Module Bay Description

Remote Annunciators

Remote annunciators include a bay assembly, a power distribution

interface module (PDI), a Transponder Interface Module, and an

interconnect harness. Communications with the host fire alarm

control panel are through a Remote Unit Interface (RUI or RUI+)

connection that allows for up to 2500 ft (762 m) distance. RUI can

communicate with up to a total of 31 remote devices for each master

controller (on one or multiple RUI channels) and can be wired as a

Class B or Class X communication pathway. Wiring can be either

shielded or unshielded, twisted, or untwisted single pair wiring.

Optional Expansion Bays

Each includes a PDI and accept a variety of optional modules for

specific annunciator functions.

The Battery Compartment

The battery compartment (bottom) accepts two batteries, up to 50 Ah.

Battery mounting does not interfere with available module space.

Remote Command Center

The optional Remote Command Center occupies the top bay of a Remote

Annunciator. It provides an LCD status readout with keyswitch activated

control switches and a local tone-alert sounder. Features are essentially

identical to the Remote LCD Annunciator model 4603-9101 (reference

document S4603-0001).
