FUNCTION DESCRIPTION
3880EL - Fail Safe Control
Outside trim is locked when power is applied and unlocked when power is removed (storeroom function when energized). Lockset
will unlock in the event of a power failure.
3880EU - Fail Secure Control
Outside trim is unlocked when power is applied and locked when power is removed. Lockset will lock in the event of a power
failure. This is the default lock setup.
Note: 3882 will function the same as the 3880EL / EU, but both sides will lock/unlock simultaneously.
Key Function
When key cylinders are installed into locks, the latch bolt may be momentarily retracted from the outside with key even if lockset is
electrically locked.
Latch Bolt Monitoring
Latch Bolt Monitoring (LM) is a SPDT switch that is mounted inside the lockset. The LM switch monitors the full extension of the
main latch.
Request to Exit
Request to Exit (RX) is a SPDT switch that is mounted inside the lockset. The RX switch monitors the activation of the inside trim
when the lockset is in the locked position only.
Door Position Monitoring (DPM)
Door Position Monitoring is a SPDT magnetic reed switch that is mounted in lock body and reacts with a magnet in the strike to
monitor if the door is in the closed position.

The Hager 3800 Series Electric Mortise Lock is a sophisticated locking mechanism designed for various access control applications, offering both fail-safe and fail-secure configurations, along with integrated monitoring capabilities.

Function Description:

The core functionality revolves around two primary control modes:

• 3880EL - Fail Safe Control: In this configuration, the outside trim is locked when power is applied and unlocked when power is removed. This means that in the event of a power failure, the lockset will automatically unlock, providing a fail-safe exit. This is often used in applications where egress during an emergency is paramount.
• 3880EU - Fail Secure Control: This is the default setup for the lock. The outside trim is unlocked when power is applied and locked when power is removed. Consequently, if there is a power failure, the lockset will remain locked, ensuring security.
• 3882 Model: This model functions similarly to the 3880EL/EU, but with the added feature that both the inside and outside trims will lock/unlock simultaneously.

Key Function:

Even when the lockset is electrically locked, the key cylinders allow for momentary retraction of the latch bolt from the outside using a key. This provides a mechanical override for access.

Monitoring Capabilities:

The lock incorporates several monitoring features to enhance security and system integration:

• Latch Bolt Monitoring (LM): A SPDT (Single-Pole, Double-Throw) mechanical switch located inside the lockset. It monitors the full extension of the main latch bolt, providing feedback on its position.
• Request to Exit (RX): Also a SPDT mechanical switch, the RX monitors the activation of the inside trim. This is active only when the lockset is in the locked position, signaling an attempt to exit.
• Door Position Monitoring (DPM): A SPDT magnetic reed switch integrated into the lock body. It interacts with a magnet in the strike plate to detect whether the door is in the closed position.

Important Technical Specifications:

EL and EU (Motorized Locking/Unlocking):

• Operation: 12/24V AC/DC (11V – 30V)
• Current Consumption:
  • Maximum Inrush: 250 mA
  • Maximum Holding: 10 mA
• Leads: Non-polarized
• Default State: Fail Secure

  • Red Wire: Open Loop Secure
  • Green Wire: Closed Loop Secure

Usage Features:

Electrically Locked (EL) / Electrically Unlocked (EU) Configuration:

The unit is shipped as Fail-Secure (EU) by default. To change to Fail-Safe (EL), a white switch slider inside the lockset must be moved from the YELLOW position to the GREEN position. It's crucial to apply power at least once after changing the switch state for the lockset to adopt the new configuration. The colors (YELLOW/GREEN) indicate the direction to move the switch, not its current position. The switch should move easily without force.

Door Position Monitoring (DPM) Installation:

The DPM's magnetic reed switch is mounted within the lockset, while its activation magnet is positioned behind the ANSI strike plate. Proper orientation of the magnet plate is essential for correct positioning relative to the latch bolt, ensuring accurate door position monitoring. Diagrams are provided for both left-hand and right-hand strike plate orientations.

Wire Bundles:

The lock utilizes various wire bundles depending on the ordered functions. Users should refer to the wire color within each bundle to identify the specific function, as detailed in the technical specifications.

Quick Connects:

The mortise lock electrification options feature quick connects for easy and accurate wiring. These are compatible with Hager Quick Connect Harness Cables (sold separately), which can be plugged into Hager hinges equipped with quick connects. This system simplifies installation and reduces wiring errors. Detailed pinning information is provided for both 8-pin and 4-pin quick connectors, specifying the function and corresponding wire color for each pin (e.g., Power, RX, DPM, LM).

Maintenance Features:

Door and Frame Preparations:

• Mortise Pocket: The mortise pocket in the door and frame requires an additional 1/2" depth beyond standard mortise lock preparations. Since the motor control is integrated within the lockset, no other special preparations or alterations are needed for the standard installation.
• Door Raceway: A raceway through the door is necessary to route electrical wires. A 3/8" diameter raceway is recommended. However, if quick connectors are used, a 5/8" diameter raceway is required to accommodate their insertion. Door fabricators are responsible for providing this raceway.

The Hager 3800 Series Electric Mortise Lock is a robust and versatile solution for controlled access, offering flexible configurations, comprehensive monitoring, and streamlined installation through its quick-connect system.
