Lock stile mounting screws 10 Tighten hinge stile mounting screws on channel end cap MEL Wiring and Configuration (page 1 of 4) If not wiring at this time, DO NOT DISCARD CABLE! After installing device or conversion kit, if there is room, store the cable inside the channel until the electrical wiring occurs. Otherwise, store the cable in a designated location. Refer to table below to route proper gauge wires (from electric hinge, EPT, or door loop) to PS900-Series power supply. 11 Drill wire access hole in device channel and door. ⁵⁄₈" Dia. 12 Route MEL cable thru device. Route furnished 6’ MEL two-piece cable thru device end mounting bracket to connect MEL device to power transfer wires. connect to power transfer wires 13 Plug cable connector into MEL motor. c 3 MEL Wiring and Configuration (page 2 of 4) WARNING To avoid risk of electric shock, turn off AC power to power supply before installing or wiring option board. 14 Complete Wiring MEL device used with EPT, Electric Hinge, or Door Loop PS900-Series power supply with 900-Series option board(s) installed Distance (one way) Wire Gauge 200’ 18AWG 320’ 16AWG 500’ 14AWG 800’ 12AWG MEL Electrical Load Power wires to MEL are not polarized. 4 Voltage: 24 VDC Current: 1.0 A inrush (0.5 sec) 0.14 A holding electric hinge shown (an EPT or door loop may also be used) MEL exit device MEL Wiring and Configuration (page 3 of 4) 15 Confirm equipment compatibility MEL is compatible with the following equipment (refer to individual instructions as needed): • PS900-Series power supplies - PS902, PS904, PS906, PS914 • 900-Series option boards - 900-2RS, 900-4R, 900-4RL 16 Install 900-2RS, 4R, or 4RL option board(s) into power supply b Plug Option Board Cable into Review Available 900 series Option Board Mounting Locations (Gray) any Available Option Connector PS902 1 Board Option 1 a 1 PS904, 914 2 Boards Option 2 Option 1 PS902 PS904 PS914 1 Option 3 Option 2 Option 1 1 PS906 3 Boards 2 c Secure Board(s) with Screws WARNING Fire alarm (FA) option board required if MEL is installed in fire exit hardware. PS906 1 2 3 Notes: 1. 24 VDC output setting required when MEL device connected. 2. If installing board in location 2 or 3, rotate board 180˚. 3. Latchbolt retraction of (2) sequenced MEL devices requires more than 1 second to complete. 4. When powering multiple components, verify that the amperage requirements of all components combined does not exceed the power supply output rating. 5 MEL Wiring and Configuration (page 4 of 4) 17 Connect input and output wires to option board (2RS shown) Sequential Mode - Typical Wiring PS900 Series 120/240 VAC 50/60Hz 2RS Input I1 will activate both outputs SC I1 01 I2 02 GND EPT-2/10 Note: Fail secure output only allowed if approved by Authority Having Jurisdiction Individual Mode - Typical Wiring PS900 Series Access Control for Devices 1&2 120/240 VAC 50/60Hz 2RS SC I1 01 I2 02 GND EPT-2/10 MEL Device 1 MEL Device 2 Input I1 will activate output 1 Input I2 will activate output 2 EPT-2/10 Access Control MEL Device 2 for Device 2 EPT-2/10 Access Control MEL Device 1 for Device 1 18 Check operation a. Activate each input and verify all MEL devices operate properly. b. If any device does not operate properly, see next page for troubleshooting. 6 MEL Troubleshooting 19 If necessary, troubleshoot operation (LED is only visible with the mechanism case removed) Power at the MEL MEL Response Condition/Solution LED - solid green Latchbolt - retracted 24 VDC LED - flashing green Latchbolt - retracted 29 VDC or greater 13 VDC or lower 0 VDC Latchbolt cannot fully retract mechanically LED - solid red after latchbolt attempts to retract multiple times LED - flashing green/red Latchbolt - not retracted 24 VDC low Operation normal, latch retracted immediately LED- flashing red Latchbolt - will not retract LED - off Latchbolt - not retracted Remove power. Depress pushbar and make sure latchbolt retracts and extends fully. If necessary, disconnect any vertical rods or mortise lock from device center case, and reapply power. If motor holds, mechanical adjustments may be required per the device instructions.* Excessive tamper (while power applied, the pushpad was pulled out at least 3 times) Wait 15 seconds and latchbolt will retract again OR remove and reapply power to clear condition. Voltage low during latchbolt retraction (latchbolt retracts at reduced force) Wire length is too long, wire gauge is too small, or power supply has poor regulation. Input voltage is too high for proper operation Wrong power supply, power supply defective. Input voltage is too low for proper operation Wrong power supply, power supply defective or not set to the proper output voltage. To set, remove AC power from power supply, change power supply setting from 12 to 24 VDC, then reapply AC power and verify proper operation. No input voltage Problem with the power supply, control switch, or wiring. *For information about adjusting exit devices, you can find their installation instructions in the support area at www.allegion.com/us or call Technical Services at 1-877-671-7011 LED on device 7 20 Reinstall two end cap screws, end cap, and touchbar. 21 Reinstall hinge stile end cap and center case cover.
