The radio expanders for the i-onEX range of control units provide channels for either 10 radio detectors (EXP-R10) or 30 radio detectors (EXP-R30). In addition each radio expander provides channels for:
Two i-rk01 radio keypads.
Two 760ES external radio sounders.
Two Wireless Accessory Modules (WAMs).
Each radio expander also provides wired connections for a Loudspeaker.
Note: The total number of radio detectors that can be
handled by an i-onEX control unit depends partly on the density of radio
transmitters within a given volume. If there are more than 30 transmitters
