Altronix Maximal77 Installation Instructions - Manual (Page 5)

Maximal11/Maximal33/Maximal55/Maximal77/Maximal75 Access Power Controllers (Fused) - 5 -
(b) Fail-Secure Switched Power outputs:
For Fail-Secure operation connect the positive (+) input of the access control devices to terminal marked [NO].
Connect the negative (-) input of the access control devices to terminal marked [COM].
(c) Form “C” outputs:
When form “C” outputs are desired the corresponding output fuses (1-8) of each ACM8 board must be removed.
6.
Auxiliary Power outputs (unswitched):
Connect access control devices that require constant power to terminals marked [C] positive (+) and [COM] negative (-).
7. Input trigger options (Fig. 2, pg. 9):
(a) Normally Open [NO] input trigger:
Inputs 1-8 are activated by normally open or open collector sink inputs.
Connect access control panel outputs, keypads, push buttons, REX PIRs, etc. to terminals marked [IN] and [GND].
(b) Open Collector Sink inputs:
Connect the access control panel open collector sink positive (+) to terminals marked [IN] and the negative (-) to
terminals marked [GND].
8. Fire Alarm Interface options (Figs. 10-15, pg. 17):
A normally closed [NC] or normally open [NO] input trigger from a fire alarm control panel or a polarity reversal
input from an FACP signaling circuit will affect selected outputs. To enable FACP Disconnect for an output
open the corresponding switch(es) [SW1-SW8] on each ACM8 board. To disable FACP disconnect for an
output close the corresponding switch(es) [SW1-SW8] on each ACM8 board.
(a) Normally Open [NO] input:
For non-latching hook-up refer to (Fig. 12, pg. 17). For latching hook-up refer to (Fig. 13, pg. 17).
(b) Normally Closed [NC] input:
For non-latching hook-up refer to (Fig. 14, pg. 17). For latching hook-up refer to (Fig. 15, pg. 17).
(c) FACP Signaling Circuit input trigger:
Connect the positive (+) and negative (-) from the FACP signaling circuit output to the terminals marked [+ INP -].
Connect the FACP EOL to the terminals marked [+ RET -] (polarity is referenced in an alarm condition).
Jumper J3 must be cut (Fig. 11, pg. 17).
9. FACP Dry form “C” output (Fig. 2a, pg. 9):
FACP form “C” contacts can be use to trigger reporting or signaling devices. These contact switch
upon a fire alarm input trigger to the ACM8 boards.
10. Stand-by Battery Connections (Figs. 3-5, pgs. 10-12):
For Access Control applications batteries are optional. If batteries are not used a loss of AC will result in the loss of
output voltage. Batteries must be lead acid or gel type. Connect one (1) 12VDC battery to the terminals marked
[+ BAT -] for 12VDC operation (Figs. 3, 5, pgs. 10, 12). Use two (2) 12VDC batteries wired in series for
24VDC operation (Figs. 3-5, pgs. 10-12).
11. Battery and AC Supervision outputs (Figs. 3-5, pgs. 10-12):
It is required to connect supervisory trouble reporting devices to outputs marked [AC Fail, BAT FAIL] supervisory
relay outputs marked [NC, C, NO] to appropriate visual notification devices. Use 22 AWG to 18 AWG for
AC Fail & Low/No Battery reporting.
12. Installation of tamper switch (Not Included) (Figs. 3a, 4a, 5a, pgs. 10-12):
Mount UL Listed tamper switch (Sentrol model 3012 or equivalent) at the top of the enclosure. Slide the tamper
switch bracket onto the edge of the enclosure approximately 2” from the right side. Connect tamper switch wiring to
the Access Control Panel input or the appropriate UL Listed reporting device. To activate alarm signal open the door
of the enclosure.
13. Multiple power supply inputs (Fig. 2, pg. 9):
When using an additional UL Listed external power supply, jumpers J1 and J2 located on corresponding
ACM8 boards must be cut (Fig. 2b, pg. 9 & Fig. 10, pg. 17). Connect external UL Listed power-limited access
control power supply to the terminals marked [- Power +] (only applicable on Maximal11). When using DC power
supplies polarity must be observed. When using AC power supplies polarity need not be observed. All field wiring
connections must be made employing suitable gauge CM or FPL jacketed wire (or equivalent substitute),
(Fig. 6a-9a, pgs. 13-16).
