5. Connect Fail-Safe locking devices to the terminals marked [COM-- and LOCK+]. Connect Fail-Secure locking
devices to the terminals marked [COM-- and ] (Fig. 2, pg. 3).
6. Connect normally open access control device (i.e. cardreader, request to exit device, access control system) to the
terminals marked TRG INPUT [NO, GND] (Fig. 1 - Application Diagram, pg. 3).
7. Connect FACP interface to the terminals marked [FACP1 and FACP2]. Wire the 2.2K resistor (supplied) in series
for a normally closed input or in parallel for a normally open input (Fig. 1, pg. 3). If required, set the latching FACP
interface mode by closing SW1 (Fig. 1a, pg. 3), and connect a normally open reset device to the terminals marked
RESET [NO, GND].
8. Connect battery to the terminals marked [+ BAT -- ] (battery leads included). Use two (2) 12VDC batteries connected
in series for 24VDC operation.
Note: For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the
loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
9. Please ensure that the cover is secured with the provided cam lock.
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level
(Power Supply Output Specifications Table, pg. 1).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at battery
terminal and at the board terminals marked [- BAT +] to ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharge is 400mA.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
Terminal Identification:
Terminal Legend Function/Description
XFMR
Low voltage transformer connections.
+ AUX ---
Aux power output terminals. These terminals will supply 12VDC or 24VDC, not affected
by trigger, reset or fire alarm interface.
LOCK +,
,
COM ---
Switched power output. Fail-Safe [LOCK+] supplies positive power when unit is not triggered and
FACP interface is inactive. Fail-Secure [] supplies positive power when unit is triggered
and/or fire alarm interface is activated. [COM --- ] supplies negative power.
FACP1,
FACP2
Supervised by 2.2K end of line resistor FACP interface. Short or open will cause power to be
dropped to the terminal marked [LOCK+] and supply power to the terminal marked [].
Condition can be maintained even after restoration of the circuit (latching mode).
TRG INPUT,
NO, GND
Short between these two (2) terminals will cause power to be dropped to the terminal marked
[LOCK+] and supplied to the terminal marked [].
RESET,
NO, GND
Momentary short between these terminals would end latching FACP interface condition.
Feature active only if latching FACP is selected (SW1 closed).
--- BAT +
Stand-by battery connections.
