into the 6 threaded standoff locations in the Accelaterm in-
terface board shown on page 1. Then plug the
CICP2800EXPRDBD 8 Reader Expansion Board into the con-
nector located at the center of the interface board. Finally, in-
sert 6 screws (provided) into the 6 screw holes detailed in the
image below.
See installation instructions WI1989 for more information re-
garding the installation of the Accelaterm control panel.
SPECIFICATIONS
12VDC rated at 20mA.
Internally-Routed Power for
Locks 5-8 and 13-16
When the Eight Reader Expansion Board is added, relays 5-8
and 13-16 are normally used to control the locks. The control
may be with familiar dry contact power connected to each cir-
cuit, or field wiring can be greatly simplified by routing the
lock power through the Accelaterm Relay Board.
To the right of the center line on the Relay Board, find JP4
marked LOCK PWR IN [5-8] and [13-16]. A
9CICP2800AUXH Accessory Cable provides two pairs of con-
ductors for two power-limited circuits. The power supply may
be one or two UL603 or UL294 listed units. Normally battery-
backed, these may be 12VDC or 24 to 28VDC.
Considerations for use of 24VDC
Equipment
•
Magnetic locks drain half the current at 24V
than at 12V for the same holding force.
•
Losses in the wiring resistance are ¼ that of the lower volt-
age. This is significant if high-holding force locks must be
used.
•
Many UL294 / UL603 power supplies offer selectable
voltage, at the same current and cost.
