Built-in access button PNI SilverCloud PB303, NO/COM output contact, max 12V/24V 3A, stainless steel

PNI SilverCloud PB303 is a built-in access button designed for flush mounting in doors, panels or frames. The unit provides a normally open (NO) / common (COM) output contact and supports low-voltage control of electric locks and access control circuits at up to 12 V or 24 V with a maximum current of 3 A. The front plate is manufactured from stainless steel to resist daily wear and provide a neat, unobtrusive appearance in residential and commercial installations.

Advantages

The stainless-steel construction offers corrosion resistance and an easy-to-clean surface suitable for frequent use. A compact, flush-mount design reduces the risk of accidental activation and integrates seamlessly into door or panel surfaces. The NO/COM contact arrangement simplifies wiring for most electric strike and maglock setups, while the low-voltage rating makes the push button compatible with standard access control power supplies. The device is intended for reliable manual control of locking devices without requiring complex configuration.

Suitable for

• Releasing electric strikes and magnetic locks in residential entryways
• Door or gate panels where a flush-mounted push button is preferred
• Retrofits of access control systems requiring a durable, low-voltage switch
• Commercial or office doors with low-current release circuits

Key specifications

• Contact type: Normally Open (NO) / Common (COM)
• Operating voltage: up to 12 V / 24 V (low-voltage control)
• Maximum switching current: 3 A
• Mounting style: flush built-in for doors, panels or frames
• Material: stainless steel front plate
• Intended use: manual push-button control for locking mechanisms

How to use

Install the PNI SilverCloud PB303 into a prepared flush cutout in a door, frame or panel following the mounting dimensions provided by the installer. Connect the NO and COM terminals to the access control or lock release circuit, observing polarity and the voltage limits of the connected devices. After wiring, test the button operation by applying the system supply and verifying that a short press closes the circuit and activates the lock release. Ensure wiring and protective devices are sized for the 3 A maximum switching current.

Usage recommendations

Use the button with matching low-voltage access control power supplies and protective fusing to prevent overload. For outdoor or high-humidity environments, confirm that the mounting location and surrounding gasketing provide adequate protection for the flush installation. Regular visual inspection and cleaning of the stainless-steel surface will maintain functionality and appearance.
