MMTC PRH-100-ADA Interior Flush-Mount Emergency Egress Control
The MMTC PRH-100-ADA is an interior flush-mount emergency egress control with a handle that extends slightly from the faceplate for ADA-style access requirements. It is used where a manual release station is needed at an access-controlled door, pedestrian gate, secured area, or similar opening.
Like the standard PRH-100, this unit includes 15 feet of cable with an S-hook for connection to compatible mechanical release hardware. The key difference is the handle style. The ADA version is selected when the pull handle needs to be more accessible than the flush-handle PRH-100 version.
This product should be treated as part of an egress system. The faceplate, back box, release linkage, cable path, and final hardware must all work together so the opening can be released when needed. It is not a universal electric switch and should not be substituted for code-required egress hardware without review.

Technician Note
Select PRH-100ADA when the handle projection is required. If the existing device is flush to the faceplate, compare against PRH-100 before ordering.
Before Ordering Checklist
- Confirm ADA-style handle projection is required.
- Verify the release hardware can be operated by the included cable and S-hook.
- Check faceplate and back box dimensions against the existing opening.
- Confirm cable routing will not bind or reduce release travel.
- Test the complete release after installation.
Professional Advisory
Emergency egress control installation should be reviewed against the specific opening, local code, and accessibility requirements. Do not install egress hardware in a way that traps occupants or prevents emergency release.
Important Ordering Warnings
- PRH-100ADA is not the same as PRH-100; the handle style is different.
- This is a mechanical egress control, not a monitored safety sensor or powered access-control relay.
Product Questions & Answers
Why choose PRH-100ADA instead of PRH-100?
Choose PRH-100ADA when the project requires the handle to extend slightly from the faceplate for ADA-style access.
What cable length is included?
The unit is commonly listed with 15 feet of cable and an S-hook.
Is this used outdoors?
It is an interior flush-mount emergency egress control. Exterior or wet locations require hardware rated for that environment.
Does it unlock the gate or door by itself?
It operates a compatible mechanical release linkage. The lock, latch, or gate hardware must be designed to work with that release.
Should this be tested after installation?
Yes. Any emergency egress release should be tested after installation to confirm it releases the opening reliably.
