Access Power Controller
Rev. DSMaximal3FD_05192015
Maximal3FD Access Power Controller distributes and switches power to access
control systems and accessories. It converts a 120VAC 60Hz input into sixteen
(16) independently controlled 12VDC or 24VDC power-limited PTC protected
outputs. The outputs are activated by an open collector sink or normally open
(NO) dry trigger input from an Access Control System, Keypad, Push Button,
REX PIR, etc. Unit will route power to a variety of access control hardware
devices including: Mag Locks, Electric Strikes, Magnetic Door Holders, etc. The
FACP Interface enables Emergency Egress, Alarm Monitoring, or may be used to
trigger other auxiliary devices. The fire alarm disconnect feature is individually
selectable for any or all of the sixteen (16) outputs. All interconnecting equipment
must be UL Listed.
Overview
Input:
• 120VAC 60Hz, 3.5 amp input.
• Power supply input options:
a) Two (2) common power input for either ACM8CB
and lock power (factory installed).
b) Two (2) isolated power inputs (external power
supply is required). Current is determined by
the power supply connected, not to exceed
a maximum of 10 amp total.
• Sixteen (16) Access Control System trigger inputs.
Input options:
a) Sixteen (16) normally open (NO) dry trigger inputs.
b) Sixteen (16) open collector inputs.
c) Any combination of the above.
Output:
• 12VDC or 24VDC power-limited outputs.
• Maximum output current:
12VDC @ 4.6 amp or 24VDC @ 5.2 amp.
• Sixteen (16) independently controlled outputs.
Output options:
a) Sixteen (16) Fail-Safe filtered power outputs.
b) Sixteen (16) Fail-Secure filtered power outputs.
c) Any combination of the above.
• Sixteen (16) auxiliary power outputs (unswitched)
(outputs are rated 2 amp).
• Filtered and electronically regulated outputs (built-in
power supply).
• Thermal and short circuit protection with auto reset.
Fuse Ratings:
• Power Supply input fuse rated @ 5 amp/250V.
• ACM8CB boards main fuse is rated at 10 amp.
PTC protected outputs are rated @ 2 amp each.
Supervision:
• AC fail supervision (form “C” contacts).
- Notification trigger is selectable for
30 seconds (factory set) or 2 hours.
• Battery fail and presence supervision (form “C” contacts).
Supervision (cont’d):
• Low power shutdown. Shuts down DC output terminals
if battery voltage drops below 71-73% for 12V units
and 70-75% for 24V units (depending on the power
supply). Prevents deep battery discharge.
Features:
• Fire Alarm disconnect (latching or non-latching) is
individually selectable for any or all of the
sixteen (16) outputs.
• Fire Alarm disconnect input options:
a) Normally open (NO) or normally closed (NC)
dry contact input.
b) Polarity reversal input from FACP signaling circuit.
• Alarm output relay indicates that FACP input is
triggered (form “C” contact rated @ 1 amp 28VDC).
Battery Backup:
• Built-in charger for sealed lead acid or gel type batteries.
• Maximum charge current 1.54 amp.
• Automatic switch over to stand-by battery when AC fails.
• Zero voltage drop when unit switches over to battery
backup (AC failure condition).
Visual Indicators:
• Red LEDs indicate outputs are triggered
(relays energized).
• Green LED indicates FACP disconnect is triggered.
• AC input and DC output LED indicators.
Electrical:
• Operating temperature: 0º C to 49º C ambient.
• BTU/Hr.:
- 12VDC: 28.25 BTU/Hr.
- 24VDC: 63.88 BTU/Hr.
• System AC input VA requirement: 420VA.
Mechanical:
• Enclosure Dimensions (H x W x D approx.):
26” x 19” x 6.25” (660.4mm x 482.6mm x 158.75mm).
• Enclosure accommodates up to four (4) 12AH batteries.
• Product weight (approx.): 32.15 lbs. (14.6 kg).
• Shipping weight (approx.): 39.3 lbs. (17.8 kg).
