The DTK-TSS3 includes a 2-position hardwired base to add surge protection for signaling and notification circuits.

• Hard-wired base for 2MHLP/2MHLPB modules to protect up to 4 SLC, NAC, IDC and PIV circuit pairs (2MHLP modules sold separately)
• Perfect solution for building-to-building notifier and communication runs
• Installed in a NEMA 4X enclosure

The DTK-2LVLPF protects 24V SLC loops on first generation fire alarm control panels, where surge protection and current limiting functionality are required.

• Protects up to 2 pairs of SLC loop circuits
• Low-current fusing prevents induced surges from damaging sensitive equipment
• Series connection, parallel function adds no resistance to loop circuits
