Mag Lock With No Motion Sensor

I have a potential customer who has a glass double door with a mag on it currently. There is no verticle rod mechanism in the door, so I cannot use any sort of paddle. It currently has an exit motion sensor and a push to exit button. This business does not like the motion sensor because inside the door is a heavy traffic area, so the motion sensor is constantly opening the mag, allowing anyone inside. The motion sensor is aimed down about as far as possible. 

 

I know there need to be two forms of exit, but does anyone have another option aside from a motion?


Thanks in advance!

Can you mount a Securitron TSB to the door and wire that to the mag? What is the door and frame contruction?

EDIT: I see you said glass door... is it fully glass?

Do you know what model of sensor they're using?  It might be possible to change the sensor to eliminate the false opens.

Looks like a standard aluminum storefront door. You should easily be able to use a TSB like Sean suggested on this door.

Trunkslammer suggestion while waiting for TSB or a different motion sensor style: White electrical tape over the top part of the sensor, blocking some of the beam from detecting farther out from the door.

Although you mock the value of the level of engineering, masking is a completely valid and respectable way to alter a PIR area boundaries.

If you have the space available, you could use a photoelectric (PE) beam placed so that it provides detection just in front of (within 3" to 6") the door. When someone crosses the beam, the door would unlock. 

PE beams are old-school alarm devices but still have their applications. Alarm versions are manufactured by companies like Optex and Pulnix. There are also PE beams made by companies like Stanley intended for use as safety beams, but could also be used in your application.

Hi, I'd like to know how you made out with this? Also does anyone know which life safety code says there needs to be two forms of exit? Thanks!

RTE requirements are mandated in several 'model' codes, and often in multiple sections. The major citation in access control are listed below:

For the sake of one example, here is IBC 1010.1.9.9 and .10:

1010.1.9.9 Sensor Release of Electrically Locked Egress DoorsSensor release of electric locking systems shall be permitted on doors located in the means of egress in any occupancy except Group H where installed and operated in accordance with all of the following criteria:

  • The sensor shall be installed on the egress side, arranged to detect an occupant approaching the doors, and shall cause the electric locking system to unlock.The electric locks shall be arranged to unlock by a signal from or loss of power to the sensor.Loss of power to the lock or locking system shall automatically unlock the electric locks.The doors shall be arranged to unlock from a manual unlocking device located 40 inches to 48 inches (1016 mm to 1219 mm) vertically above the floor and within 5 feet (1524 mm) of the secured doors. Ready access shall be provided to the manual unlocking device and the device shall be clearly identified by a sign that reads "PUSH TO EXIT." When operated, the manual unlocking device shall result in direct interruption of power to the electric lock—independent of other electronics—and the electric lock shall remain unlocked for not less than 30 seconds.Activation of the building fire alarm system, where provided, shall automatically unlock the electric lock, and the electric lock shall remain unlocked until the fire alarm system has been reset.Activation of the building automatic sprinkler system or fire detection system, where provided, shall automatically unlock the electric lock. The electric lock shall remain unlocked until the fire alarm system has been reset.The door locking system units shall be listed in accordance with UL 294.

    1010.1.9.10 Door Hardware Release of Electrically Locked Egress Doors

  • Door hardware release of electric locking systems shall be permitted on doors in the means of egress in any occupancy except Group H where installed and operated in accordance with all of the following:

  • The door hardware that is affixed to the door leaf has an obvious method of operation that is readily operated under all lighting conditions.The door hardware is capable of being operated with one hand and shall comply with Section 1010.1.9.6.Operation of the door hardware directly interrupts the power to the electric lock and unlocks the door immediately.Loss of power to the electric locking system automatically unlocks the door.Where panic or fire exit hardware is required by Section 1010.1.10, operation of the panic or fire exit hardware also releases the electric lock.The locking system units shall be listed in accordance with UL 294.

Thanks Brian. I actually just saw that you wrote an article on this a few days ago. Thanks.

Depending upon the height, a curtain motion will also work. It has an extremely small window of motion that, when installed correctly on the ceiling, points straight down.

I recently used the Alarm Controls Inc SREX-100, which has a focused IR beam in the area of the door handle. It was a great solution for a single door with a lever handle lockset.

You would probably need two of them, one for each door, focused on the area of the crossbar.

I agree that the TSB would probably be a better solution, unless the customer doesnt want the touchbar and the door cords.

Good point on the aesthetics and TSB. The Curtain motion sounds like a slick alternative if aesthetics was a concern.

Does anyone make a pressure-sensitive mat that can be placed in front of the door, or under the carpet? Kinds like what is used to open a gate for a vehicle exit?

United Security Products still makes them.

Pay no attention to the wording in the link. It will still take you to mats.
