ISDR1 connections
Cabling for ISDR1 modules in a ComPoint system
Installation
The ISDR1 Door Strike Release Module mounts on any flat
surface. Generally, if the module is used to activate a door
strike release, install it in an accessible location close to the
door, such as an attic, basement, or closet space. If the
module is used with a central security controller, locate it
near the controller or the ComPoint hub.
The ISDR1 can be located up to 250 feet (76 m) from the
hub. The cable distance between the ISDR1 and the sepa-
rate door strike release or gate actuator is determined by
the release or actuator manufacturer.
Wiring
ComPoint system components interconnect with CAT-5
cable. When running the door station CAT-5 cables, loop
them through the ISDR1 module locations.
For the connection with the separate door strike release or
other device, run two-conductor control cable between the
ISDR1 and the device being controlled.
When running CAT-5 and control cables, avoid running them
near AC power wiring. If you have to run the cables parallel
to electrical wiring, space the cables at least 2 feet (0.6 m)
from the AC power lines.
Connections
The ISDR1 provides 110 punch-down connectors for the
CAT-5 cables. Use a punch-down tool to connect the wires
according to the color code shown on the module.
The relay output terminals provide access to normally open
(NO) and normally closed (NC) contacts. Typically a door
strike release connects between the COM and NO termi-
nals. The NC terminal is available to provide an interruptible
signal path for other applications.
Operation
The ISDR1 obtains its operational power from the ComPoint
hub. It passes signals to and from the door station on all
leads of the CAT-5 cable except one, which is used to acti-
vate the module from the hub upon receiving a command
from a keypad. When activated this way, the ISDR1’s relay
remains active for 3 seconds.
The ISDR1 can also be activated by providing 15 VDC
between the orange/white (+) and green/white (–) terminals
in the input connector.
Note: The ISDR1 does not power the separate door strike
release or gate actuator. Any external device connected to
the ISDR1 must receive power from its own source.
