Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: Does this wireless exit button work with any access control system?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How far away does my hand need to be to trigger the infrared sensor?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are batteries included with the exit button?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this device be used outdoors?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long will the transmitter batteries last?\u003c\/h4\u003e\n\u003cp\u003eA: The transmitter is rated for more than 20,000 activations per battery set, providing very long service life under typical usage conditions.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Does this wireless exit button work with any access control system?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.
