Classroom function (08) means free egress from the inside at all times through the push bar, while the outside 4908A trim controls entry. With the electric latch retraction and the door position switch built in, the outside lever can be released by an access control system, and the door position switch reports whether the door is actually closed back to the panel. That combination is what schools, healthcare and multi-family corridors use when they want card access in and code-compliant egress out.

A strike is a required selection, and there are two: ALS for an aluminum door and frame, HMS for a hollow metal door and frame. Rim devices latch into a surface strike on the frame stop, so the strike has to match what the frame actually is. Aluminum storefront gets ALS; a steel frame in a masonry or stud opening gets HMS. Get this wrong and the latch will not seat properly.

The 4908A trim is included with the device, so you are not sourcing outside trim on a separate line. You do still have to choose a strike, ALS for aluminum or HMS for hollow metal, and you will need to run power to the opening for the electric latch retraction and wiring back to your panel for the door position switch.

The nearest peer is the SDC S6136 Spectra, a 36 inch electrified architectural rim exit device with a 4 inch wide stile chassis and a door thickness range of 1-3/4 inch to 2 inch. Both are 36 inch electrified rim devices. The Dormakaba TS unit is built around an electric latch and door position switch with 4908A classroom trim and hex key dogging, so if the access control scheme needs the door position signal reported from the device itself, confirm the S6136 configuration provides that before swapping.

For a 48 inch leaf, the peers at that length include the Cal-Royal 5500 48 inch Grade 2 heavy duty push bar device, the Cal-Royal A9820 48 inch heavy duty device, the Corbin Russwin ED3200 Grade 1 48 inch crossbar device for 1-3/4 inch doors, the CRL Jackson 1095 Series 48 inch crossbar device, the Marks USA M9900F 48 inch fire rated device, and the Sargent 2828 and 3828 Grade 1 reversible devices for 48 inch minimum door width. The Dormakaba TS unit is a 3 foot device.

Yes. The TS Series device uses hex key dogging, so with a hex wrench you can depress and hold the push bar down to keep the latch retracted for free push-pull traffic during open hours, then undog it at close. Note that hex dogging is a feature of non fire rated devices; on a fire door, mechanical dogging is not permitted.

A rim device latches into a single strike on the frame stop, which makes it the simplest exit device to install and maintain on a single door in a frame with a stop. It is the right choice for a standard single leaf opening. If you have a pair of doors with no center mullion, a rim device will not work on both leaves and you want a vertical rod device instead, such as the Hager 4501 concealed vertical rod for a wide stile leaf or the Hager 4601 for a narrow stile leaf.

For a 36 inch electrified rim device on a wide stile leaf, the SDC S6136 Spectra S6000 Series is the closest alternative we carry, rated for 1-3/4 to 2 inch door thickness. If you only need the bar to release a separately mounted electromagnetic lock rather than retract a latch, the SDC MSB550 mechanical switch bar or the SDC SureExit PSB560 pressure sense bar handle that, and both suit narrow or wide stile. The Securitron EMB electromechanical exit bar is another electrified option, listed for 2-1/4 inch doors.

630 satin stainless steel, and that is the only finish offered on it. 630 is the standard commercial finish that matches most stainless pulls, closers arms and hinges already on institutional openings, so it drops into an existing building standard without looking off.

It is a commercial rated device, built for the traffic you get in schools, offices, healthcare and multi-family common areas rather than residential use. The classroom function plus electric latch retraction and door position switch is a standard specification for openings that need credential entry and monitored door status.
