AES 7788 Series RF Subscriber Unit ─ Installation and Operation Manual
AES Corporation 19 40-7788, Rev 6, August 30, 2016
J1 – RS-232 Port for Programmer and External Module connection. Plug
programmer’s cable into this jack to perform programming functions.
Programmer is powered by the power supply of the Subscriber. The AES
IntelliTap, FireTap or other supported accessory modules are connected and
powered by this jack. Any attached module must be disconnected to connect
the programmer and the programmer must be disconnected to use a module. 12
VDC 250 mA maximum, Unsupervised
J2 – Zone wiring to this terminal block. Zone wiring examples are in
Section 3.4. Terminals are not suitable for multiple wires. Use wire Nut and
pigtail to connect more than one wire to a single terminal labeled G. Supervised
J4 – (Trbl) – Antenna Cut / Trouble output Local. This is for local reporting
or annunciating of antenna cut, communication troubles, low battery or charger
fault. See Section 3.5 for details. Unsupervised. 24 VDC, 1-Ampere resistive
maximum.
J5 – Battery Input. Attach 12 VDC battery to the Red and Black ▬ battery
wires carefully observing polarity. An onboard self-resetting fuse protects
Battery wiring. For separation of circuits, battery wires are covered with Teflon
tubing. Supervised, Max current 1 Amp
J6 – Power Input. Connect approved VAC power to this terminal block.
Refer to Section 4.3 for information on detection and reporting delays.
Supervised.
Earth Ground. Earth Ground and Battery minus (-) are not separated
connections in the AES IntelliNet 7788F Subscriber. Zone Input terminals
including the “G” Terminals on J2 Zone input block are isolated from Earth
Ground.
Using 18 gauge wire minimum (10 Ga. Min suggested), attach a suitable Earth
Ground to the #6 threaded standoff identified with a green lock-nut on the
inside of the enclosure. A superior method for connecting Earth Ground to the
Subscriber is to bond directly to the bare sheet metal of the enclosure.
Suitable Earth Grounds include building steel, buried metallic cold water pipe,
driven grounding rod and other grounding systems. Not suitable is the
electrical ground from the electrical panel.
3.5 Wiring – Antenna Cut / Trouble Output (J4)
Antenna Cut / Ack Delay / Low Battery / Charger Fail Output
J4 is the output connector for the Form C Fail Secure Antenna Cut / Acknowledge
Delay Relay / Low Battery / Charger Fail located on the 7788F circuit board. The
7788F will engage this relay for normal operation. It will be disengaged for one or
more of the following reasons: 1) Reset, (remote or local) 2) non-powered
condition, 3) Acknowledge Delay which will occur after an antenna cut or loss of
communication with the network. An Acknowledge delay occurs when a Packet
Acknowledge is not received for a transmitted Data Packet within the programmed
Acknowledge Delay time. (Default Ack Delay Time is 60 seconds). 4) Low Battery
or Charger Fail. Must be attached to an FACP or a local annunciation device.
