MS Sedco 830 Series Combination Keyswitch and Push Plate Switch for Low Voltage Device Activation

The MS Sedco 830 Series Combination Keyswitch and Push Plate Switch delivers reliable, secure activation of any low voltage device by integrating two switches into a single, space-saving unit. The keyswitch operates via a 1-1/8" to 1-1/4" mortised cylinder and is available with either a momentary or maintained contact configuration, while the push plate switch utilizes the 59J series face plates with a 1-1/2" x 4-1/4" all-active face plate. Mounted on a 4-1/2" x 4-1/2" stainless steel back plate, this combination switch fits a standard 2-gang electrical box or MS Sedco surface mount box, and is also compatible with radio control transmitters for added flexibility.

Why MS Sedco 830 Series?

MS Sedco 830 Series combination switches are engineered for demanding commercial access control environments, combining a UL listed SPST keyswitch and a UL listed 15-amp "Cherry" wall switch into a single, stainless steel-backed unit.

MS Sedco 830A-59J-H – Frequently Asked Questions

1) Does the MS Sedco 830-59J combination keyswitch come with a cylinder?
No cylinder is included. The 830-59J keyswitch takes a 1-1/8 inch to 1-1/4 inch mortise cylinder with a standard cam, bought separately. Order the cylinder in the keyway your building is already keyed to so the switch falls into your existing master key system.
2) What box do I need to rough in for an MS Sedco 830 combination keyswitch and push plate?
It mounts to a standard 2-gang electrical box, or to the MS Sedco #1015 surface box if you cannot cut into the wall. The surface box is sold separately. The assembly sits on a 4-1/2 x 4-1/2 inch stainless steel back plate.
3) Should I order the maintained or momentary keyswitch on the MS Sedco 830?
Momentary is the one you want if the key should trigger a single action, like one open cycle on a door operator; it is rated 125V AC, 3A and carries a black button. Maintained is for latching a state on and leaving it there, such as putting an operator in hold-open or enabling the push plate during business hours; it is rated 125V AC, 6A with a red button.
4) Can the key switch lock out the push plate after hours?
Yes. On the 830 combination unit the two switches can run completely independently, or the keyswitch can be wired to turn the push plate on and off. That second arrangement is how most facilities kill public push plate access after closing without adding a separate access control panel.
5) If I only need a key-operated switch and no push plate, what can I use instead of the MS Sedco 830-59J combination unit?
The MS Sedco 830-59J pairs a mortise-cylinder keyswitch with a 59J push plate on a single 4-1/2 inch stainless steel back plate, so you are paying for two devices in one opening. If the opening only needs key control, the Securitron MK Standard Mortise Cylinder Keyswitch is a mortise cylinder keyswitch on its own, and the Alarm Controls KA Series Ace terminal key switches are key switches without a push plate. Both are single-function key devices, while the 830-59J is the one to specify when you also want a push plate actuator at the same location and the option of using the key to enable or disable that plate after hours.
6) Will this keyswitch handle the current for a door operator or maglock circuit?
The push plate side uses a UL listed SPDT momentary Cherry switch rated 15 amp at 125V AC, so it has plenty of headroom for typical low voltage operator and release circuits. The keyswitch side is a UL listed SPST toggle, 3A momentary or 6A maintained at 125V AC. Both are dry switch contacts feeding whatever low voltage device you connect.
7) What is the relay conversion module included with the 830 combination switch for?
The RCM ships with the unit and lets a single SPST input drive two DPDT outputs at the same time. That matters when one key turn or one plate press has to fire two things at once, for example releasing an electric strike and signaling a door operator, without you adding an external relay.
8) What is the difference between the 59J-H, 59J-HSS, 59J-P, 59J-W and 59J-WSS push plates?
All five are 59J series faces on the same 4-1/2 inch stainless steel back plate, and any of them can be paired with either the maintained or momentary keyswitch. They differ in the plate face itself, so pick the one that matches the actuator legend and appearance already used on your other openings. The push plate face is 1-1/2 x 4-1/4 inches and is all-active, meaning pressure anywhere on it trips the switch.
9) Can I install an MS Sedco 830 keyswitch outdoors or in an unheated warehouse?
Its operating range runs from -40F to 185F (-40C to 85C), which covers exterior vestibules, loading docks and unconditioned warehouse space. The stainless steel back plate resists corrosion. Use the #1015 surface box where you cannot get a flush 2-gang box into a masonry or block wall.
10) What is a simpler alternative if I only need a key switch and no push plate?
If the opening does not need public push plate actuation, a straight mortise cylinder keyswitch is the cheaper, single-gang answer. The Securitron MK Standard Mortise Cylinder Keyswitch takes a mortise cylinder the same way the 830 does, without the plate. The Alarm Controls KA Series Ace terminal key switches are another option where an Ace tubular key is preferred to a mortise cylinder. Go with the 830 combination only when you want both a keyed override and a press-to-open plate in the same footprint.
11) Does the Securitron MK take the same cylinder as the MS Sedco 830 Series keyswitch?
Both are mortise cylinder devices. The MS Sedco 830 Series keyswitch operates with a 1-1/8 inch to 1-1/4 inch mortise cylinder with a standard cam, purchased separately, and the Securitron MK Series is described as a standard mortise cylinder keyswitch. If the locksmith is already keying mortise cylinders into the building master, either device works off that same cylinder family; the difference is that the 830-59J also brings a 15 amp Cherry SPDT momentary wall switch and the 59J face plate into the same 2-gang box.
12) We use Alarm Controls KA key switches elsewhere in the building. Can one of those replace the 830-59J at an automatic door?
Not as a like-for-like swap at an opening that needs both functions. The Alarm Controls KA Series are Ace terminal key switches, so they are key-actuated only. The MS Sedco 830-59J is a combination device: the keyswitch and the 1-1/2 inch by 4-1/4 inch all-active 59J push plate can run independently, or the keyswitch can be wired to turn the push plate on and off, which is how you secure a push plate actuator after hours. If the KA switch is going in where occupants also need a press-to-activate plate, you would be adding a separate push plate and box alongside it.
13) Do I need a separate indicator light to show whether the door is armed?
No, optional red and green status LEDs are available built into the 830 combination unit. They run on 12 to 24V AC or DC, so you power them off the same low voltage supply feeding your operator or access panel.
14) What finishes does the MS Sedco 830 combination keyswitch come in to match our other door hardware?
Beyond the standard stainless steel, special finishes are offered in US3, US4, US10, US10B and US32, so it can be matched to bright brass, satin brass, satin bronze, oil rubbed bronze or bright stainless trim already on the openings.
15) Can this be used with a wireless remote instead of running wire to every actuator?
Radio control versions of the 830 combination switch are available, so it can work alongside radio control transmitters for wireless activation. That is the usual approach when a receptionist or nurse station needs to release a door without a hardwired run back to the desk.
16) For an exterior or unheated location, how does the MS Sedco 830 Series compare to other mortise cylinder keyswitches?
The MS Sedco 830 Series is rated for operation from -40F to 185F on a 4-1/2 inch by 4-1/2 inch stainless steel back plate, which is the corrosion-resistant mounting you want at a loading dock, garage entry, or unconditioned vestibule. The comparable mortise cylinder device from Securitron, the MK Series, and the Alarm Controls KA Series Ace terminal key switches are both key switches in the same application family, so specify by the environmental and plate requirements of the opening rather than assuming the devices are interchangeable outdoors.
