GE NX-10 Installer Manual page 34

To allow the IO module to control the output on the outdoor siren, you need to cut jumper 3 and then
optionally 1 and/or 2.
Jumper 3 is a start-up protection. Jumpers 1 and 2 are responsible for timer settings, and you can cut
one of them or both, according to the table below. The maximum siren activity time is limited both
by hardware (jumper) setting, and software (RF Receiver 32>Outputs>Siren/IO>Time) time setting,
whichever is shorter. For example, even if the software setting for a siren is set at 255 minutes, and
the jumper J1 is cut, the siren will sound for 5 minutes only (i.e. according to the hardware limit).
When the same jumper is cut, and the time value for the Siren/IO module is set to 1 minute, the siren
will stop after 1 minute.
