Ademco - 7720 Subscriber Radio

DEIVICOJ RADIO 7720 self contained subscriber radio is the subscriber end of a long Range alarm reporting system As a communications by analogy to a system the 7720 is comparable to a digital communicator by telephone line to a central monitoring station Note to the Installer Please read these Installation Instructions all way through and become completely familiar with them before to install a 7720 subscriber radio l 92 3 3 I FEATUFiESm I e 2 BAllERY SHmDOWN NDCATlONS s FAULT LED PATTERNS 3 THE JUMPER OKlO 4 THE nxrs tmUNTlNG 8 PcwJERING 5 A772OP QUESTIONS 6 PROGRAM MODE 9 FEATURES alarm and messages are transmitted the station network via radio signals means and more secure entire link equipment supply battery and is housed in a single unit requiring battery charging power and alarm from a standard 12 volt alarm panel can monitor alarm ACP Ademco ECP discrete 4 contact closures or their electrical or from external gate and inputs 7720 is compatible existing installations using ADEMCO or other control panels The can be used in conjunction with communicators one both acting as backup use an ADEMCO 659 EN connected to a zone input to report line cut and backup a digital dialer while the radio fault output to a zone the dialer normal operation protection built in cover will trigger an alarm whenever the cover is removed thus protecting unauthorized access to the 7720 tamper zone number must be entered programming question 25 to enable LEDs battery conditions and blinking yellow LED I I 10 A SflE FAST MODE 10 WIRE ANTENNA mm 10 CONNECTOR KIT m w 11 I 1 CohrMAND 11 7720 f OR UL INSTALLATIONS 12 12 DIAGRAM 13 7720 Erasable 7720 comes an omni directional wire antenna and an optional antenna kit for using a 7625 antenna EEROM technology which allows the 7720 to programmed with a 7720P Programming The programming options assignments for Telco fault input trigger inputs delayed 16 second delay selected of the transmitter fault low output power loss of power low internal DC voltage and radio frequency circuit problems be reported on both ACP ECP as well as being transmitted to master station network the fault not predude such transmission For can alarm panels closures on a Form to Supply The 7720 is powered by own 12 volt battery which can be by an alarm panel output voltage The charging input draws peak current during transmission Battery Monitoring notify condition whenever drops below 11.2V 5 Battery volts radio will automatically Refer to the LOW BATTERY section for more information system central station of a low battery for any battery voltage drops below continuous faults 7720 will 16 seconds alarm or other activate on 4.512VDC The 7720 receives alarm and signals alarm control and converts these signals to radio the which are transmitted station network which turn the messages to the central station 7720 can monitor either 4 traditional inputs or can process serial data panels which use either ACP or ECP formats For traditional zone inputs first two zones may be configured by activate on either 0 volts or on 4.512VDC zones 3 and 4 are 1 4 can also be programmed their input signals receiving an alarm restore or status the master station network a programmed delay of either 250 will repeat for approximately minutes total of 60 messages to ensure will be by the central monitoring station 7720 transmits periodic supervisory central station problems A contact closure to indicate a radio fault this can either normally open or normally closed addition can be selected to be by programming the fault output to be i e the relay is powered unless is a fault The fault output is between and TBl 2 which float with reference the rest of the circuit n20 also provides status information its serial port to be displayed on command using a 7720P Programming Tool or a terminal Refer to the TESTING 7720 section for information regarding command and status messages can use either the wire antenna or by using 7720ANT connector kit can use a omnidirectional 7625 3dB if additional gain is required a or 7674 13 YAGI antenna The antenna mounts directly the The other antennas can be mounted if desired using preassembled cable available from ADEMCO 5 or 25 lengths allowing alert voltage drops below 9.75 volts the will automatically shutdown and ALL battery WILL BE OFF When to 10.25 volts LEDs will to flash in rapid unison see LED until the battery is charged to 12.5 During The 7720 will resume normal after the battery is fully charged Flash Solid Solid Y EL solid Message YEL Rashing HS test cylcle ON Flash Test or FAST message O second Flash Isecond Flash Normal but low ban or DC per 3 set charging condition detectec operallon Fault detected Flash Patterns Table Power On Reset sequence twice before normal mode
