Use 18 AWG or larger for all power connections (Battery, AC input, DC outputs).
Use 22 AWG to 18 AWG for power-limited circuits (Trigger inputs, Dry outputs, DC outputs).
3.
Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Set the desired DC output voltage by setting switch SW2 to the appropriate position
(Power Supply Output Specifications Table, pg. 2, Fig. 1a, pg. 5).
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. 1, pg. 5).
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. 5).
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. 5). If required, set
the latching FACP interface mode by turning SW1 ON (Fig. 1, pg. 5) , 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. 2).
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.
