nected and that the battery fuse (in line with the red wire con- nected to the battery in the Model 1503 Control/Communicator) is good. The BATTERY LOW indica- tion will remain until the next battery test is run, 1 hour later, or when a SHOW TEST com- mand is given.

- COMMUNICATOR TRBL NOW: Indi- cated if the digital communica- tor (not the voice dialer) was unable to make contact with the Central Station after trying both numbers multiple times. This indication will remain un- til the digital communicator tries again (as a result of a reportable alarm or event occur- ring) or until both phone num- bers are removed from the digi- tal communicator. If this hap- pens, there could be a problem with the system, central sta- tion, phone line or the wrong phone numbers have been entered in the digital communicator. Call your dealer for service.

-DEVICE FUSE TRBL NOW or HAD TRBL: Indicated if there is a problem with one (or more) of three solid state fuses on the Model 1503 Processor Module.

These fuses can be restored without having to replace anything. They can be seen by opening the Model 1503 Control/Communicator enclosure door and looking in the opening of the aluminum cover on the door. At the bottom you will see three small round components labeled PTC1, PTC2 and PTC3.

Model 1503 Owner's Manual

The three fuses are for (from left to right) the CONSOLES, the DEVICES and the HORNS.The CONSOLES are powered through the fuse la- beled CONSOLES. If the CONSOLES fuse is “blown”, then the consoles will not be working. The DEVICES fuse powers the following devices that may be connected to the system (some are options:)

-motion detectors

-smoke/fire detectors

-AUXiliary OUTputs (energy saver relays)

-COMMUNICATOR outputs

-OK TO ARM output

-ARMED output

The HORNS fuse powers the Inte-

rior siren and the Outdoor Siren. If it is hot, there is a fault in the wiring to one of these devices.

To reset these fuses, the fault must be cleared. Then, unplug the Model 1503 power transformer (or remove the tube type fuse on the Termination Board.) Disconnect, then immediately reconnect the battery (within 10 seconds to re- tain your home control programs.) Wait a minute or two for the PTC fuse to cool. Then plug in the transformer. If you do not feel competent performing such tasks, call your dealer for service.

NOTE: If the battery is discon- nected or the battery fuse is blown you will get a DEVICE FUSE TROUBLE indication AND a BATTERY LOW indi- cation when the battery test oc- curs.

-PHONE LINE DEAD TRBL NOW or HAD TRBL will be indicated if the phone line is dead for more than 1 minute. If this happens, check
