It is a universal fact that magnetic locks do not work or function on their own, since they rely on electric power and work in conjunction with the access control devices. These devices help the user in building security system at their work place or at resident. These devices work in such way that they build security in the building and allow or deny access to a location. A Maglock is best for those who are bad at leaving the keys behind or forgetting the key before leaving to the work place. Since there is no need of any key to operate magnetic locks, everything is accessed with card or digital keypads.
This device is totally dependent upon the electricity or Maglock power supply it requires a separate power supply 12V DC normally 1.5-2 Amps. A Maglock is powered from the separate power supply and the relay is connected to your control box lock output. Basically, the relay is used to cut the power to the Maglock when the door opens for few seconds, but when the magnet re-energies, it automatically grabs the armature plate on closing. A few seconds of opening the door are sufficient to cut the supply of power to the lock.
A relay has a power side that integrates the control boards of 12V DC/24V DC Maglock power supply output to energies the relay coil and therefore either makes a set of contacts or breaks a set of contacts. In the case of your release is less than 4 seconds, then a timer relay is required. The 2Amp power supply is powered by a main feed and the rest which is negative goes directly to the Maglock, even as the positive goes to the lock passing through the closed contact of the relay while traveling.
It is very important to understand that power supply voltage to electrically operated devices must match the voltage needed by the device. For instance, if a magnetic lock requires 24 DC, then the power supply must give 24V direct current.
