LEE DAN 1877-010 Surge Protector for Telephone Line

Protect critical phone-based communications and surveillance links with the LEE DAN 1877-010 Surge Protector for Telephone Line. This surge protection module is engineered to safeguard telephone equipment and line-connected monitoring devices—such as alarm dialers and legacy surveillance modems—by clamping transient surges and isolating harmful spikes before they reach your gear. The protector provides full-line coverage with tip-to-ground, ring-to-ground and tip-to-ring protection and features an approximate 200V clamping voltage for reliable suppression of typical line transients.

Designed specifically for use on standard Central Office (C.O.) tip and ring lines, the LEE DAN 1877-010 integrates cleanly into professional AV, security and networking installations. Its sacrificial design means the suppressor may be sacrificed in an extreme event to preserve more expensive downstream equipment, minimizing downtime and replacement costs. Manufacturer part number 1877-010 is Guardsman protection-plan eligible for added peace of mind. Ideal for security, surveillance and remote monitoring applications that rely on telephone lines—add this surge protector to your install kit or contact sales for bulk ordering and technical support.
