OPERATION:
All 50HBM locks are operated by electric motor. The choice of three motor operations provides a variety of functions:

FULL-ROTATION MOTOR
(50HBM)
With latchback (1), 01:
Unlocks when the motor is energized by a momentary contact switch. Once unlocked, the hookbolt is held mechanically in the raised position until the door is opened. It then returns to normal, lowered position.

TWO-POSITION MOTOR
(50HBMC)
Without latchback (2), 04:
Same as above, except that the hookbolt is raised and lowered as the motor runs. A door starter should be installed in the track housing to push the door open when the motor reaches the unlocking point.

TESTING:
50HBM locks have been tested in Folger Adam Security Inc. facilities for over one million operations

STANDARD FEATURES:

• Motor voltage - 120VAC
• External mounting - Locks install without cover plate removal. External slotted mounting holes simplify installation, and allow for variations in door gap by permitting lateral movement.
• Two-piece plug connector - Simplifies wiring at time of installation, and allows pre-wiring at the lock pocket.
• Superior durability - Working parts are stainless steel and designed for maximum strength, and corrosion resistance.
• Hardened hookbolt and deadlock actuator - Galvanized for corrosion resistance.
• Motor operation - A choice of three operations is available.
• Choice of five or six lever tumbler models.
• Mechanical unlocking by key - Once unlocked by key, the hookbolt remains in that position until relocked by key (Models without latchback feature). Key is removable in the unlocked position.
• Indication switch - The indication switch monitors the deadlock lever a for indicating a deadlocked hookbolt.

OPTIONAL FEATURES:

• Motor voltage - 24DC
• Lock bolt keepers - Select 50H-4DB with dust box

STANDARD COMPLIANCE:
All series120M locks are UL1034: Burglary-Resistant Mechanisms, and some are UL10B listed as
Fire Door Accesories to a three-hour rating. Key holdback models are not UL10B listed.
Maxi-Mogul Key Cylinders meet UL437 requirements.

OPTIONAL FEATURES
Faceplate- For applications requiring a finished faceplate, specify US4, US10, US10B,
US32, or US32D
Indication/auxiliary switches- An indication switch monitors the deadlock lever indicating
a deadlocked latchbolt. The auxiliary switch monitors the latchbolt for extended or retracted postion.
Local electric key (LEK)- A unique function which uses two types of keys. One key turns in one direction only, and operates the lock electrically. The supervisory key turns in both directions to operate the lock electrically or mechanically. The electric operation may be cancelled from a central console or control point at any time via a three-position switch. For applications where inmates carry their own keys, but supervision is necessary. The Maxi-Mogul Key Cylinder is uniquely suited for this high frequency operation, shown by cylcle test of 1,000,000 operations.
Galvanized case and cover- For exterior applications.
Key Cylinder Extension- When the lock is keyed on the stop side of the jamb, an extension eliminates the need for a special, recessed frame pocket.

TWO-POSITION MOTOR ACTUATED MODELS:
Lock or unlock when the motor is energized (1): by either a two or three position maintained contact switch, or three position, momentary contact switch. When unlocked by control switch, latchbolt remains retracted by motor position until control switch is set to lock. Latchbolt is held mechanically retracted until the door is opened. It will then extend automatically, if the control switch is set to the lock position. (Mechanical Latchback)

Lock or unlock when the motor is energized (2): by either a two or three position maintained contact switch, or a three position momentary contact switch. Latchbolt then remains retracted until selected to lock. Opening and closing the door has no effect on the lock. (No Latchback)

Unlocks when the motor is energized (3): by a momentary contact switch. A relock switch energizes the motor to relock once the door is open. On closure, the latchbolt deadlocks automatically. (No latchback with relock)

STANDARD COMPLIANCE:
All deadlatch models, UL1034: Burglary-Resistant Mechanisms.
All models (except two-position motor actuated), UL10B: Electrically controlled single point locks or latches, three-hour rating, A label.

• Finish - US32D, satin stainless steel.

• Indication switch- An internal switch to monitor the positions of the deadlock actuator. Signals deadlocked condition.
• Note: When door is open, deadlock actuator may be manually depressed, thereby giving a false indication that the door is locked. This can be eliminated by installing a door position switch and wiring it in series with the indication switch in the lock. A "secure" signal can then be produced only after three conditions have been met:
  (1) deadlock actuator is depressed
  (2) deadbolt is extended and deadlocked, and
  (3) door is closed.
• Interlocking of doors requires special wiring and/or adaptations in control consoles.
• Builders hardware key cylinders - High security six pin tumbler cylinder may be specified. Special keying requests will be accommodated, if possible.
• Note: Customer supplied key cylinders may be used to adapt NS400 Series locks to a specific keying system. These cylinders must have:
  a) 1-5/32" diameter, full bar stock bodies,
  b) 1-1/8" length, including cam,
  c) Standard, removable Yale-type cam.
• Cylinders and all keys should be sent to Folger Adam Security Inc. in any case, but are required with LEK feature and cylinder extensions.
• Local electric key (LEK) - Inmate key operates lock electrically, staff keys always operate the lock manually, and can operate it electrically. Feature is enabled or canceled from a remote control console.

Note: When gate is open, the switch actuator for the locking tongue can be manually depressed, thereby giving a false indication that the gate is locked. This can be eliminated, if desired, by installing a gate-position indication switch and wiring it is series with the indication switch in the lock. A "secure" signal can the be produced only after three conditions have been met:
1) locking tongue switch actuator is depressed;
2) deadbolt is extended and deadlocked, and
3) gate is closed.

Note: Electrical interlocking of gates requires special wiring and/or adaptations for control consoles.
