A The 2 holes in the device are for attaching using wire, string or screws. The notches around the middle of the device is for when using with a cable-tie.
Firmly attach the device in an upright position using screws, wire, string, tape or a cable-tie. Pull up the firing pin (1) until you can see the hole for the safety device (supplied). Insert the safety pin through the hole (2).
I prefer to use a special pin that can be 'locked off' and cannot get accidently removed. With the safety pin in place it is impossible for the Ice Bear Alarm to fire, so if it is tripped in error, it won't discharge.
B Pull the firing pin up a little more (3). When the groove in the shaft appears, insert the release sear into it (4).
By experimenting with how far the release sear is inserted, you can choose how much force is required before the alarm detonates. You can do this without wasting 12g blanks.
Make sure you attach the tripwire to the release sear with a non-slipping knot.
Stretch the tripwire from the alarm to another firm object - usually another corner post - and tie off (5). Slide the blank cartridge fully into position (6).
If it is very windy use the clip provided to prevent any chance of the cartridge jiggling out of firing position.
Finally, gently remove the safety device (7).
The device is now armed and ready to fire.
The alarm may also be used upside down if pyrotecnic cartridges are being used, for example screechers, or aerial bangers (see video clip).
