AES 7788 Series RF Subscriber Unit ─ Installation and Operation Manual
AES Corporation 6 40-7788, Rev 6, August 30, 2016
1.1 Description
The 7788F Subscriber Unit is an AES-IntelliNet RF Communicator, which is typically
used to link an alarm panel to an alarm monitoring central station. This series unit is UL
Listed and NFPA compliant for commercial fire alarm monitoring. This unit has 8 wired
inputs. All 8 inputs are of the end of line resistor (EOL) type. For those that need or
want the reversing voltage inputs, there is another model – 7744F that has four inputs of
the EOL type and four reversing voltage inputs.
1.2 Features
This section is included for those customers familiar with other AES IntelliNet UL
Subscriber products. Listed below are the new features incorporated into the unit.
Fail Secure Relay on board for Acknowledge Delay / Antenna Cut / Low Battery /
Charger Fail output. Formerly was a Fail Safe open collector output and only for
Antenna cut / Acknowledge Delay.
Separate power no longer required for the Zone Input Module as required on the
7750-F-4X4 and 7750-F-8.
AC Failure Random Reporting Delay. AC failure/restore messages are generated
when they exist continuously for 100 minutes. The actual transmission of the
generated message is delayed a random number of minutes between 0 and 60, but
can be set to a value by the user. The delay is set at the time the event is
generated. This setting has no effect on the time of detection of the failure. That
is hardcoded at 100 minutes.
Transceiver power PTC is added. It is installed in series with the power line to
the transceiver disconnecting power if the transceiver draws too much current.
Remote programming using software at the central station is disabled when
Trouble Packets are enabled. This can temporarily be enabled using a directly
attached programmer in the Programmer Jack. This is to comply with UL/NFPA
requirements. Trouble Packets are enabled when “Y” is the response to the
question “Fire/Fire Zones” in Zone Programming <Ctrl> + F3.
1.3 Easy Installation
The 7788F unit is housed in a rugged lockable steel box for long lasting protection and
easy installation. The alarm panel’s alarm outputs are connected to the 7788F Unit. A
supplied AES-IntelliNet tamper resistant 2.5 dB flexible antenna can be secured to the
subscriber enclosure in the provided hole, or use a remotely installed antenna, purchased
separately. Once powered and properly configured, the 7788F RF Subscriber self-enrolls
into the AES-IntelliNet wireless network, receives signals from the alarm panel and
transmits them via wireless mesh radio to the AES-IntelliNet central receiver.
1.4 Power Requirements
The steady state DC current draw is only 150mA (210mA with optional accessories).
The peak current draw of 1.2A (1.3A with optional accessories) for RF power output
levels of 2W, is only for a very short transmit duration of less than 1/3 second.
