Description
The EM 6900 AM B used on mortise type of installation, requiring a filtered and
regulated DC Power source of correct voltage to attract the Armature plate and
when external pressure is applied to break that hold, the pivoting pin head fitted
into the Mechanical Electro Magnet slot holes will initiate a second locking
attempt from the upward movement of the magnet within the lock body to drag
out the six ball bearings to clasp firmly on the pivoting pin head with a superb
holding force of 8000 N and when power is removed the Mechanical Electro
Magnet would release its hold on the Armature plate and retract to its original
position as the bearing would roll back to release the clasp on the pivoting pin .
The EM 6900 AM B operates on 24V DC or 12V DC with two built-in SPST reed
switch sensor for remote lock monitoring status (Normally Open) on two non
polarity YELLOW output wires, and a remote door monitoring status (Normally
Open) on two non polarity BLUE output wires. The EM 6900 AM B consists of an
EARLY WARNING ALARM output C/NC/NO, Brown/White/Grey and a built-in
buzzer , to initiate warning before attempted break-in.
The DC output of the power supply must NOT be connected to earth ground, but
isolated to prevent shock and possible damage to the unit.
12V DC is not authorized for exit doors
Even a preload of 1000N is applied on the system
Buzzer can be disabled with the dip switch 4
