he CareHawk CH1000 is a distributed, multi-channel, microprocessor-controlled security
communication system. The system architecture allows for up to a maximum of eight Security
Switching Cards (SS16), and eight display phones (DA1). Each SS16 contains 16 independent
output audio/device ports, and is designed to be remoted from the central cabinet.
Each SS16 can be located close to the central cabinet if desired, however to take advantage of the reduced
wiring requirements, it is typically remoted elsewhere in a facility. It can be anywhere from a few hundred
or a few thousand feet away from the central cabinet
1
. The system contains two independent 25V audio
channels which can be used for paging/program material distribution as well as intercom (when equipped
with an IA1 intercom amplifier).
The system is controlled via a Display Administrative Console (DA1). A CH1000 system can have up to
eight DA1s installed. Any # from 1 to a maximum of 8 of the phone ports are available for connection to
a PBX system via standard analog CO ports

. It is recommended that at least one of the ports be left
available for a DA1 when using multiple ports to interface with a PBX/KSU).
System Primary Component Overview
Central cabinet (CH1000)
The CH1000 is the central equipment cabinet for the security communication systems. Each
CH1000 provides for up to 128 audio/I/O ports and up to eight DA1 Display Administrative
Consoles, as well as the following connections on the MI100 Main Interface Card (See Figure 16
for location of all ports):
•
Six input and 5 open collector output contacts (via keyed terminal strips). Open collector
outputs are shared with two dry contact outputs (with N.O. and N.C. contacts available)
•
Any combination of phones or analog C.O. PBX interface ports totaling 8
•
One microphone port (terminal strip)
•
Two Music source inputs (terminal strip)
•
Ethernet connectivity (RJ-45 jack)
•
RS-485 port for driving external digital clocks (RJ-45 or terminal strip)

Attainable distances of the SS16 from the central cabinet are dependent on audio loading, and the losses deemed acceptable over
that distance.
