Operating
Voltage
10.2 - 14 VDC supplied by Aux Power
from Control Panel or an External
Auxiliary Power Supply.
Current 20 mA typical, 50 mA maximum
plus ≈ 60 mA for each EN4200 receiver
Operating
Temperature
+32°F to +149°F (0°C to +65°C), 93%
Relative Humidity
Wiring 18 AWG or 22 AWG Solid or Stranded.
Maximum distance from the control
panel to the commercial wireless
interface module cannot exceed 5 ft (1.5
m).
Maximum distance from
commercial wireless interface module to
EN4200 cannot exceed 100 ft (33 m).
Dimensions
(HxWxD)
3.94 in. x 6.5 in. x 1.2 in.
(10 cm x 16.6 cm x 3 cm)
For UL Listed installations, install the
commercial wireless interface module
within 20 ft (6 m) of, and within the same
room as, the EN4200 Serial Receiver.
1.4 Power
If the commercial wireless interface
module is powered down and then back
up, it may take up to a maximum of 5
minutes (Check-In Time is fixed at 3
minutes) for all the transmitters to report
back to the commercial wireless interface
module with their current status.
In addition, when the commercial wireless
interface module is powered up, all
programmed RF points will report Normal
until their state is updated.
The commercial wireless interface module’s power
should be connected to the control panel using the
Aux Power terminals. If the commercial wireless
interface module were to lose power, the following
conditions may result:
• All RF points will report to the control panel as
missing (trouble/alarm).
• All RF points will initialize in a normal state when
power is reapplied.
• Alarms initiated prior to power loss would be
reset. If the alarm conditions persist when power is
restored, new alarms would be generated.
Programmed settings such as RF point
configuration will remain intact upon the
event of a power loss.
1.5 System Supervision
1.5.1 Watchdog
The commercial wireless interface module implements
a watchdog software. Failure of the program will result
in a software reset within two seconds. This may cause
a trouble condition on the control panel for the
duration of the reset.
1.5.2 Self-Testing
The commercial wireless interface module EEPROM
memory is automatically tested on a periodic basis.
The EEPROM checksum is verified every ten minutes.
If the EEPROM checksum fails, a point bus trouble
condition will be seen at the control panel.
