MaximalRDV Rack Access Power Controllers (PTC)
Installation Instructions:
Important:
Adjust output voltages and Fire Alarm Interface configuration before installing unit in the rack .
1 . Separate bottom and top of the rack mount chassis by removing six (6) screws
(Rack Mechanical Drawing and Dimensions, pg. 12) .
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.
2 .
Set output voltage:
Select desired DC output voltage by setting SW1 on the power supply board(s) (Fig. 1a, pg. 6) to the
appropriate position (Output Voltage and Stand-by Specification Charts, pg. 5) .
For Maximal33RDV each set of eight (8) outputs can be set for 12VDC or 24VDC
(example: eight (8) outputs @ 12VDC and eight (8) outputs @ 24VDC) .
3 .
Input trigger programming options:
The unit can be programmed to operate with either a normally open or normally closed input from access
control devices by setting switches SW3 on either the ACM8CBR-S or ACM16CBR-S board to the
appropriate position (Fig. 2b, pg. 7); OFF for a normally closed [NC] trigger input or ON for a normally
open [NO] input .
4 .
Output programming options:
a . The outputs can be programmed to be either all Fail-Safe (i .e . mag locks), all Fail-Secure (i .e . electric
strikes) or any combination of each by setting the corresponding OUTPUT SELECT dip switches (1-8)
on the ACM8CBR-S board to the appropriate position; ON for Fail-Safe outputs or OFF for Fail-Secure
outputs
(Fig. 2a, pg. 7) .
Note: the output configuration will follow the input trigger option
b . To enable the FACP Disconnect for an output the corresponding FIRE ALARM INTERFACE switch
must be in the ON position . To disable the FACP Disconnect the FIRE ALARM INTERFACE dip
switches (1-8) on the ACM8CBR-S/ACM16CBR-S board must be in the OFF position (Fig. 2a, pg. 7) .
5 .
Fire Alarm Interface hookup options:
A normally closed [NC], normally open [NO] input or polarity reversal from an FACP signaling circuit
will trigger the selected outputs (Figs. 6-11, pg. 9) . To program the Fire Alarm Interface set dip switches
SW1 and SW2 on the ACM8CBR-M board to the appropriate positions (Figs. 3a and 3b, pg. 7)
(Fire Alarm Interface Switch Settings pg. 5) .
6 .
Battery Connections:
For access control applications batteries are optional . If batteries are not used, a loss of AC will result in
the loss of output voltage . When batteries are used, they must be lead acid or gel type . Connect one (1)
battery to the terminals marked [– BAT +] for 12VDC operation . Use two (2) 12VDC batteries wired in
series for 24VDC operation (Fig. 4b, 5b, pg. 8) . The rack mount enclosure will not accommodate batteries .
A separate battery enclosure is required .
Note: When using the Maximal33RDV with battery backup, two (2) separate batteries or sets of batteries
must be used .
7 .
Battery and AC Supervision outputs:
Connect the appropriate notification signaling device to the terminals marked AC Fail and Battery Fail on
the power supply board(s) (Fig. 4a/5a, pg. 8) .
Use 22AWG to 18AWG for AC Fail and Low/No Battery reporting .
8 . Reassemble the bottom and top of the rack mount chassis by fastening the six (6) screws .
(Rack Mechanical Drawing and Dimensions pg. 12) .
9 . Attach mounting brackets to the rack mount Maximal for desired rack or wall installation (Fig. 12-14, pg. 10) .
10 . Mount in the desired rack location . Do not obstruct side air vents .
11 . Set the power disconnect circuit breaker to the OFF position (Fig. 15a, pg. 12).
12 . Plug power cord into a grounded 220VAC 50/60Hz receptacle (Fig. 15b, pg. 12) .
13 . Set the power disconnect circuit breaker to the ON position (Fig. 15a, pg. 12).
14 . Measure the output voltage before connecting devices . This helps avoiding potential damage .
15 . Set the power disconnect circuit breaker to the OFF position (Fig. 15a, pg. 12).
16 .
Input trigger connections:
Connect the Normally Open or Normally Closed input triggers from the access control devices to the
removable terminals marked [IN1 and GND] through [IN8 and GND] for Maximal1RHDV and
Maximal3RHDV . For Maximal1RDV, Maximal3RDV and Maximal33RDV connect devices to the second
set of terminals marked [IN1 and GND] through [IN8 and GND] . Make sure the devices match settings of
SW3 in step 3 (Rack Mechanical Drawing and Dimensions pg. 12) .
17 .
Output connections:
Connect the devices to be powered to the removable terminals marked [– OUT1 +] to [– OUT8 +] for
Maximal1RHDV and Maximal3RHDV . For Maximal1RDV, Maximal3RDV and Maximal33RDV connect
devices to the second set of terminals marked [– OUT1 +] to [– OUT8 +] (Fig. 15c, pg. 12) .
