The DTK-MRJ31XSCPWP is a modular surge protection device designed to protect fire and security system dialer circuits. This point of use surge protector can be easily installed in series with the circuit.

• Single pair RJ31X dialer circuit protection with patch cord
• RJ45 modular jack with external grounding screw
• Sneak Current Protection - SCP: 150mA self-resetting fuse protects against repeated surges

The DTK-TSS1 includes a DTK-120SRD for AC power surge protection with remote monitoring, and a 5-position hardwired base to add loop circuit protection. Installed in a NEMA 1 steel enclosure.

• Protects 120VAC power with dry contacts for remote monitoring of surge protection status
• Hard-wired base for 2MHLP/2MHLPB modules to protect up to 10 SLC, NAC, IDC and PIV circuit pairs (2MHLP modules sold separately)
• Space for expansion, protect up to 8 additional data/signal pairs by adding a DTK-4MB Base
