Collins Aerospace's Kidde Dual Spectrum® control electronics panel (CEP) combines fire suppression system control and interface functions into a single unit. This approach reduces component weight and simplifies and reduces the weight of electrical wiring harnesses. This CEP is capable of multiple zone detection and can drive up to eight high-speed extinguishers. It controls system power, manages system operation and can communicate with other vehicle subsystems.

The CEP monitors sensors automatically at startup and built-in test (BIT) may be manually activated by the operator at any time. When a fire is detected by a sensor, it will activate the appropriate extinguisher within milliseconds. If a crew extinguisher fails to operate, it can automatically activate a backup extinguisher. It provides the appropriate warnings and faults to inform the operator here the fire occurs, and which extinguishers were activated to suppress the fire.

The CEP includes power status indicators, engine fire warning activation, manual release, LAMP/BIT test initiate switch, and fault indicators. It is designed to interface with the PM-34CBEH and PM-34CSBEH (supervised) Dual Spectrum Infrared discriminating sensor with full BIT.
