Installing the SIM Gateway
Installation Guidelines
The following guidelines should be considered when planning the installation:
Function Guideline
Minimizing Voltage
Drop
Where an appreciable number of system horn/strobes or other high-
current devices are involved, consider using a dual run of the gateway
trunk cable. If a dual cable run is being used, try to locate the gateway
so that the sensor load will be evenly distributed between the two runs.
Gateway Location Make sure the SIM gateway is:
•
As close as possible to any horn/strobes or other heavy loads.
•
Within the protected area near points of protection.
•
Not mounted on temporary walls or partitions.
•
Protected from physical damage.
•
Mounted in an area free from excessive vibrations, corrosive
atmospheres, and temperature extremes.
Minimum Voltage to
SIM Gateway 12.1VDC with a fully charged battery and AC power applied to the
control unit, or to an external power supply, if used. (8.4VDC at end of
standby time).
Maximum RS-485 Bus
Length from Control
Unit to Gateway 4000 feet. This distance may be less to comply with the minimum
voltage to the SIM gateway.
Total Length of
Gateway Trunk Cable Must not exceed 1000 feet. This length may be less to comply with
minimum voltage to farthest SIM sensor. If using a dual trunk run, limit
applies to the sum of both runs.
Maximum Cable
Length to SIM Sensor 100 feet.
Note: T-tapping to an existing cable without cutting the existing cable is
permitted and will not adversely effect supervision.
Minimum Voltage to
Farthest SIM and
Sensor 12.0VDC with a fully charged battery and AC power applied to the
control unit, or to an external power supply, if used (8.3VDC at end of
standby time).
Gateway Log Form As a part of the installation, complete the Gateway Trunk log Form
shown previously in this section. When the form has been completed,
make a duplicate copy. Store one copy in the control unit and file the
other copy in the office.
Maximum Current
Draw from Gateway
Trunk
Black and Red wires: 1.0A; Blue and Yellow wires: 128mA.
Mounting the SIM Gateway
To mount the SIM gateway, perform the following steps:
Step Action
1 Locate the SIM gateway as outlined previously under the installation guidelines.
2 Mount the housing unit on a wall at the intended location using the two #8 screws in the
holes provided, making sure that its hinge is level and that the cover opens upward.
Note: If the housing unit is being mounted near a ceiling, and the wire rims exit the
ceiling, the box can be inverted. The ADT label supplied with the box can be placed over
the inverted molded logo. Now the wire runs can go directly to the box from the ceiling,
and not around the box.
3 Insert the gateway in the housing and depress the board until the locking catch snaps
over the PC board edge. Gateways are easily removed by depressing the locking catch.
