This hardwired component based single door access control system was installed on an interior door to control access into an executive conference room. In addition to the very large wooden table with leather chairs surrounding, the conference room holds the latest in electronics including computer system, telephone conferencing, large screen HDTV and an espresso machine.
The single entry, wood, non-fire rated interior door with glass panel is equipped with a very old mortise lock. A decision was made to install an electrified mortise lock. Running power to the mortise lock requires drilling a raceway through the door.
A standalone keypad was selected to control access into the conference room. Since only a few key people need access, advanced features like audit trail and time-date access limitation were not required.
The hardware chosen to be installed for this single-door access control system is:
Altronix 125ULX Power Supply
Belden Wire jacketed two conductor 18 gage stranded cable
Camden Door Controls CM-8PS Fluorescent Self-Contained Keypad
Command Access ML180 Electrified Mortise Lock
Command Access ETH2W Power Transfer Butt Hinge
The Camden Door Controls CM-8PS keypad is designed for light to medium duty applications. This self-contained 12VDC/VAC keypad has a consumption maximum of less than 100mA (0.1 Amp). The keypad and electronics are installed into a compact polycarbonate enclosure, designed for indoor applications.
The telephone style keypad’s 12 clear buttons (1-10, triangle and square button) are backlit. All programming is completed at the keypad. Three LEDs indicate status. The green LED indicates when relay one is activated. The red LED indicates when relay two is activated. The yellow LED illuminates when pressing a button, in programming mode and if there is a data error in the programming mode.
The CM-8PS has a Master Code and eight programmable User Codes. The codes are five digits in length. The only additional programming is the time delay for the latched output. The choice is from one to 99 seconds for the momentary output time.
To attempt to prevent unauthorized access, after six incorrect code entries, the keypad jams for 30 seconds.
Each of the keypad’s two relays is operated by four user codes. For dual operation, the same user code can be programmed to operate both relays. For this installation, only one relay is required to power the mortise lock’s solenoid.
The Command Access ML1 Series Grade one electrified Mortise Lock is being installed to replace the mechanical mortise lock. These mortise locks feature continuous duty 12 or 24 volt solenoids. Depending upon the application, the ML1 Series lock can be field configured to Electrically Lock (Fail Safe) or Electrically Unlock (Fail Secure) the outside lever. The ML1 Series mortise lock’s two-wire lead has a plug-in bridge rectifier that accommodates an AC or DC power supply. In addition, ML1 Series locks are available with options including REX, LBM, DPS, SLM and CRU2i.
Fail Safe mode is used where the mortise lock requires power to remain locked. When power is removed, the lock unlocks providing access. Fail Secure mode is used where the mortise lock requires power to unlock. Electronic access is granted only when the lock is powered.
The ML1 Series id available in five functions including Storeroom ML180, Institutional ML182, Classroom ML170, Entry with deadbolt ML153 and Privacy with deadbolt ML148. These mortise locks are compatible with Schlage “L9000” Series trim. For this installation, the rose trim will be a compatible retrofit.
For this installation, the mechanical mortise lock is being replaced with a Command Access ML180 Electrified Mortise Lock equipped with a 12 Volt solenoid. Power is required for this Storeroom function mechanical lock to release the outside lever. The inside lever is always free for egress. The latchbolt can be retracted using the proper key from the outside.
