Connections for Low-Current Auxiliary Relays
Cable assemblies 1751542-NY (SSP2000B) and 1751542-01 (SSP3000B) includes
18-inch, 18 AWG leads for four solid-state relays. The relays are 12 Vdc out only
(active high) with these software-configurable options:
• Steady-on lighting or one of five flash rates for small flashing lights.
• Synchronized or alternating flashing for two or more small flashing lights.
Figure 8 on page 24 shows the connectors for the relay cable assembly on
the back of the siren amplifier/relay module. The relays are protected inside the
module by electronic short-circuit detection circuits.
Extend wiring with 18 AWG leads or thicker. Insulate spliced leads with twist-on wire
connectors. Fold and seal unused leads.
