Hello
Happy Halloween!
Costumes, candy, burning pumpkins - what's not to love?
Hmmm ... I usually just toast my pumpkin seeds in the oven.

3101B Delayed Egress Maglock
Our industry is constantly faced with the issue of life safety versus security. We have a responsibility to insure
that building occupants can easily escape during a fire emergency while maintaining some measure of security. A typical
scenario would be a rear emergency exit door. That type of opening is not meant to be used as a casual exit. Problem
issues include health care facilities where a patient may wander out into harms way. Back door theft is common in
retail stores, restaurants, museums; almost any commercial or institutional building. So how do we add security
to these openings?
The NFPA 101 Life Safety Code has a section called Special Locking Arrangements. This allows us to delay the
egress through doors in certain locations and situations. The safety side - the system must be tied to the fire
panel system. The security side - an alarm is sounded, and the door won't unlock for 15 seconds (30 second when
approved). This provides the management of a building time to react before the door unlocks. The door will
unlock when the delay times out.
Tech Tips
FAQs about the 3101B
What's the difference between 3101, 3101A and 3101B?
3101 and 3101A are the same unit. It's the previous generation which has a ring and pin style sensor. The 3101B is
our current production model, with a new self adjusting roller-ball type sensor and a host of other improvements. The
system of operation is very similar for both models. It is best to use the 3101B as the 3101/3101A will eventually
be discontinued.
How is the delayed egress activated?
The armature (steel plate on the door) has some play built-in. When the door's hardware is unlatched, the door
remains locked by the 3101B but its sensor detects the movement, setting off the alarm and delayed egress timer.
Remember the good news - you can leave the existing latching hardware.
Can I hook up more than one unit on a single fire alarm relay?
Yes. You need to set all locks for NO on the FAC SELECT and wire all of the lock's 3 & 4 terminals in parallel to
the NO & C on the fire alarm's relay. Its imperative to maintain polarity by keeping all 3's together and all 4's
together. Another option is to drop power to all locks by cutting off the power supply, via the fire panel.
How do I control the unit with a keypad or access system?
The 3101B needs to have constant power on terminals 1 & 2. You should only drop power during an emergency. Remote
bypass terminals on the lock are provided to wire directly to any relay of a keypad, access panel or other access
device.
