SH-M30 digital building visual intercom system is one of the series products developed and produced by our company. The product adopts advanced microcontroller chip and large-scale integrated circuit, which can realize the functions of visual intercom between visitors and residents and communication between residents, and has the characteristics of simple wiring, high reliability, strong confidentiality and good expansibility.

SH-M30 digital building visual intercom system consists of visual door machine, visual indoor machine and system power supply.

2. Digital portal crane (model: SH-M30A)

L function

You can use the extension to realize visual intercom.

Remote unlocking of receiving extension.

With night vision function.

L usage method

Visitors can dial the indoor extension directly by pressing the number keys (for example, to dial Room 2 on the third floor, just press the number keys "3", "0" and "2" continuously), wait for the incoming call, and then press the # key.

Turn off the phone automatically after 30 seconds of talking. If extension is needed, press any key of 1-9.

If you press the wrong room number, press the * key to cancel, and then re-enter the room number.

Method for setting room number called by door machine

In order to meet different needs, the portal crane can be set with 3 or 4 room numbers. On the circuit board of the portal crane, there are two jumpers ④ and ⑤. By connecting and disconnecting jumpers ④ and ⑤, different room number combinations can be set:

Example 1: A building has 9 floors, with 4 households on each floor. Select mode 1 and connect jumpers ④ and ⑤.

Example 2: A building has *** 14 floors, with 2 households on each floor. Select Mode 2, with jumper ④ turned off and jumper ⑤ turned on.

Example 3: A building with 25 floors and 8 households on each floor, then choose Mode 4, with jumper ④ disconnected and jumper ⑤ disconnected.

Example 4: There are two buildings, each with 8 floors and 2 households on each floor. However, in order to realize the call between residents across buildings, "1" must be added before the room number when calling the indoor unit in the first building, and "1802" must be entered if calling 802 households; When calling the indoor unit in the second building, you must add "2" before the room number. If you want to call 802 households, you must enter "2802". The purpose of this is to distinguish the same room number between two buildings, so as to realize the call between the residents across the building. To sum up, mode 4 is selected for both portal cranes, with jumper ④ disconnected and jumper ⑤ disconnected.

Note: When different modes are selected, the room number coding method of indoor unit is different.

Iia。 Visual indoor extension (model: SH-D39 series)

L function

Called by the machine at the door

Talk to the machine at the door

open the door

The monitoring button can monitor the door at any time.

Call other residents in the system.

L usage method

When there is a door-to-door call, the indoor branch will ring a bell or music, and the image of the door-to-door visitor will be displayed on the screen. At this point, you can talk by lifting the microphone of the indoor unit.

During the call, if you want to open the door lock, you can press the "Unlock" button, the door lock will be opened immediately, and the hanging-up image will be automatically extinguished.

If you want to call other residents, please go off-hook first, and then press the # key. When you hear the dial tone, press another room number. When the other party goes off-hook, you can make an internal call (this function is only effective when the door phone is idle). If you can still hear the dial tone during the call, the receiver only needs to press any key from 0 to 9 to cancel it.

If you want to monitor the situation at the door, you can press the "Monitor" button and the screen will display the image of the door. After about 30 seconds, the screen will automatically close.
