Phone Line
Phone line trouble voltage: Trouble condition occurs when the phone line voltage is between 1.10 V and 4.75 V
Control Panel Power Requirements
AC Input Line Voltage
Use a UL Listed 18 V Class 2 transformer (22 VAC, VA 50/60 Hz), or the EZPS
Power Supply (not investigated by UL).
Total Alarm Power: 1.4 A (AC power and standby battery; intrusion applications only).
With a 7.0 Ah battery, the following current draws apply to all outputs and devices
connected to the system:
• Up to 170 mA for 24 hr for fire and combined fire/burglary applications
• Up to 400 mA for 4 hr for UL burglary applications
• Up to 1.2 A for other applications (not investigated by UL)
Auxiliary Power: 12 VDC, 1.0 A maximum. Includes 110 mA for each control center connected to the
system, and up to 400 mA for the programmable outputs.
Current Draw: 85 mA standby; 160 mA alarm with all outputs activated
Voltage: 12 VDC nominal (11.2 VDC to 12.3 VDC)
The control panel stops processing point faults when the voltage drops below
9.5 VDC.
Battery:
• D126 (7 Ah) or D1218 (18 Ah) sealed, lead acid rechargeable
• 1.7 A maximum recharging current
• Low battery condition occurs when battery drops below 12 VDC
• If AC power fails and the battery drops below 9.5 VDC, the control panel stops
processing point faults. Disconnect the battery under these conditions.
• Maximum auxiliary current to recharge standby battery within 72 hours:
- 12 V, 7 Ah Battery: 400 mA
-
12 V, 18 Ah Battery: 900 mA
EZPS Power Supply Requirements (not investigated by UL)
AC Input:
• AC Input Voltage: 100 VAC to 240 VAC
• Line Voltage Frequency: 47 Hz to 63 Hz
• Maximum Input Current: 0.5 A
• Power Factor: Approximately 0.65 at full load
DC Output:
• Nominal Output Voltage under AC line input: 18 VDC
• Output Voltage Range under AC line input: 16 VDC to 20 VDC
• Continuous Rated Output Current: 1.25 A
• Output Current Limit: Approximately 1.75 A to 2.5 A
• Periodic and Random Deviation (PARD): Less than 250 mV
DX2010 Input Expander
Operating Voltage: 8 VDC to 14 VDC
Current Draw: 35 mA standby; 135 mA maximum with connected accessories
Outputs: 100 mA, 12 VDC supervised output for accessories
Sensor Loop Terminal Wire Size: 0.8 mm (#22 AWG) to 1.8 mm (#14 AWG)
Wire Length:
• Control panel to DX2010 (DX2010 auxiliary output not used):
- 0.8 mm (#22 AWG) = 305 m (1000 ft)
- 1.2 mm (#1.2 mm) = 610 m (2000 ft)
• Control panel to DX2010 (DX2010 auxiliary output supplying 100 mA):
- 0.8 mm (#22 AWG) = 30 m (100 ft)
- 1.2 mm (#1.2 mm) = 76 m (250 ft)
Operating Temperature: +0°C to +50°C (+32°F to +122°F)
Relative Humidity: 5% to 85% @ +30°C (+86°F)
Sensor Loop Resistance:
60 Ω maximum
Sensor Loop:
Up to eight inputs; input contacts can be normally open (NO) or normally closed
(NC) with appropriate EOL resistors for supervision.
