The optional APPM is a modified battery pack that shuts down the output of the X26P ECD after 5 seconds and also contains a built-in speaker that alerts you to the impending shut down.
Under stressful situations, audio exclusion might prevent you from hearing the alert from the APPM.
The APPM provides an audible beeping alert for the last 2 seconds of a trigger-initiated cycle before automatically shutting down the cycle. After 5 seconds’ deployment duration, the energy burst will stop even if your finger is still pulling the trigger switch. To reenergize the deployed cartridge, first ensure that your finger is off the trigger switch, and then press the trigger again.
Your ECD will recognize the APPM as a unique type of battery pack. If you remove the APPM and replace it with a different type of battery pack, the X26P ECD will return to its normal configuration. That is, there will no longer be an audio alert, and the energy cycle will continue after 5 seconds if your finger is still holding down the trigger switch. Always confirm that the ECD performs as expected before returning it to duty after changing any battery pack.
Remove the cartridge before testing the ECD function. See the Unloading section in this manual for more information.
