Square mortise electromagnetic door holder - with contact

24 VDC-50 DaN - EN1155 n° 0805501

Square mortise electromagnetic door holder - with contact

EN 1155 certification was assigned to these electromagnetic locks, made to be mortised into a 60 mm diameter outlet box to maintain the fire doors open. That is to say if these electromagnetic restraining devices are suitable for a mounting inside the buildings meeting the fire security standards.

A status contact is embedded in this VELMAG™ electromagnetic lock, enabling to send an information deferral to the fire signaling table on the aperture or closure of the door.

The breaking power of this contact rises up to 175V DC and 0.5 amperes at more.

Unlocked by power failure, the electromagnetic locks generate immediate closure of access in case of emergency, preventing the fire from spreading to the rest of the building. This is the fire signaling table which interrupts the power if it detects any source of fire. The safety of people is provided by the system, especially as a blackout will not prevent the fire door from closing, because the release is performed by power off.

The voltage supply is 24V DC, and the consumption is only 60 mA, which allows achieving important energy savings. Furthermore, this electromagnetic lock exclusively works with direct current, whose benefit is to minimize noise.

Included in the delivery, the counterplate can be mounted in fix or articulated position according to the installation. The connection of the square electromagnetic lock is done by one or more terminal blocks. Otherwise, the button for remote unlocking that comes along with the EN 1155 certified electromagnetic locks is not comprised and must be ordered separately.

In accordance with the IP 30 degree of protection, these mortise electromagnetic locks are protected against foreign solid objects taller than 2.5 mm. Their indicative holding force is 50 DaN, which is guaranteed at least 90% provided that the fitting conditions indicated by SEWOSY have been met.
