Schlage Electronics 7766 Magnetic Door Position Switch, Surface Mount, Single Pole Double Throw

The 7766 is a magnetic door position switch. It detects whether an opening is open or closed and reports that status back to a control panel, so the access control or alarm system knows the door state. It does not lock, latch, or release anything on its own. If your goal is door-held-open or forced-door monitoring, or simply confirming a door closed behind a card read, this is the part that supplies that signal.

Either. The 7766 is a single pole double throw switch, so the magnet operating gives you both a normally open and a normally closed contact off the same device. You pick the leg that matches what your panel input expects, which matters because supervised alarm inputs and simple monitor inputs often want opposite states. Nothing has to be ordered differently for one or the other.

The Schlage 7766 is a surface mount switch, so the body and the magnet fasten to the face of the frame and the face of the door rather than into bored holes. That makes it the option for retrofits on existing openings, hollow metal you do not want to cut, and hatches or gates where a concealed contact cannot be prepped. The tradeoff is that a surface device is visible and reachable, so on a public-facing opening a concealed contact is the tidier choice.

They solve opposite problems. A position switch such as the Schlage 7766 only reports whether the opening is open or closed to a control panel; it never unlocks anything. A request to exit device tells the panel someone is leaving so the lock releases and the door does not alarm, and that is a separate part, for example the Command Access REXKIT-CL field installable request to exit switch kit for CL180 Series cylindrical locks. Most monitored openings need both.

No, and the two are often confused because both send a dry contact signal to the same panel. The Schlage Electronics 7766 is a magnetic door position switch: it detects the open or closed status of an opening and sends that status to a control panel, so the panel knows the physical position of the door leaf. A request to exit device such as the Command Access REXKIT-CL, a field installable request to exit switch kit for CL180 Series cylindrical locks with SPDT configuration, signals that someone has operated the lock to leave. Turning the inside lever fires the REX contact whether or not the door ever opens, and the door can be pushed open by hand with no REX signal at all. A monitored opening that has to report held-open or forced-open conditions needs the position switch; the REX kit only shuts off the alarm during an authorized egress.

Those are two different jobs and a hands-free entrance normally needs both. The Schlage Electronics 7766 magnetic door position switch reports the open or closed status of the opening to the control panel; it does not initiate anything and nobody interacts with it. To let a user trigger the door without touching it, the actuating device is a separate part, such as the RCI 910TC Series touchless actuator with 433 MHz remote control at 12/24 VDC, or the RCI 913 microwave motion switch using Doppler radar for sterile environments. In a healthcare or lab vestibule the actuator starts the cycle and the position switch confirms the leaf actually opened and closed again.

Yes. Magnetic position switches like the 7766 are used for monitoring door positions, roof hatches, gates and similar openings, because all you need is a magnet on the moving leaf and the switch on the fixed side. The mounting surface has to hold the two halves in consistent alignment when closed, which is the practical limit on a sagging gate or a warped hatch lid.

Yes, in the sense that matters. A dry contact SPDT output like the 7766's is panel agnostic; you land the common and either the normally open or normally closed leg on the panel's monitor input. There is no proprietary protocol or addressing to match, which is why door position switches get mixed across systems in the same building.

No. The Schlage Electronics 7766 covers the monitoring half only, as a surface mount magnetic switch that tells the panel whether the door is open or closed. The push to exit station is a separate wall device the occupant presses, such as the Dortronics 5286 Series push plate exit release with Push to Exit text, the Dortronics 5287 Series heavy duty push button with a 1-1/2 inch wide push plate on a 3 inch wide back plate marked Push to Exit, or the RCI 916 Series tamper resistant push button with a blue handicap logo at 1-3/4 inch. Order the position switch and the exit station as two line items so the opening is complete.

They sit at opposite ends of the same circuit. The Schlage Electronics 7766 is a surface mount magnetic door position switch with a single pole double throw contact, mounted at the opening itself to report whether that door is open or closed. The Locknetics CSW-100 / CSW-200 is a flush mount concealed desk release with an SPDT switch, mounted under a reception counter or desk so a person can release the door on demand. The SPDT contact is common to both, which is why they read alike on a bid sheet, but one is an automatic sensor of door position and the other is a human-operated release. An opening that is both monitored and remotely released usually gets one of each.

The Schlage Electronics 7766 is designed for monitoring door positions, roof hatches and gates, so a magnetic position switch is the correct family of device for those openings as well as for doors. The outdoor rated switches in the same aisle answer a different need: the Dortronics 5277-PZL Series is a weather proof heavy duty touch sensitive piezo push button with a dual color illuminated ring, and the Dortronics WR5276-HD22 Series is a heavy duty water proof switch with a 5/8 inch round stainless entry button. Those are for a person to press at an exterior location. If the requirement is to know whether the gate or hatch is standing open, that stays a position switch job.

The Schlage Electronics 7766 supplies the door status, sending the open or closed condition of the opening to a control panel, and the panel decides what a held-open condition means. If the alarm has to be heard at the door rather than at the head end, the sounder is a separate device, such as the RCI 903 Series audible alert with tamper resistant design rated 80 to 96 dB. Pairing the position switch with a local sounder gives a stand-alone door prop alarm; the position switch alone gives a status contact that something else has to act on.

For status monitoring outdoors, a surface magnetic contact is still the right device class, since the 7766 works by magnet proximity and has no moving parts to seize. Be aware the exposure rating governs the choice on an exterior gate. Where the part being pushed or touched is outdoors, weather rated switches exist for that job, such as the Dortronics 5277-PZL weather proof piezo switch or the Dortronics WR5276-HD22 heavy duty water proof switch with a 5/8 inch round stainless entry button, but those are release actuators, not position monitoring.

One. The 7766 comes as a single model, surface mount, single pole double throw, so there is no handing, no finish selection, and no left or right variant to specify when ordering. Standardizing a building on it is straightforward for that reason.

They sense different things. The Schlage Electronics 7766 is a magnetic switch that reports the position of the door leaf itself. The Cal-Royal 8633-SW is a microwave cell switch in the 8600 Series supplied with single and double gang black faceplates, and the RCI 913 is a microwave motion switch using Doppler radar technology for sterile environments; both detect a person approaching, not the state of the door. A motion sensor will trigger while the door stays shut and will stay silent on a door propped open with nobody nearby, so it cannot substitute where the panel needs true door position.

They are ordered together rather than one instead of the other. The Norton Rixson 503 vestibule switch is an SPDT momentary push switch with a 15 amp rating, and the Norton Rixson 504 is a dual SPDT momentary vestibule switch with a stainless steel face plate; both are pressed to operate the vestibule doors. The Schlage Electronics 7766 is the magnetic switch that tells the control panel whether a leaf is open or closed. On a monitored vestibule the momentary switch drives the sequence and the position switch reports the result, which is why a takeoff for that opening lists both.
