1. Single-number model: After powering on, the first audio segment (ringtone) plays in a loop. The sixth audio segment plays each time the phone is picked up (plays once). The second audio segment plays each time the correct number is entered (plays once each time the number is entered correctly). This triggers the mechanism to unlock and illuminate (or triggers the push rod).
Single-number models are available in A, B, and C:
Model A - A correct number entry triggers unlocking and a voice message plays simultaneously. Relay 1 energizes for 10 seconds after each correct number entry, then automatically recovers. Relay 2 energizes for 1 minute, then automatically recovers. The mechanism automatically resets after 1 minute.
Model B - Unlocking is triggered only after the correct number entry completes the voice message. Relay 1 energizes for 10 seconds, then power-on again for relay 2, and the mechanism resets.
Model C - A correct number entry triggers unlocking and a voice message plays simultaneously. Relay 1 and relay 2 power-on again for relay 2, and the mechanism resets. 8-number model: Powerful, supports up to 8 phone numbers. All 8 numbers can be dialed in any order. Each correct dialed number plays a corresponding tone. Repeatable dialing is supported. Dialing number 1 triggers a tone that activates relay 1, while dialing number 2 triggers a tone that activates relay 2. The remaining 6 numbers only trigger the corresponding tone. After triggering the mechanism, power is cycled to reset. Each phone number can be up to 20 digits.
Motion sensor call trigger version: Supports two numbers. The first number triggers the mechanism with a password, and the second number triggers a tone with a password. Three minutes after power-on, the mechanism activates. Upon detecting a person, the phone rings (tone 1). Picking up the phone plays a tone (tone 2). After hanging up, pick up the phone and enter the first number to play tone 8 (which unlocks the door, illuminates the light, or triggers the actuator motor). Entering the second number plays tone 9. The second number can be entered repeatedly. It automatically resets after 3 minutes.
4. Triggering the phone with metal, buttons, or magnetic objects: After powering on, first allow the magnetic sensor to contact the incoming call to ring. Answer the call, play a tone, and trigger Relay 1. Then hang up and dial the designated number to trigger another tone and unlock Relay 2. An incoming call must precede dialing. Incoming calls and dialing can be triggered repeatedly, and the relay must be powered on to reset.
5. Two-number combination: Pick up the handset and dial number 1 to play tone 1. After hanging up, dial number 2 to play tone 2. After tone 2 finishes, Relays 1 and 2 unlock. If the wrong number is dialed, tone 3 will play. Number 1 must be dialed before dialing number 2. The tone can be triggered repeatedly, and the relay must be powered on to reset. VI. 4-way incoming call - 2-group dialing: Press button 1 - the phone rings - answer and play voice 1. Press button 2 - the phone rings - answer and play voice 2. Press button 3 - the phone rings - answer and play voice 3. Press button 4 - the phone rings - answer and play voice 4. Dial number 1 and play voice 5, and unlock 1 (relay 1 energizes). Dial number 2 and play voice 6, and unlock 2 (relay 2). Incoming calls and dialing are not prioritized. Each button press triggers the ringing again, and each number dialed plays the voice again. After the lock is unlocked, it must be powered on again to reset.
