Need help?Do you have a question about the BAS-IP SH-42 and is the answer not in the manual?
The BAS-IP SH-42 is a two-locks control module designed to enhance the security and control capabilities of an intercom system. It facilitates the connection and control of two independent locks, either electromechanical or electromagnetic, from an outdoor panel, an internal monitor, or a SIP client. The module communicates with the call panel via an RS-485 interface, allowing for remote lock management, which is particularly useful in systems requiring enhanced security where locks need to be located away from the call panel itself.
The SH-42 module features two built-in relays, each capable of controlling a separate lock. This allows for flexible configurations, such as connecting two electromechanical locks, two electromagnetic locks, or one of each type. The relays are independent, meaning they can be controlled separately. The module supports both electromechanical locks, which typically use normally open (N.O.) contacts, and electromagnetic locks, which usually require normally closed (N.C.) contacts. Each relay has a switchable contact group (COM, N.O., N.C.) to accommodate different lock types.
For enhanced control, the 8-pin version of the module includes additional inputs. It can connect two external exit buttons, one for each relay, allowing occupants to open the first and second locks respectively. Furthermore, it features a dedicated input for a fire alarm system. When a fire alarm signal is received, the module can be configured to trigger specific actions, such as unlocking doors for emergency egress.
The module's communication with the call panel is primarily through the RS-485 interface. In a typical setup, four wires are used for this connection: +12V DC power supply, Ground, 485+, and 485-. This configuration enables independent control of both relays. Alternatively, for simpler setups or when connecting to an external low-voltage signal source, the module can be connected with three wires: +12V DC, Ground, and a "Lock" control input. In this three-wire configuration, only the first relay can be controlled, and the "Lock" input requires a low-voltage analog signal with a DC voltage between +9V and +12V.
The SH-42 also incorporates a controller for adjusting the opening delay time of the locks. This feature is crucial for optimizing the operation of different lock types. The delay time determines how long the relays remain in their switched state after an opening signal is received from the RS-485 interface, the "Lock" input, or an exit button.
The SH-42 offers versatile connection options for various intercom system configurations. For full functionality and independent control of both locks, the RS-485 interface with four wires (+12V DC, Ground, 485+, 485-) is recommended. This allows for comprehensive management from the call panel.
When connecting to a multi-unit call panel or an external low-voltage signal source, the "Lock" input can be utilized. This input is designed for a low-voltage analog signal (DC +9V to +12V) and will only control the first relay. This setup is suitable for scenarios where only one lock needs to be controlled or when integrating with existing external control systems.
The module's ability to connect both electromechanical and electromagnetic locks provides significant flexibility. For electromechanical locks, the COM and N.O. contacts are typically used, and the opening delay time should be adjusted to a short duration, ideally between 0.5 to 1 second. For electromagnetic locks, the COM and N.C. contacts are generally used, and a longer delay time, typically between 4 to 8 seconds, is recommended. It is critical to adhere to these recommended delay times, especially for electromechanical locks. Setting a delay time longer than 2 seconds for electromechanical locks can lead to a high probability of failure due to the design features of their magnetic coils.
The 8-pin module's additional inputs for exit buttons and fire alarm enhance its utility in various access control scenarios. The exit buttons provide a convenient way for users to open doors from the inside, while the fire alarm input ensures that doors can be automatically unlocked during emergencies, improving safety.
The SH-42 module is designed for reliability and ease of integration. While specific maintenance procedures are not detailed in the provided information, general best practices for electronic devices apply. This includes ensuring proper power supply, secure connections, and operating within the specified environmental conditions (temperature and humidity).
The product comes with a warranty period of 36 months from the date of sale. For warranty repairs, the product must be in its original packaging, accompanied by a properly filled warranty card, and have intact stickers or labels. The warranty card should include the model name, serial number, purchase date, seller's name, company stamp, and customer's signature. Transportation for warranty repair is the responsibility of the buyer. The service center aims to complete repairs within 24 working days, and any time spent on repair is added to the warranty period. This warranty is in addition to, and does not restrict, constitutional and other consumer rights.
