One of there best known products found everywhere is" The Stopper " a Hinged plastic cover that is placed over Fire Alarm Manual Pull stations to prevent accidental and deliberate activation of Pull stations . Its very simple design and works well it can be used with and with out an electronic sounder to even further deter pranksters who attempt to pull a false alarm. In one case at Holy Family's School for At Risk Children in Turtle Creek Pa. where they where having troubles with a student who enjoyed causing false alarms during lunch time my self and a helper had no sooner put several up in cafeteria and school hall and stopped to take a break and we heard one of the covers going off and the 16 year old student was caught and facing felony risking of a catastrophe charges .
I even had a custom cover made for a Emergency Boiler shut off switch in a hallway of a school that was being pushed and the little fool wet his pants it was so loud besides being caught.
But with this in mind I had a Fire Chief express to me his concern that some one who needs to activate the pull station for a real emergency might become confused by the loud alarm in the cover and think they have activated the fire system when they had not done so. However having done a good bit of research I have not found one incident of this. If any one has would you please let me know. for now though I will keep using there excellent products to help prevent false fire alarms .
