M8 / M8P Installation Manual

1
Zone Inputs (INPUT 1 – 8)
These are the input terminal strips. These terminals are remov-
able and accept wire sizes from AWG12 – AWG22. The terminals
are labeled on the PC board near the terminal strip. See the Input
Wiring section of this manual for more information.
• When using a dry contact input, the contact is connected
across the A and B terminals. It is normal to measure a
voltage across these two terminals. This voltage is cur-
rent limited and will not damage the activation contact.
• When using a voltage input, the voltage is connected to
the B terminal. The activation voltage must be common
grounded with the system voltage and must be between
12 and 24VDC. Leave the A terminal disconnected.
• When using an open collector input, place a jumper across
the A and B terminals and connect the open collector to B.
Note that the input source must be common grounded with
the M8/M8P board’s power source.

FlexIO Connectors
These connectors pass the FAI and Fault signals to and
from the M8/M8P board and pass the FlexIO buss on to
other accessory boards in the system.
3
Output Status LEDs (1 – 8) – Green/Blue
These LEDs indicate the status of the output. LED numbers
correspond with the zone number (e.g. LED 1 for Output 1).
When Powering Lock Devices:
• ON SteadyDoor Locked (Fuse or PTC Intact)
• SLOW Flashing (1 per second)Door Unlocked (Either
due to Zone Input or FAI)
• FAST Flashing (4 per second) Fault Detected on Zone
• OFFFuse or PTC open, or zone disabled in software
When Set for Constant Output:
• On SteadyOutput Powered (Fuse or PTC Intact)
• SLOW Flashing (1 per second)Output Unpowered (Due
to FAI)
• FAST Flashing (4 per second) Fault Detected on Zone
• OFFFuse or PTC open, or zone disabled in software
These LEDs are bi-color and indicate the output voltage for
each output as follows:
• Green – 12V Output
• Blue – 24V Output
I
NOTE LED colors are range based. Voltage Less than 13V
will show Green. Voltage above 20V will show Blue. Voltage
between 13 and 20 may show either voltage or a combination
Green & Blue. Always verify voltage with a voltmeter.
4
Fault LED (FAULT) – Yellow
This LED lights when the M8/M8P detects a ruptured output fuse
or other fault condition (including a tripped upper or lower limit
- See the programming section for more information). This fault
condition also transmits to the power supply through the FlexIO.
5
Buss Selection Yellow Jumpers (1-8)
The M8/M8P can accept up to two power inputs connected to
B1 and B2. This jumper selects which power supply input is
used for the output. If a single power supply is used, set this
jumper for Position 1.
B1 This position selects the power supply connected to B1
B2 This position selects the power supply connected to B2
6
Zone Outputs (0UTPUT 1-8)
These are the output terminals. These terminal strips are
removable and accept wire sizes from AWG12 – AWG22. The
terminals are labeled on the PC board near the terminal strip.
See the Output Wiring section for more information.
I
The M8 has reverse protection diodes across each output.
If a delay is present on lock release, the diode should be re-
moved from the circuit. See page 7 for more information.
7
Zone 8 Wet / Dry Output Selection (J26 - J28)
Zone 8 of the M8 is able to be set as a dry contact output. Fac-
tory default setting is all four jumpers set to "Wet". To set the
zone as a dry output, all four jumpers must be set to "Dry".
8
Output Fuses (F1 – F8) – Optional
When using the fused version of the M8, these are the fuses for
each zone output. Fuse numbers correspond with the zone (e.g.
F1 is the fuse for OUT1). When using the M8P (PTC) version,
these fuses will be replaced with soldered-in PTCs.
9
BR Connectors (J5 & J6)
The DC Common buss in the system. All DC boards in
the system must have their BR fastons wired together for
proper operation.
bk
B2 Connectors (J7 & J8)
These fastons are for connection to the B2 buss in the system.
The voltage on the B2 buss comes from a second power sup-
ply or a B100 secondary supply in dual voltage systems. This
voltage will be directed to any outputs whose Buss Selection
Jumper is set in the B2 position. If the M8/M8P is being used
in a single voltage system, these fastons are left unused.
bl
B1 Connectors (J1 & J2)
These fastons are for connection to the B1 buss in the
system. The voltage on the B1 buss comes from a the first
power supply. This voltage will be directed to any outputs
whose Buss Selection Jumper is set in the B1 position.
bm
SPI Connector (J13)
This connector accepts the SPI cable which provides com-
munication between the M8/M8P and the NL4 board. This
cable MUST be connected at all times for proper operation
of the M8/M8P. The M8/M8P must be connected to an NL4
board and will not function if connected to an NL2 board.
