Components 

1)

 

The C406-1 Series ELT main assembly is housed in a high impact, fire resistant, polycarbonate plastic case, 
which is enclosed in a protective mounting frame assembly made of similar material. See Figure 2. 

NOTE: 

The ELT main assembly and its mounting frame assembly are capable of withstanding 

extremely harsh environments and have been subjected to the rigorous environmental 
testing required by COSPAS-SARSAT for certification. 

 

Figure 2 C406-1 Series ELT and Mounting Frame Assembly 

2)

 

The cockpit-mounted remote switch assembly is comprised of an ELT status LED and control switch, which 
allows an operator to monitor ELT status and manually turn on the ELT (i.e., activate) for testing and reset 
(i.e., deactivate) the ELT. See Figure 3. 

NOTE:  The ELT CANNOT be disarmed or disabled from the cockpit. Cockpit operation is limited to 

deactivating or manually activating the ELT.
