HORTON AUTOMATIC LOCKING MECHANISM FOR DOOR TRAFFIC CONTROLS:

1. To enable occupants of a building to leave while barring entry in banks, department stores, supermarkets, office buildings, and factories.

2. For security measure in apartment complexes and computer rooms.

3. To allow free movement of authorized personnel of an institution while barring the unauthorized movement of patients and unauthorized personnel.

4. For insurance against personal harm and property damage for late workers in all types of service business.

GENERAL

The Horton sliding door lock is installed in the header as an accessory that is part of the operating mechanism. Switching controls as simple as toggle switches can be utilized at a particular period of the day when TRAFFIC CONTROL is desired or the lock can be used continuously as a means of CONTROLLING ACCESS TO A PARTICULAR AREA.

TRAFFIC CONTROL

By mounting the locking mechanism in the header section of the Horton sliding door (pneumatic or electric operator) entrances and providing a remotely located toggle switch (in a secure area) any normal actuating switching means may be rendered useless (cut out) and the locking mechanism put into action. This is generally the exterior actuating switch (mat or motion detector) that is used through the day. During the evening it may be desired to LIMIT ACCESS from the exterior but allow anyone inside to exit freely through the automatic door. Thus, by the mere flip of a switch public control of the door from the exterior is eliminated. The interior mat or a remotely located switch can be made to unlock and open the doors, then after the adjustable time delay expires the doors will close and lock themselves (See sketches below).

LIMITING ACCESS

On this system the exterior actuating device is a security control switch device such as a key card system. This system is used to signal the operator when to open thus allowing entry to only authorized personnel (see sketch, page 2). Exit from the interior is generally uncontrolled. An actuating device such as a floor mat switch can be placed in front of the door to allow anyone inside to exit.

Normal sliding door use is two way traffic flow.

ONE WAY CONTROLLED TRAFFIC

A remote switch can be used to cut off mat A but allow B to continue to operate.

TWO WAY REMOTE CONTROLLED

Cut off A and B; another remotely located switch can be used to unlock the door and open the automatic door. The door will close after a pre-set time delay.

HOW IT WORKS

1. Locking For Sliding Door Operation

The automatic sliding door lock C2176 (Series 2000 Electric operator) and C716 (Series 1000 Pneumatic operator) is installed in the header for the purpose of locking the sliding door operation.

When the operator receives a signal to open, an unlocking command is also sent to the lock solenoid. The lock solenoid will retract the latch bolt allowing the sliding door to open. The solenoid will continue to be energized until the signal is removed. When the lock solenoid releases, a spring in the latch bolt will extend the bolt. When the door keeper attached to the sliding door passes the latch bolt (1/2 from fully closed), the spring-loaded bolt will retract then return to its normal extended position when the keeper passes to the other side. The door is now secured in the closed position.

As long as power remains to the operator, automatic unlocking is possible. However, the lock is designed to remain locked in the cases of power failure. Should codes require the door to be opened in cases of power failure, SX swing slide doors should be used or if desired the autolock can be supplied to unlock on loss of power. Specify suffix FS on end of lock number if this is desired.

2. Locking For Swing/Slide Doors

Up until this point we have discussed automatic locking of the slide operation only. Many installations that require the sliding door to offer security to an area will also require for safety to life escape for those inside the facility. The swing/slide door (SX) equipped with a C659 or panic hardware and automatic locking of the operator will provide these features. The 6410 Thumb Turn installed on the Horton Type 110 O-SX is included as part of our SA4624 UL exit listing. It is used to manually unlock the C659 lock. The knob type unlocking is approved by most code groups if the number of persons inside the room is less than 50 persons. It is not acceptable in occupancy classifications that require panic hardware. The sliding door unit can be equipped with panic hardware. However, this should be used only in cases that will not permit the thumb turn device. Panic hardware makes the package much more complicated and expensive than the other systems. Placement of a manual door adjacent to the automatic door to serve as the emergency door is usually the best choice.

Note: C659 or panic hardware is normally in the locked position prohibiting swing operation but does not restrict the slide operation.

THE FOLLOWING SHOULD BE CONSIDERED WHEN SPECIFYING THIS TYPE EQUIPMENT

1. Unit Type:

010, 110, 310, and 410 in any package of your choice.

2. Actuating Means

INTERIOR:

a. (Secure Area) A switch is installed inside the room to signal the operator to open. Any type momentary contact switch will work from a mat to a simple push button. If the door includes a re-versing nosing or safety horizontal photoelectric light, specify a cutoff feature to cut these off shortly before the lock engages. This will keep unwanted persons from pushing an object into the reopening device and opening the door. Mats laid directly in front of the door present a security problem if the mat adjacent to the door is not cut off when the door is closed and locked. If mats are to be used you should consider a small mat immediately in front of the door that is cut off when the door is closed but active when the door is open (serving as a hold open). A second mat would be located in front of the hold open mat to serve as the actuating mat.

EXTERIOR:

a. Access Control System

A security control switch located outside the secured area should be used to signal the door to open when entry is desired.

b. Traffic Control System

If security is not required full time an arrangement as shown on page 1 should be specified. During normal times the door will service two-way traffic. When controlled traffic is required a cutoff switch (E114) can be provided to deactivate the exterior actuating device and cut on the automatic locking of the door.

3. Locks

Numerous options are offered to achieve locking to meet the job requirements. Depending on the degree of security desired additional locking may be wanted other than the automatic locking of the slide operation.

SELECT THE TYPE LOCKING DESIRED BY REVIEWING (a) through (e).

a. Automatic Sliding Door Lock

As stated earlier, the Safety To Life Code may require the sliding door to have the emergency breakout feature (SX). If the door is equipped with the feature, the swingout panel is not locked unless you specify some type of locking for the swingout function. Some security is provided from entry without the locking of the breakout panel. It is normally held closed by a ball catch latch that releases when approximately 45 pounds is applied at the interior lock stile of the door. It is rather difficult to get sufficient grip from the exterior to open the door but it can be accomplished with a hook device. If you feel this is adequate security no additional locking will be required. Specifying a self closing device on the swing slide panel will reclose the panel should it be accidentally knocked open when someone is exiting.

b. C659 Swing Slide Door Locking

An Adams Rite Series 1970 bolt locks the swingout (SX) operation of the sliding panel into the top carrier frame. The bolt is extended during normal door operation preventing entry by pulling the door open. A 6410 Thumb Turn is installed on the inside to allow escape by unlocking the flush bolt and pushing the panel out. (Check local codes to see if this method of unlocking in case of emergency is acceptable for the location of the door.)

c. Maximum Security Non-Automatic Locking

Should manual lockup during non-operational times be required a second key operated cylinder with a MS1853AW lock can be installed locking the door to the jamb.

d. Panic Hardware On Swing Slide Door

If the location requires panic hardware, the Type 310 SO-SX unit is required. Panic hardware equal to Von Duprin Series 33 or Adams Rite 8600 vertical rod surface devices are required. It is installed on the sliding panel locking swing operation only. The sidelite is equipped with a hook lock that interlocks to the sliding door when the sliding door is in the closed position.

e. Remote Monitoring

A switch can be provided to signal a remote located monitoring station that the door is in the unlocked position. The switch can be used to sound an Audible alarm if the monitoring station is not desirable. The alarm provides security without direct supervision.

When a remote door monitoring console is used in conjunction with the autolock, an additional feature must be added to the automatic lock. A switch can be added to monitor the lock bolt and door position. Specify suffix M to the following number when the feature is required. The lock will be the same but the hardware will be different. Part numbers: Electric 2000, C2176-1M; Pneumatic 1000, C716-1M.

The control panel can be furnished with the following monitoring signal lights.

1. Door closed and locked. (Green light)

2. Door closed and unlocked. (Red light)

3. Activating switch cutoff to change to one-way, two-way or no traffic movement at the doorway (three position toggle).

4. Door activating switch (push button).

5. Swing slide panel broken out (or swing out sidelite).

(Red light) Red light denotes non-secure situation.

Additional features that can be provided:

On-Off key switch installed at door in lieu of standard toggle switch to control electric power to operator.

The activating device can be any of the following methods:

Free Access: Floor mat switch, motion detector, push button.

Limited Access: Key switch, card reader, radio control, activating from remote console, etc.
