Securitron SN-1 Spike and Noise Suppresor

Keep critical security and surveillance equipment online with the Securitron by ASSA ABLOY SN-1 Spike and Noise Suppressor. Specifically engineered for low-voltage control inputs, the SN-1 reduces service interruptions by suppressing harmful voltage spikes (up to 1500 watts) and filtering high-frequency RFI noise that can cause erratic behavior in access control, alarm panels, and CCTV systems. Its bi-directional design supports both 12V and 24V AC or DC, so installers can hook it up quickly without worrying about polarity.

The SN-1's small 0.4" depth makes it ideal for use inside door controllers, power supply racks, and compact security enclosures where space is at a premium. Built RoHS-compliant, it provides a durable, code-friendly solution for commercial and institutional deployments. Note: optimized for low-voltage control and power lines—it's not intended for high-frequency data transmission lines.

Add the SN-1 to your next access control, monitoring, or surveillance project to protect electronics, reduce false alarms, and extend equipment life. Order now to harden your security systems against spikes and interference.

• Protects sensitive security and surveillance electronics from damaging voltage spikes and RFI, reducing downtime and service calls
• Bi-directional design works on 12 or 24V AC or DC, eliminating polarity errors and simplifying installation for access control and monitoring systems
• Suppresses up to a 1500-watt surge to guard control inputs, locks, and power supplies against transient events
• Compact, low-profile package (0.4" depth) fits into tight enclosures and field panels without added bulk
• RoHS lead-free construction for environmentally compliant installations in commercial and government security projects
