Common Terms
• 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 specied.
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 Inll - The mesh inll 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 specied 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 oers 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 specic 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
whether the gate is open or closed. The switch is a SPST (single pole single throw)
contact supplied with two lead in wires for eld connection. This option is available for all
MSG models.
