FAQ
-
Q : Is PCAP more expensive than resistive?
Usually yes, per unit. Glass, a sensor grid, and a controller add cost. Many teams accept this for clearer images and better durability.
-
Q : Does water affect a PCAP screen?
It can. Water droplets may cause false touches. Controllers with water handling reduce the problem. Heavy water flow is still harder.
-
Q : Can a PCAP screen work with gloves?
Often yes. A controller with glove mode can read a gloved finger. Results depend on the glove, so test with the real glove.
-
Q : Is PCAP the same as PCT?
Yes. PCT stands for Projected Capacitive Technology. The terms are used for the same thing.
-
Q : What does PCAP stand for?
Projected Capacitive. It is a touch technology that reads finger position through an electric field.
-
Q : Can a PCAP screen work next to a power supply?
Yes, in most designs. But test it early. Layout and grounding affect results as much as the module does.
-
Q : Is PCAP always better than resistive?
No. PCAP wins on clarity and gestures. Resistive technology is ideal for surfaces that are often wet or covered by thick gloves. Choose the option that best matches your environment.

Q : How long should a fire alarm panel display last in the field?
Fire alarm systems are frequently specified with service lives of 10 years or more. Display technology selection should account for this — favoring proven, long-supply-cycle components over the newest available part.
