Speed of alarm activation.

Greetings Cronapress Blogreaders, Cronapressman here with more tech tips.
Today I'd like to cover what we at Cronapress consider a very important issue. 'Speed of alarm activation'.
Let's just imagine for a moment that an affray incident takes place-
It's a one on one situation......
The assailant is bigger and stronger........
There's little are defending yourself and you have moments to reach out and strike the alarm strip before being wrestled to the ground.......
The strip is hit..........theres's no second chance !
                                                       But, the alarm hasn't sounded !
What's gone wrong ? The alarm is monitored for line faults so it should work !!!!!
Probability suggests that the alarm unit is a nurse call alarm or worse a reconfigured burgular alarm.
The electrical contact time needed to make one of these work would be in the region of 250mS.
Hey, how fast does it have to be Cronapressman? Well, there are no rules but you must surely want the best ? 250mS is a long time in an volatile situation. Try this experiment - Stand 1mtr from a wall, arm down by your side, reach out, strike the wall and drop your arm back to your side. How long did that take? I'll bet it took nearly 2 seconds. Imagine adding a full 1/4 second to that ! 12% extra !!!!!!

Cronapress have the answer - Our Intergrator has many functions but today we will look at it's activation speed. The Cronapress intergrator only needs a 5mS contact to latch!!!!!!
It's a must have where staff safety is an issue, and let's face it you wouldn't be fitting the affray strips if you were not serious on this matter.

The Cronapress Intergrator is faster than the fastest press!!! True!!!!
Toshiyuki Takahashi from Japan can push a button 16 times a second ! Phew, that's an amazing 62mS per push!
Here's a link to his video. Fastest Button Presser in the World  (but not as fast as a Cronapress latch!)

Tools of the Trade No1

Cronapressman here - I'm down in the workshop today and I thought I'd just take a few minutes out to show you our recommended cutting tool for the Feelsafe/Safezone insert. (In fact it works pretty good on the 'B' and 'CB' insert too.)
Measure and then mark accurately the cutting point, position the snips at 90degree to the insert and voila a quick snip and the jobs done !
Clean cut - accurate too !
Remember my motto ? -  If it looks right it will be right !   If it doesn't - you guessed it - it won't !

So ! What you waiting for ? Get it touch with me at Cronapress and order the right too for the job.
Don't forget - Keep checking the Cronapress Blogspot for more 'Top Tips' too....

Safezone fitting - Including an on site wall fix.

Greetings - Cronapressman here with some extra fitting tips to help you install Cronapress Safe-zone correctly and securely. For this post we will run through the various steps of instalation and also replicate a common on-site problem. Feedback from various alarm engineers suggests that crumbling walls/loose wall structure can be an issue which can result in ill fitment of the Safe-zone End-Cap and thus poor electrical continuity. (Examples of which have been posted on a previous blog.) The fix we illustrate is an example of how with fore-thought and an understanding of the components we can use easily sourced items/tools to achieve a good result.

No1 - Mark centre line of base on wall. Offer base strip into position and mark fixing hole position on centre line. (Should you be cutting to size on site ensure that new fixing holes are drilled within 80mm of base ends.)

No2 - In most instances drilling and fixing with quality wall plugs and appropriate size screws will be sufficient. However bear in mind the environment the alarm strip is being fitted into and upgrade fixings if risk of severe vandalism is likely to take place.

No3 - Fix base extrusion to wall.
No4 - Push end cap firmly into position and mark position of fixing holes.
No5 - Drill and plug as above.

Wall Problem - For this exercise we have deliberately enlarged a plug hole to replicate a crumbling/dry wall,
or possibly the drill bit was inappropriate for the plugs ? (Either way we need to construct a sound fixing.)

Our fix will involve the use of 2 part epoxy resin. All dust and debris needs to be cleaned from the bonding area before mixing the resin and applying into hole and around wall plug. A small brush is a suitable tool to remove all loose particles.

To stop the resin running out before fully cured we used adhesive tape to hold in place. This has the added benefit of forming a surface flush with the wall.

Above -Resin fully cured and adhesive tap removed. We can now continue with fitment of the Cronapress Safe-zone alarm strip.

No6 - Expose adhesive strip on reverse of L.E.D. strip, centre lights into either upper or lower channel of base rail and push lightly to bond.

No7 - Drop insert strip into lower lip of base rail and working from one end bend to feed top under upper lip.

No8 - Push Safe-zone End Cap connector tongue into strip, ensure 2 small extruding tabs locate under base and fix with screws into pre-fitted plugs.

Note - Insert strip cut 1mm shorter than base rail.
Note also - Insert fully covers electrical connection.
Step 9 - Test alarm strip for electrical continuity. Finally fix Safe-zone End Cap cover into position. The application of a 'Superglue' type adhesive in the pin holes will ensure not only a firm fixing but will maintain the strip electrical connection by virtue of the pushing effect on the insert by the caps underside.
