I personally feel that the dual action pull stations are more effective in preventing false alarms due to younger people wanting to just activate the fire alarm system. However, I do not like the push in and pull types of pull stations since people don't pay enough attention. I prefer the lift and pull dual action pull stations since it is obvious.
Oh, and something that's interesting is that System Sensor (also owned by Honeywell) manufactures these pulls and then puts the various brands' logos and ID tag on. Because the 'SSD' inside stands for 'System Sensor Device'. Sorry about all the different comments lol.
In New Zealand, Fire Call Points are legally required to be dual-action. Most of our require you to either break glass or push in a plastic cover, then operate a switch-button. however, recently European ones have started appearing over here. These simply have a flap over them that you lift before pressing them in. You can actually make a call-point compliant in NZ by simply adding a call-point cover. lots of places use these anyway, making them effectively tri-action.
I've only seen the single action at a local Price Chopper (grocery store). The system is Silent Knight, and I actually think the single action may be more common for silent knight. The SK model is PS-SA (where the normal BG-12L would be a PS-DA). The hex lock ones add an H, PS-SAH and -DAH. The addressable models are IDP-PULL-SA and IDP-PULL-DA respectively.
Fire-Lite, Notifier, Silent Knight, and Gamewell-FCI are actually going to be consolidated into one brand apparently: Honeywell. Their logos will still be featured on these pulls, but they'll be really small (for example, the Honeywell logo in big letters on top) and the brand in small letters on the bottom (so basically they'll say something like: Honeywell (and below) (in smaller text) Fire-Lite Alarms. They are also phasing out certain panels and things as well.
You don't have to flip up the switch, there is a mechanism inside which flips it up as you close the door of the station. Honeywell designed it this way so that closing the station will reset the switch without breaking it.
Funny story. My sleepaway camp has gamewell single action pull stations, but it also has the wheellock ns as well in some areas. However most of the place has gentex commander 3's
I think the double action is bigger building and single action for smaller buildings. Fire Lite's addressable version of the BG-12 only comes in double action.
My school recently got one since they added a little area onto the building. They decided to put a fire alarm in it for some reason, can't say why but it's pretty weird.
I have replaced more of the dual action versions of these than I can count; switches fail a lot. The dual action mechanics yank on that plastic junk switch at an odd angle and they eventually break. Same result when closing without manually resetting the switch, it gets pushed up at an odd angle. When they fail the switch gets very spongy and moves sloppily and will not activate....kind of a big problem. This may be a slow process in most cases but the facilities I inspect do drills constantly and the lazy employees always use the same pull station.
single action tho is my preference. some kid rammed his backpack into a double action one in my school and accidentally set off a double action pull station
Did you know the single action and the double action when you Pull those you see a little black thing at the bottom on every single action in the double action pull station you see a black thing when you pull both of those in when were different brands to Like that
Not sure where this rumor comes from... Text from Silent Knight document 52155: *Resetting the Pull Station* 1. Insert the key into the lock and rotate 1/4 turn counterclockwise. 2. Open the door until the handle returns to normal. 3. Close and lock the door. *NOTE:* Closing the door automatically resets the switch to the ‘Normal’ position. Opening the door will not activate or deactivate the alarm switch. Manuals for the other Honeywell equivalents of this device say roughly the same thing.
