brick veneer
installations, add the thickness of the nished oor
material to anchor the hole depth.
6) Vacuum out the holes thoroughly. If the holes are not
clean, the anchors will not tighten.
7) Insert one anchor into each drilled hole. Ensure
the anchors are ush with the concrete oor or
nished surface and the threads are down as shown
in [Figure 4].
NOTE
It is recommended to brace the top of the gate with supplemental products or with exisiting structure to increase
rigidity and support.
CAUTION
Care must be exercised when moving the gate
The gate weighs approximately 400lbs. Until
the gate is securely fastened to the concrete
foundation, secure the gate / frame assembly
to prevent the unit from falling.

Hydraulic Closing Arm Adjustment Instructions
1. Unscrew the two (2) screws on the top of the plastic cover and remove the cover to gain access to the hydraulic
closing arm.
2. The following adjustments can be made:
•Power Adjustment Nut - Adjusts the closing power of the mechanism using an 11/16" wrench or socket.
To increase power, turn the power adjustment nut clockwise for a maximum of 15 turns. The closing arm is
default setting is 7 turns. The adjustment nut is located at the end tip of the closing arm. [Figure 11a]
•Latch Adjustment Valve - Adjust the speed at which the door closes within the last 10 degrees of motion using
a 1/8" hex key. Turn clockwise for slower speeds, and turn counterclockwise for faster speeds. The valve is
located on the side of the closing arm and is labeled with the letter "L". [Figure 11b]
•Sweep Adjustment Valve - Adjust the speed at which the door closes in the rst 80 degrees of
motion using a 1/8" hex key. Turn clockwise for slower speeds, and counterclockwise for faster speeds.
The valve is located on the side of the closing arm and is labeled with "S/D". [Figure 11b]
•Backcheck Position Adjustment Valve - Adjusts the door angle where backcheck cushioning starts with
a 1/8" hex key and is shipped with the valve normally closed. Turn counterclockwise to increase the angle.
The valve is located on the side of the closing arm and is labeled with the letter "P". [Figure 11b]
•Backcheck Adjustment Valve - Adjusts the hydraulic resistance to door opening with

MSG Installation and Maintenance Instructions
Maintenance
The frequency of interior maintenance will depend how often the gate is used, the type of personnel using the gate, and
the environment the gate is installed in. The gate should be inspected during the rst 30 days after installation. Follow
the maintenance schedule below after the rst 30 days. This schedule is based on what's called a "typical installation"
- which is a temperate climate where weekly use is up to 300 activations. If use exceeds this threshold, personel are
abusive to the gates, or if the gates are installed in harsh environments, such as coastal areas, chemcial or renery
plants, very hot or cold locations, or extremely dusty environments, consider increasing the frequency of maintenance
to a level suitable for your application.
Operational Care
General - Check gate levelness and the tension of the anchors. Tighten to approximately 25 ft-lbs. Clean away
accumulated dust and dirt.
Wiring - Inspect all wires and contacts for any signs of wear, abrasions, or exposure to any metal parts that may
lead to a short.
Hinges - Lubricate the door hinge points with 3-in-1 oil and verify that the gate door moves and self closes freely.
Closure - Lubricate the closure hinge points with 3-in-1 oil and verify that the gate door moves and self closes freely.
Gate Finish Care
The nish on your gate will look better if it is maintaned. The frequency of maintenance depends on three factors:
1. the installation location, 2. environmental factors, and 3. the customers interest in how the gate looks. We suggest
cleaning the exterior of the gate every three (3) months.
Hot Dipped Galvanized Finishes -
A hot dipped galvanised nish is an industrial coating designed to provide corrosion protection. Aesthetic
considerations are secondary. Finish irregularities are a natural result of the hot dipped galvanizing process. The
apperance of a hot dipped galvanized coating can vary depending on the size and shape of the coated object. Various
apperances for hot dipped galvanized steel (all acceptable under appropriate ASTM standards) include bright and
shiny, spangled or mottled, matte gray, or a combination of various conditions. In most instances, the apperance of hot
dipped galvanized material has no e󰀨ect on the primary purpose of the nish (corrosion protection) and over time and
exposure to the environment, all galvanized nishes will take on a uniform matte gray apperance.
Periodic cleaning of galvanized nishes is recommended. To clean galvanized nishes, use a neutral (non-alkaline)
detergent, such as a car shampoo, clean warm water and a soft brush. Abrasive cleaners, steel wool, and chemical
cleaning products should not be used. Rinse the surface after cleaning.
Damaged galvanized areas can be treated or touched up with zinc-rich paint. Use an organic cold galvanizing
compound following the manufacturer's instructions. An explanatory document describing the ASTM recommended
repair process is available from the American Galvanizer Association website.

Gate Finish Care (Cont.)
Stainless Steel Finishes:
Stainless steel is a corrosion resistant chromium/nickel alloy steel that is strong and durable. However, it is not
rustproof, particularly in harsh environments. In addition to actual damage, stainless steel can appear to rust when
contaminated through contact with carbon steel. This contact can come from tools, adjacent mild steel, fasteners,
particulate, or through contact with hard water (which can leave spotting and staining on stainless steel). The most
common method of contamination in windy, dusty, and/or industrial environments in the form of steel and mineral
particles that "land" on the stainless material. Mild steel naturally adheres to a stainless steel surface (due to iron-to-
iron a󰀩nity). Grained material and welds are common areas where foreign particles become trapped. In these cases,
it is generally the steel residue, not the stainless steel material itself, which rusts initially. If left untreated, however,
damage to the stainless steel surface itself can occur.
Regular cleaning is the best way to maintain any stainless steel nish. The goal of a cleaning program should be to
clean the surface, keeping the stainless steel's protective chromium oxide layer intact. The frequency of cleaning will
depend on the environment.
Regular cleaning can be accomplished by rinsing the stainless steel surface with fresh water to wash away
accumulated chemicals, materials and particulates. Wipe dry with a clean cloth. Clean equipment immediately after
coming in contact with chlorides (chlorine powder, salt melt, seawater, etc.).
For embedded deposits, use a neutral detergent, such as a car shampoo, clean warm water, and a soft brush. Rinse
the surface after cleaning. Never use steel wool. MAAS makes an excellent stainless steel cleaner in spray form,
MAAS Stainless Steel & Chrome Cleaner, available from the MAAS website (www.maasinc.com). All products listed
can also be used for general cleaning.
For stubborn stains, heavy spotting, and rust, our recommendation is MAAS Metal Polish (in liquid form). Follow the
manufacturer's directions but in brief: 1. wipe down excess dirt from the gate, 2. apply polish to the metal, 3. polish in
the direction of the grain with a super ne (0000) or ne (000) synthetic steel wool (depending on the level of tarnish),
4. wipe clean, 5. repeat steps 2 - 4 until clean. Again, never use steel wool.
Highly damaged areas may require chemical passivation. To chemically passivate stainless steel, Alvarado
recommends the use of a citric acid product, CitriSurf2310. This product is formulated to clean and passivate stainless
steel and can be used in the eld.
Even with periodic cleaning, it is possible that periodic chemcial passivation will be required to maintain stainless steel
in especially harsh environments.
Powder Coat Over Galvanized Finishes:
To clean the powder coat nish, use a neutral detergent, such as car shampoo, and rinse with clean water. In the
event that the powder coat nish is chipped and bare metal is showing, seal the area as soon as possible, If the area
is not sealed, the underlaying metal will rust, which could eat away the powder coat and cause aking. Touch up paint
is also available from Alvarado.
