INSTALLATION AND OPERATING INSTRUCTIONS

Fail Safe UnLatch FSUNL Series

1. INTRODUCTION
Securitron’s FSUNL-12 and FSUNL-24 are designed to work in conjunction with the UnLatch
family of products (UNL Series or MUNL Series). When interfaced with any UnLatch device the

FSUNL will allow the user to select specifically between “Fail Safe” or “Fail Secure” operation.

2. SPECIFICATIONS
Enclosure dimensions: 8”x6”x3” (inches) - Jumper selectable Fail Safe or Fail Secure operation.

Inrush current on power up:

Standby current:

1.45Amps for 3 seconds at 12VDC

90mA @ 12VDC at rest

1.2Amps for 3 seconds at 24VDC

140mA @ 24VDC at rest

Voltage Threshold: 12VDC

Voltage Threshold: 24VDC

Fail safe latch release @ 9.8VDC

Fail safe latch release @ 20VDC

Fail safe latch re-secure @ 10.8VDC

Fail safe latch re-secure @ 22.5VDC

3. RECOMMENDED TOOLS

Standard and Phillips Screwdriver

Drill Motor (optional)

Crimping Tool and Connectors

Digital Multi-Meter or Volt Ohm Meter

Wire Stripper

4. INSTALLATION INSTRUCTIONS
The FSUNL should be mounted indoors in an area protected from tampering (i.e. electronics
closet or above the drop ceiling at the opening) if possible. The board and enclosure can also be
surface mounted to the wall above the opening. For the most attractive surface installation the

cabling to the device should be run through the wire access port on the back of the enclosure
right into the wall. If this is inconvenient, or esthetics is not a concern the knock out on either
side of the enclosure (cover) can also be used.

5. OPERATIONAL INSTRUCTIONS
Once wired, as shown in the diagram below, the FSUNL will operate in the following manner: 1)
If the jumper selector is set to Fail Safe operation and the power to the system is lost the

capacitor energy reservoir will discharge and the trigger input on the UNL/MUNL will be initiated
driving the device through it’s cycle to the point were the door is unlocked. 2) If the jumper
selector is set to Fail Secure and power to the system is lost the capacitor energy reservoir will
discharge and the trigger input on the UNL/MUNL will be initiated driving the device through it’s
cycle to the point were the door is locked.

Definition of terminal strip:
+IN = Positive 12 or 24VDC continues input +OUT = Positive 12 or 24VDC continues to UNL
TI = Trigger input from external switch

- = Negative 0VDC continues reference

TO = Trigger out to UNL
