Code Blue 40064 Replacement Speaker Kit (3-Pack)
Overview
The Code Blue 40064 is a 3-pack of 4 ohm replacement speakers built for field service and new-build installs on Code Blue emergency callstations. Model 40064 solves the common depot problem of a single failed speaker forcing a truck roll to a campus or parking structure call tower — stock a kit and swap the driver on site instead of waiting on a special order. Each speaker in the kit shares the same 4 ohm impedance, so any unit from the 3-pack drops into a compatible callstation without an impedance mismatch that would otherwise strain the onboard amplifier.
Compatibility
Rated for the IA4100 series Code Blue callstation. Confirm the impedance rating on the existing speaker (4 ohm) before ordering, since mismatched impedance across a callstation's audio path can distort output or overdrive the amp. If you manage a mixed fleet of Code Blue towers, keep the 40064 kit on hand specifically for IA4100 deployments rather than assuming cross-compatibility with other series.
Installation Notes
Because these are outdoor emergency towers, reseal any gasket or conduit opening disturbed during the speaker swap to maintain the enclosure's weather protection — a compromised seal at the speaker cutout is a common cause of moisture ingress on pole-mounted and wall-mounted call towers. Budget one spare per active site if the tower sees heavy weather exposure, since replacing all three at once from a single kit is more efficient than repeat service trips for one driver at a time.
