AES Corporation 9 40-7788, Rev 6, August 30, 2016
1.8 Technical Specifications
SIZE: 13.25”h X 8.5”w X 4.3”d (34 cm X 21.5 cm X 11 cm) excluding antenna
WEIGHT: 5.8 pounds (2.6 kilograms) Without Battery (Add 6 pounds with Battery)
TRANSFORMER SECONDARY POWER INPUT: 16.5VAC, 40V / 45VA class 2 (dry)
source only
VOLTAGE: 12VDC nominal
MAINS INPUT CURRENT: 150 mA standby; 1.2A transmit
MAINS INPUT CURRENT with optional accessories: 210 mA standby; 1.3 A transmit
(2 Watt Transceiver)
OPERATING TEMPERATURE RANGE: 0° to 49° C (32° to 120°F)
STORAGE TEMPERATURE RANGE: -10° to 60° C (14° to 140°F)
RELATIVE HUMIDITY RANGE: 0 to 93% RHC, Non Condensing
BACK-UP BATTERY: 12V, 7.5AH – 12 AH (24 Hour standby), 1.2A Max.
(Min), lead acid gel type; required for all installations
BATTERY FUSE: Onboard self-resetting fuse. Not serviceable
ALARM SIGNAL INPUTS: 8 Supervised individually programmable Zones:
All 8 are EOL type with, Trouble & Restore
LOW BATTERY REPORTING: Below 11V. 22.5 Minute Test Cycle (approx..)
AC FAILURE REPORTING: AC Fail messages are queued for transmission to central
station after approximately 100 continuous minutes without AC power. Transmission to
central station is then delayed randomly between 0 to 60 minutes. Restore is similar with
Restore message queued for transmission after approximately 100 continuous minutes
with AC power restored. AC Fail/Restore messages will be sent between 100 and 160
minutes after the failure or restore occurs that remains for 100 minutes. See Section 4.3 -
Timing Parameters for additional information and programming options.
ANTENNA CUT / LOW BATTERY / CHARGER FAIL LOCAL REPORTING: Form
C Fail Secure Relay contact. Engaged for normal operation. Disengages on Reset,
Antenna Cut/Acknowledge Delay, total power loss condition, low battery or charger fail.
Contact rating – 24VDC 1-Amp max, Not Supervised
RESET BUTTON: Located on the PCB.
TRANSCEIVER:
Standard UHF Frequency Ranges (410-440MHz, 440-470MHz, 470-512MHz)
TRANSCEIVER FUSE: 400 milliamp PTC, Not serviceable
STANDARD RF OUTPUT POWER: 2 Watts
Zones 1-8: dry contact supervised with 2.2K EOL resistor
GROUND FAULT: A ground fault as tested by UL, is when an isolated ground terminal
of a Supervised zone labeled “G” is less than 0.1 Ohm impedance to Earth Ground. A
zone 10 Trouble is transmitted for this fault. The CID code generated at alarm automation
for a Ground Fault is E370 C010.
