SURE SG800T - UV Alarm Specification

SureGuard Unique 3 in 1 Gas Alarm - Sound, Smell and UV

The unique Trident Attack Deterrent with three simultaneous functions is specially designed so that upon activation it produces an ear-piercing 138 decibel sound output and also releases a repelling odour and an ultraviolet tracer.

Upon activation, an ear-piercing 138 decibel sound is emitted which acts as both a means of disorientating the assailant and as a shout for help. Also, an unpleasant odour and particles of ultraviolet tracer are discharged from the actuator in a radius of 40cms in front of the Alarm.

The repellent odour acts to discourage the attacker, and leaves a distinguishable smell on the attacker's skin and clothing which are also marked by the ultraviolet tracer, leaving no obvious mark except when it is exposed to an ultraviolet light source such as those used by the Police.

The Trident Personal Attack Deterrent has been designed to operate at any angle, even upside down. The lock-down facility on the actuator allows continuous operation even if dropped to the ground.


This Alarm is Extremely Powerful and the Volume of this Alarm Can Damage Hearing.

Please Use Sensibly and Away from Ears!

Why should I use a Personal Attack Alarm?

Personal alarms are a great way to increase your personal protection and safety. They have proven to be a useful tool time and time again.

If you carry a personal attack alarm it does not guarantee that you will be free from harm. However, what an alarm does give you is an improved chance of escaping the danger before the situation escalates.

It is important to choose a personal attack alarm that you feel comfortably carrying

Single Button Activation

With this alarm there are no rip cords or over complicated techniques when sounding the alarm. It is a battery operated, no wires, single button press which will then sound the alarm to deter attackers or signal you’re in need of help.

140dB of Alarmed Sound

This alarm will sound 140dB which is as ear peircing as a gunshot or fireworks and even louder than a police siren at 110dB. Sounding this level of volume is perfect for high risk roles such as lone workers or people who walk home late at night where an attack is more likely.

5 Year Guarentee

This alarm comes with a SURE24 5 year guarantee meaning we can replace, repair or assist you with your device to ensure complete peace of mind when purchasing and using this product. With over two decades of experience with personal alarms we know you’ll love this alarm.
