Maximal Rack Access Power Controllers (Fused) Installation Guide
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 Maximal33R: 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 ACM8R-S or ACM16R-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 ACM8R-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 ACM8R-S/ACM16R-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 ACM8R-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 Maximal33R 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 115VAC 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 Maximal1RH and Maximal3RH.
For Maximal1R, Maximal3R and Maximal33R connect devices to the second set of terminals.
Make sure the devices match settings of SW3 in step 3
(Rack Mechanical Drawing and Dimensions pg. 12)
.
