Part I, Part II and with all local codes and authorities having jurisdiction. Product is intended for indoor use only.
Power Supply Board Terminal Identification (pg. 5)
Power Supply Stand-by Battery Specifications (pg. 5)
Power Supply Board LED Diagnostics (pg. 6)
Power Supply Board Output Voltage Settings (pg. 6)
1. Mount unit in desired location. Mark and predrill holes in the wall to line up with the top three keyholes in the
enclosure. Install three upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s
upper keyholes over the three upper screws; level and secure. Mark the position of the lower three holes. Remove the
enclosure. Drill the lower holes and install the three fasteners. Place the enclosure’s upper keyholes over the three
upper screws. Install the three lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 9).
2. Connect unswitched AC power (120VAC 60Hz) to terminals marked [L, N] (Fig. 2, pg. 7). Use 14 AWG or
larger for all power connections. Secure green wire lead to earth ground. Keep power-limited wiring separate from
non power-limited wiring (120VAC 60Hz Input, Battery Wires). Minimum 0.25” spacing must be provided.
For Fire Alarm applications the outputs are “Special Applications” only, see list (refer to Appendix A, pg. 9).
Keep power-limited wiring separate from non power-limited wiring. Minimum 0.25” spacing must be provided.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
3. Select desired DC output voltage by setting SW1 to the appropriate position, (Maximal11FE, Maximal13FE,
Maximal33FE, Maximal35FE and Maximal37FE) (Fig. 1a, pg. 6). Maximal55FE power supplies are factory set at
12VDC. Maximal77FE power supplies are factory set at 24VDC. Maximal75FE power supplies are factory set at
12VDC and 24VDC, (Power Supply Board Stand-by Battery Specifications, pg. 5).
4. Measure output voltage before connecting devices. This helps avoiding potential damage.
5. Connect devices or Altronix sub-assembly modules to be powered to the terminals marked [-- DC +] (Fig. 2, pg. 7).
For auxiliary device connection, this output will not be affected by Low Power Disconnect or Fire Alarm Interface.
Connect device to the terminals marked [+ AUX -- ] (Fig. 2, pg. 7). Refer to page 2 for non power-limited applications.
6. 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.
Connect battery to the terminals marked [-- BAT + ] (Fig. 2, pg. 7). Use two (2) 12VDC batteries connected in series for
24VDC operation (battery leads included). Use batteries - Casil CL1270 (12V/7AH), CL12120 (12V/12AH),
CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or UL recognized BAZR2 batteries of an appropriate rating.
7. Connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 2, pg. 7) supervisory
relay outputs.
8. To delay AC reporting for 2 hrs., set dip switch [AC Delay] to OFF position (Fig. 2, pg. 7).
To delay AC reporting for 1 min., set dip switch [AC Delay] to ON position (Fig. 2, pg. 7).
Note: Must be set to ON position for Burglar Alarm Applications.
9. To enable Low Output Power Shutdown, set dip switch [Shutdown] to ON position (Fig. 2, pg. 7).
To disable Low Output Power Shutdown, set dip switch Shutdown] to OFF position (Fig. 2, pg. 7).
10. Trigger terminals are end of a line resistor supervised (10k ohms). Opening or shorting trigger terminals will cause
[DC] output to shutdown (Fig. 2, pg. 7).
11. Place a jumper for non-latching FACP. A momentary short on these terminals resets FACP latching
[Trigger EOL Shutdown] (Fig. 2, pg. 7).
12. For Access Control Applications: mount UL Listed tamper switch (Sentrol model 3012 or equivalent) at the top of the
enclosure. Slide tamper switch bracket onto the edge or the enclosure approx. 2” from the right side (Fig. 2a, pg. 7).
Connect tamper switch wiring to the Access Control Panel input or the appropriate UL Listed reporting device.
13. Please ensure that the cover is secured with the provided key 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
(MaximalFE Configuration Chart, pg. 3).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage at
the battery terminals and at the board terminals marked [-- BAT +] to ensure that there is no break in the battery
connection wires.
Note: Maximum charge current 1.54 amp.
Expected battery life is 5 years; however, it is recommended to change batteries within 4 years or less if necessary.
