The personal alarm is a cute little accessory based on personal defense alarms that can sometimes be found in Japan and other countries and are carried by children, young ladies or anyone who feel the need for some way to atract attention in case of emergency.
A brief left-click on the alarm will cause your avatar to yank the pin out of the device and throw either the pin (pullpin version), or the device itself (grenade version)
From that point the device will flash and the alarm sound will begin to play, and will do so until the temporary projectile is “re-attached” or eventually derezzes (through parcel auto-return, manual delete, or timeout).
The projectile is always thrown in the direction the person using it is facing.
If the user is close enough, the projectile can be clicked to attempt to re-attach it. This can be performed by the object's owner or anyone else in range, but the object owner will have to be close enough too.
When thrown, the device will leave a trail particle to make it easier to track where it went.
In addition, once it stopped moving, the device will display yellow arrows to indicate its position.
To use the primary function, the land that the owner is standing on has to be configured to allow them to rez objects and run scripts. If this isn't the case, a message indicating that the device won't budge will be displayed.
Clicking and holding down the left mouse button allows the owner of the object to toggle the “signal beacon” mode of the KDC personal Alarm on or off. It will simply light up the device's LEDs (no flashing) to make it more visible at night.
The pullpin variations of the KDC Personal alarm have a little strap and a red handle attached to the pin. When the device is thrown, the pin, handle and strap assembly will be thrown and the alarm will remain on the wearer/owner.
The grenade variation does the opposite and when thrown, the alarm itself will be thrown while the pin will remain on the wearer. It is purely a matter of preference.
The red handle was added to make the thrown object more visible, but can be safely edited out if you wish to customize your Personal Alarm.
In the default configuration, the KDC Personal alarm is configured to be fully public, which allows anyone in a 2 meter range to yank and throw your personal alarm.
If this behavior is not something you wish, there are two notecards inside the Personal Alarm inventory that can be renamed to change this behavior:
The KDC Personal Alarm is designed to be modification friendly and safely supports the following:
The linking order doesn't matter as long as the alarm unit is the root prim and all the other objects are named accordingly.
The shipped alarms are set to attach to the chest slot by default and are not placed in any specific fashion since I cannot predict where you will want it attached (belt? backpack? somewhere else?).
So unfortunately you will have to place it yourself. The different parts should give you plenty of options to make it hang just right
