INSTALLATION

• 1. Verify lock compatibility, refer to page 2 and Fig. 6, page 4.
• 2. For proper frame preparation, refer to template drawings, Fig. 4 & 5, page 4.
• 2. Factory supplied in Failsecure mode. For Failsafe mode refer to Fig. 2, page 3
• 3. Determine minimum wire gauge required. See wire gauge chart below.
• 4. CAUTION! Before connecting power wires check for proper operating voltage at opening with a volt meter. Voltage must be within +/- 10% of strike operating voltage for proper operation.
• 5. Configure strike for 12 or 24VDC operation. Refer to pigtail power connector wiring in Fig. 1, Page 3 . Connect wires to power source.
• 6. To install the strike into the frame opening:
  • A) Position the wiring either down or up or toward the back of the hollow metal frame. Make sure wires are completely clear of strike, so they are not pinched when mounting strike in the frame.
  • B) Insert mounting screws through the faceplate and secure into mounting tabs.
• 7. After installation check horizontal alignment. There should be 1/32" allowable movement when the door is pulled toward the keeper.
• 8. ALIGNMENT ADJUSTMENT: Loosen mounting screws, shift strike body behind faceplate horizontally as shown in Fig. 3A, page 3 , then tighten mounting screws.
• 9. For excessive horizontal alignment issues, remove shim filer bar from the keeper as shown in Fig. 3B, page 3
• 10. The Electric Door Strike MUST be installed in such a way and in such a location so as not to impair the operation of an emergency exit or panic hardware mounted on the door.

Strike Input - Minimum Wire Gauge Requirements

OPERATION:

Fail-Secure (Power-to-Unlock): Unlocked when energized. Locked when de-energized and during power failure.

Application: For non fire rated and fire rated doors (exception, may not be used on stairwell doors). May not be maintained in the unlocked (energized) state when used with fire rated doors.

Fail-Safe (Power-to-Lock): Locked when energized. Unlocked when de-energized and during power failure.

Application: Non-fire rated doors only.

CAUTION: Fail-safe is not permitted with the UL Fire Door

Accessory label.
