Detex CS-2940F GRAY – Frequently Asked Questions

1) Does the Detex CS-2940F remote alarm need its own power supply, or does it run on a battery?
The CS-2940F runs on external AC power, and the AC adapter comes in the box. A 9VDC battery inside serves as backup only, keeping the alarm live if building power drops. So plan on a nearby receptacle or low-voltage feed at the mounting point rather than treating this as a battery-only device.
2) Is the Detex CS-2940F surface mounted or does it recess into the wall?
It is the flush mount version of the CS Series remote alarm, so it sets into the frame or wall surface rather than sitting proud of it. That means you need a cutout and cavity behind the mounting location. If you cannot cut into the substrate, a flush unit is the wrong choice for that opening.
3) Can I use the CS-2940F as a replacement for an existing Detex CS Series remote alarm?
Yes, it is sold as a replacement part within the Detex CS Series remote alarm family. Match two things on the unit you are pulling out: flush mount rather than surface mount, and externally powered with 9VDC battery backup rather than a battery-only or differently powered model. If the existing unit is surface mounted, the flush cutout will not line up.
4) Do I have to order a cylinder to key the CS-2940F remote alarm?
No cylinder is required on the CS-2940F. There is nothing to key and no mortise or rim cylinder to buy alongside it, which is one less line item on the order and one less keying decision for a facility standardizing keyways.
5) What does a remote alarm like the Detex CS-2940F actually do on a door?
It annunciates at a location away from the door itself, so staff at a desk, corridor, or office hear the alarm instead of relying on the sounder at the opening. Typical use is commercial door monitoring and egress security: emergency exits, stairwell doors, and stock or service doors in offices, schools, healthcare buildings, retail, warehouses, multi-tenant residential, and government facilities.
6) Will the CS-2940F keep sounding during a power outage?
Yes. The integrated 9VDC battery backup carries the alarm through an AC interruption, so coverage on a monitored exit is not lost when the building loses power. Add the 9V battery to your PM checklist the same way you would a smoke detector.
7) What color is the Detex CS-2940F, and is it a commercial-duty unit?
Gray finish, catalogued as model CS-2940F GRAY, and it is a commercial-grade product rather than a residential one. The neutral gray reads fine against painted hollow metal frames and gray wall finishes typical in schools, hospitals, warehouses, and office corridors.
