AES 7788 Series RF Subscriber Unit — Initallation and Operation Manual 1.1 Description The 7788E Subscriber Unit is an AES - IntelliNet RF Communicator, which is typically used to Zink 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. L2 New 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. • Normally Open Relay on board for Acknowledge Delay / Antenna Cut / Low Battery / Charger Fail output. Formally was an open collector output and only for Antenna cut / Acknowledge Delay. Relay energized for normal condition, de- energized for any fault or loss of power. • 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 The delay is set at the time the event is generated. • Transceiver power PTC is added. It is installed in series with the power line to the transceiver disconnecting power if the transceiver draws to much current. • Remote programming using software at the central station is disabled when Trouble Packets are enabled. Trouble Packets are enabled by entering Y to "Fire Zones ? Y/N:" prompt in Zone Programming. This can temporarily be enabled using a directly attached programmer in the Programmer lack. 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 7788E 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 15OmA (21 OmA with optional 7067 IntelliTap or 7770 FireTap Modules). The peak current draw of 1.2A (1.3A with optional 7067 or 7770) for RF power output levels of 2W, is only for a very short transmit duration of less than 1/3 second. AES Corporation s 40 -7788.
