Marks Hardware

New locks by Marks electrified mortise and cylindrical locks - They offer labor-saving electrified models in both mortise and cylindrical locksets in various functions, and for a variety of applications. Both mortise and cylindrical solenoid-operated locks in 12 or 24 VDC, Marks USA locks utilize solenoid actuators and are supplied with bridge rectifiers for use with either AC or DC current.

Features:

• Flexibility in ease of installation. Marks USA can offer dramatic savings in time and labor over electric strikes, and a cleaner installation, by wiring directly through the hinges. This eliminates the time-consuming requirement of cutting into cement-filled frames.
• Mortise models provide better security, with various modes of operation and lock information i.e., request to exit switch (REX), key override switch &/or latch bolt sensor
• Concealed latches for greater security - electrified mortise or cylindrical models are more secure than electric strikes, that have exposed latch keeper
• Fail-safe or fail-secure models – Ideal for stairwell doors with fire alarm system integration. (choose EU fail secure, electrically unlocked or EL fail safe, electrically locked)
• Cylindrical models with long life stainless steel retractor
• Mortise model with quick connect harness, with 2 convenient plug-in connectors for easy, quick wiring. One is always used; the second optional plug-in connector is used only with key position sensor.
• Request to exit and latch bolt-monitored options. Are frequently chosen, for example, to integrate with enterprise access control and/or "man-traps"
• 12VDC & 24 VDC compatible (AC rectifier module supplied)
