Maximal 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 rack mount chassis by removing six (6) screws (Rack Mechanical Drawing &

Dimensions, pg. 11).

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 Maximal33RD each set of eight (8) outputs can be set for 12VDC or 24VDC (example: eight (8) outputs @

12VDC and eight (8) outputs @ 24VDC).

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); OPEN for a normally closed [NC] trigger input or CLOSED for a normally open [NO] input.

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

ACM8CBR-S/ACM16CBR-S board must be in the OFF position (Fig. 2a, pg. 7).

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 & 3b, pg. 7) (Fire Alarm Interface Switch Settings pg. 5).

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 Maximal33RD with battery backup two (2) separate batteries or sets of batteries must be used.

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 rack mount chassis by fastening the six (6) screws.

(Rack Mechanical Drawing & Dimensions pg. 11).

9. Attach mounting brackets to rack mount Maximal for desired rack or wall installation (Fig. 12-14, pg. 10).
10. Mount in desired rack location. Do not obstruct side air vents.
11. Set the power disconnect circuit breaker to the OFF position (Fig. 15a, pg. 11).
12. Plug power cord into grounded 50/60Hz receptacle (Fig. 15b, pg. 11).
13. Set the power disconnect circuit breaker to the ON position (Fig. 15a, pg. 11).
14. Measure the output voltage before connecting devices. This helps avoid potential damage.
15. Set the power disconnect circuit breaker to the OFF position (Fig. 15a, pg. 11).
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 Maximal1RHD and Maximal3RHD. For

Maximal1RD, Maximal3RD and Maximal33RD connect devices to the second set of terminals marked. For Make

sure the devices match settings of SW3 in step 3 (Rack Mechanical Drawing & Dimensions pg. 11).

17.

Output connections:

Connect the devices to be powered to the removable terminals marked [-- OUT1 + to -- OUT8 +] for Maximal1RHD

and Maximal3RHD. For Maximal1RD, Maximal3RD and Maximal33RD connect devices to the second set of

terminals marked [-- OUT1 + to -- OUT8 +] (Fig. 15c, pg. 11).

18.

Fire Alarm Interface connection options:

a. Connect the FACP trigger input to the removable terminals marked FACP1 and FACP2. When using the polarity

reversal from an FACP signaling circuit, connect the negative [-] to the terminal marked FACP1 and the positive

to the terminal marked FACP2 (polarity is in alarm condition) (Rack Mechanical Drawing & Dimensions pg. 12).
