4 16 Zone Hardwired Input Module
To install the HWIM:
1. Carefully select the mounting location, verifying that the HWIM’s antennas are
pointing up, and then secure it in position using the provided screws and wall
anchors.
Note: The HWIM should be within 1000 ft (304.8 m) of the panel. Walls,
construction materials, and other objects may impede the signal and shorten
the distance.
2. Attach each antenna to the HWIM, placing one in each of the ANT terminals
on the top of the HWIM.
Note: The antennas should be clear of obstructions and if in a metal
enclosure, should extend outside of it.
3. Wire the sensors/leads to the desired terminals marked Zone 1 through 16.
Wiring Notes:
•The HWIM requires 4.7 kΩ of end of line (EOL) resistance on each zone.
Existing installations may already have EOL resistors installed. Determine
the current EOL resistance value and adjust as needed to get total
resistance to 4.7 kΩ.
•EOL resistor installation depends on if the sensor is normally open (N/O)
or normally closed (N/C). Refer to Determining EOL resistance and sensor
type on page 5, for details on determining EOL resistance and if a sensor
is N/O or N/C.
•Install one of the included 4.7 kΩ resistors to each zone with an attached
sensor. Install the resistor in parallel for N/O and in series with N/C
sensors.
•To provide power to powered sensors, such as motion and glass break
sensors, wire the Positive and Negative leads from the sensor to the
“AUX” (+) and “GND” (-) terminals. See Figure 4 and 5, on page 8.
4. Wire the tamper switch input.
Note: This is required for proper device operation.
Option 1: If using a tamper switch, wire the tamper switch directly to the
tamper terminals without the need for an EOL resistor.
Option 2: If not using a tamper switch, connect a jumper wire across the
tamper input terminals.
5. (Recommended) For any security system that is supervised, a battery should
be connected to the HWIM. To provide an independent battery back up to the
HWIM, connect the included battery leads to a 12VDC, 5Ah lead acid
rechargeable battery (battery not included). This battery type is common with
traditional hardwired security panels, otherwise it is recommended that you
connect the HWIM to an auxiliary 16VDC power supply (1 amp or greater)
with its own battery backup.
