Established in 1990, China JouYang Electrical Products Co.,Ltd. is known as a leading safety relay manufacturer and designer of high and low-voltage electric appliance in China. We integrate scientific research, development, production, sale and service in one company. Our custom safety relays products are characterized by their superior dustproof, splash-proof, anticorrosion, fire-resistant, thermo-stability and aging-resistant properties. Having received ISO9001 certification for our manufacturing and sales systems, we have also been issued European 'CE' and Chinese 'CCC' safety authorizations for our products. All of our OEM safety relay products are strictly according to IEC/GS/EMC/LICE/UL/CSA standard and guaranteed by People's insurance Corporation of China (PICC).

Intelligent self-diagnostics
Heat sensor is available with all T model detectors
Auxiliary Relay used to activate other devices such as elevator recall, door holders, strobes, etc. Listed for releasing service.
Advanced false alarm immunity
Meets NFPA 72 field sensitivity testing requirements without the need for external meters
The 449 series self-diagnostic, 4-wire smoke detectors continually monitor their own sensitivity and operational status, and provide a visual trouble indication if they drift out of sensitivity range or fail internal diagnostics.The 449 series is easily cleaned by replacing the proprietary fieldreplaceable optical chamber. All models are designed to reduce false alarms from dust, insects, RFI and external light. An integral combination rate-of-rise and fixed 135-degree F, 50-foot rated.

Stainless steel digital - connects to your security system to trigger entry & programmed commands
Two heavy-duty relays can be programmed to be normally open or normally closed
Program up to 111 different user codes to allow entry to employees, workers, or guests
Dimensions: 4 5/8" x 2 7/8" x 1 7/8"
Code Combinations: 100 million possible
If you have a hardwired security system set up in your home, you can easily allow entry to a door or gate through a digital keypad. The Digital Keypad With 2-Relay Output will connect to most alarm control panels, and it has two built-in heavy-duty relays, which are programmable for normally open or normally closed. Connect a door strike or gate opener for easy remote access. Up to 111 different user codes can be programmed into the Digital Keypad With 2-Relay Output, including a duress code, which will allow the user to activate the keypad while simultaneously sending a panic signal or activating a telephone dialer to call for help. With over 100 million possible codes and multiple levels of codes, you're ensured of a completely secure product that even features protection against unauthorized use: The keypad can lock out or send a duress call after multiple unsuccessful attempts to key in the code.
