Added Security through Delayed Egress

The Alarm Lock AL#715 is a time-proven solution for situations where a positive latching delayed system is required.

As security and door control grow in popularity, the variety of delayed egress products is also increasing, with many different models to suit a variety of installation environments. Along with the increase in the use of Special Locking Arrangements, the number of building codes addressing these...

Service Call

On our project, the AL#715 system was installed with no outside trim because there is no entry into the area from the outside. If the door was to be opened, the employees did it from within.

The system was keyed to arm/ disarm by the manager's key on an interchangeable core and a separate alarm keypad located next to the door. The manager guarded the key like his job depended on it, so we had to page him and get him to return to the door every time we wanted to perform an 'in-progress' system test.

Additionally the AL#715 was connected to the premises fire alarm. If the fire control panel went into alarm, the AL#715 was set up to cancel the exit delay and unlock immediately if the bar was pressed, for immediate egress. If the bar was not pressed, the door remained locked. This is a good idea, in case someone deliberately initiated an alarm at the FACP or at the door and then left the area to see if anyone responded. If the door were to unlock regardless, this person could then return to the outside of the premises and gain entry.

Normal operation was if someone attempted to egress without first disarming the AL#715, the built in sounder sounded and the alarm system would notify the front desk.

During the service call, we determined that the circuit from the FACP to the alarm lock was in constant alarm condition, and therefore the AL#715 therefore wasn't delaying egress as the system was designed to do. Additionally the required signage was missing from the door.

Before departing, we notified the facilities department of the FACP system trouble and installed the required signage.

We then made follow-up phone calls to the facilities department, and returned to the store when the FACP issue had been resolved to re-attach the FACP and perform a final operational test on the system.

New Installations

Installation of an AL #715 requires four important things:

A customer who will pay you

An AL#715

A system/installation plan

The LAHJ's approval.

Be sure you have the approval of the LAHJ before investing too much time or money in the project. Be certain your door is outswinging and in working condition. A door closer is recommended.

Locate the AC voltage source you will use to power the AL#715, and note what external connections you will need to make.

The control box must be mounted on the wall adjacent to the door, so determine where it is going to be placed. An Alarm Lock armored door loop is provided with the system. The door loop may be mounted at the same height as the AL#715, but it will then be rather vulnerable to damage. The door loop can also be mounted at the top of the door on the hinge side, but then you have to figure out how to get the cable from the AL#715 up to the top of the door. A surface mounted wire mold kit is available form Alarm Lock; you can obtain additional wiremold from your distributor or a home center.

The AL#715 transformer is a plug in type, but it is best to determine whether a duplex receptacle or a hard-wire quad box will be supplied by the client. Plug-in transformer are easy to deal with, but they also can be problematic if the receptacle is subject to tampering and transformer might fall out or be purposely removed. Hard-wired transformers are readily available. If you are not a licensed electrician, it is recommended to have the client arrange for a licensed and insured electrician to deal with this detail of the installation.

If a fire alarm connection is mandated by the LAHJ, make an agreement with the fire alarm contractor as to how this connection is to be performed, when he'll do it, and how you will test the system when you're complete.

Ask your client if outside key control will be required and have the required tools and accessories on hand for the day of the installation. The AL#715 is all surface mounted, but the locking mechanism is somewhat unique. You may wish to review the installation instructions and examine the #715 unit before throwing it on the truck and heading out to the installation site.
