Frequently Asked Questions
Q: Does this wireless exit button work with any access control system?
A: The Asia-Teco CNB501H uses a standard NO/COM relay output, making it compatible with most electric strikes, magnetic locks, and automatic door controllers that accept a dry-contact signal. Always verify your controller's input specifications before installation.
Q: How far away does my hand need to be to trigger the infrared sensor?
A: The infrared proximity sensor is designed to detect a hand gesture at a typical range of a few centimeters up to the rated detection zone, triggering the wireless signal to the 2.4GHz receiver. The receiver can be located up to 25 meters away from the transmitter.
Q: Are batteries included with the exit button?
A: No. The transmitter requires 2 × 3V (CR-type) batteries, which are not included. The wireless receiver is powered by your existing AC/DC 12–36V door system supply.
Q: Can this device be used outdoors?
A: The CNB501H is rated for operating temperatures from -42°C to +45°C and humidity from 10–90% RH, giving it broad environmental suitability. However, it is not rated as fully weatherproof (IP-rated), so if mounting outdoors it should be protected from direct rain and moisture ingress.
Q: How long will the transmitter batteries last?
A: The transmitter is rated for more than 20,000 activations per battery set, providing very long service life under typical usage conditions.
