Protectowire RB-4

Description

Auxiliary signaling relays are often needed to provide an interface to other systems for annunciation and/or electrical shutdown. The RB-4 Relay Module provides 4 individually zone activated sets of Form “C” contacts in one module.

The RB-4 relays are normally de-energized. Each relay ( 1 – 4) is activated by an alarm of its corresponding input circuit (1 – 4). Indicators L1 through L4 (Red) illuminate when the corresponding relay is activated.
