Arrow S646 – Frequently Asked Questions

1) Which Arrow exit devices does the S646 top strike fit?
The Arrow S646 top strike is made for Arrow S1150 and 3700 Series exit devices. It is built for those two families specifically, so it drops into the existing prep without modification. If your device is another Arrow series or another brand, this is not the strike for it.
2) Is the Arrow S646 top strike fire rated for a labeled door assembly?
Yes, the S646 is a UL fire rated top strike. On a labeled opening the strike is part of the rated assembly, so using the genuine fire rated component keeps the exit device installation code compliant rather than voiding the label with a generic substitute.
3) What does a top strike do on a vertical rod exit device, and why would I be replacing one?
The top strike is the piece mounted at the head of the frame that the top latch of a vertical rod exit device engages. It takes the impact every time the door closes and latches, so on high traffic openings it wears, bends, or gets torn loose before the device itself does. Replacing just the strike restores latching at the head without pulling the whole device. The S646 is the top strike for Arrow S1150 and 3700 Series devices.
4) Can I use an aftermarket strike instead of the genuine Arrow S646?
On a fire rated exit device, no. The S646 is a genuine Arrow UL fire rated replacement part, and substituting a non-listed strike on a labeled opening puts the assembly's fire rating in question. It also changes the latch engagement geometry the Arrow top latch was built around. Stay with the S646 on S1150 and 3700 Series devices.
5) I manage a building with Arrow 3700 exit devices on several doors. Can I stock one part number for all the top strikes?
If those doors are Arrow S1150 or 3700 Series vertical rod devices, the S646 is the single top strike part number to keep on the shelf for all of them. One line item covers both series, which is what you want for a fleet of openings being serviced by different techs.
6) Is the S646 top strike rated for commercial traffic or is it a residential part?
Strictly commercial. Arrow classifies the S646 as a commercial product, built for high traffic door hardware service in offices, schools, hospitals, retail, warehouses, government buildings and multi-tenant residential properties.
