GENERAL DESCRIPTION
Relay Module, Model EM-1RI, is to be designed for use in activation of the types of products that are generally connected to an intelligent fire alarm system. It provides two sets of form C contacts that switch together (one DPDT relay). There is also an input that is capable of monitoring a dry set of contacts for open or closed conditions. The module also has on-board short circuit isolators to prevent shorts on the signaling line circuit from disabling more than one device on the intelligent loop.
