Walk through test system
First Claim
1. Method of testing devices distributed throughout one or more zone loops remote from a central panel, comprising:
- monitoring said devices in a test mode for an alarm condition,placing at least one of said devices in an alarm condition,detecting the alarm condition at the central panel and automatically sounding an audible on/off code which is aurally detectable at the location of the device placed in said alarm condition,said audible on/off code identifying the zone loop in which the device placed in said alarm condition is connected.

Abstract
Walk through test system for testing devices such as pull stations, smoke detectors, alarm bells and the like for alarm and trouble conditions without the assistance of a central panel operator. The devices are connected in a loop or loops distributed throughout one or more zones remote from a central panel. Alarm and trouble conditions are detected at the central panel. When a device is placed in alarm by the workman, a coded alarm is sounded which is aurally detectable by the workman at the location of the device, remote from the central panel. The coded alarm identifies the zone loop in which the device is connected. When a trouble condition is created in a loop by the workman, an alarm is sounded which is aurally detectable at the location of the loop, remote from the central panel. The alarm is coded to indicate to the workman that a trouble condition has been detected at the central panel. A device which has been placed in alarm is automatically reset by the central panel after the coded alarm has been sounded, so that the next device can be tested.

1. Method of testing devices distributed throughout one or more zone loops remote from a central panel, comprising:
-
monitoring said devices in a test mode for an alarm condition, placing at least one of said devices in an alarm condition, detecting the alarm condition at the central panel and automatically sounding an audible on/off code which is aurally detectable at the location of the device placed in said alarm condition, said audible on/off code identifying the zone loop in which the device placed in said alarm condition is connected. - View Dependent Claims (3)

2. Method of testing devices distributed throughout one or more zone loops remote from a central panel, comprising:
-
monitoring said devices in a test mode for an alarm condition and a trouble condition, placing at least one of said devices in an alarm condition, detecting the alarm condition at the central panel and automatically sounding an audible on/off code which is aurally detectable at the location of the device placed in said alarm condition, said audible on/off code identifying the zone loop in which the device placed in said alarm condition is connected, creating a trouble condition in a zone loop, and detecting the trouble condition at the central panel and automatically sounding an audible alarm which is aurally detectable at the location of said last mentioned zone loop.

4. Apparatus for testing devices distributed throughout one or more zone loops remote from a central panel, comprising:
-
means at the central panel for monitoring each of said devices in a test mode for an alarm condition, sounding means for sounding an alarm which is aurally detectable at the location of each of said zone loops, and means at the central panel for detecting a device in an alarm condition and for automatically causing said sounding means to sound an alarm which is coded so as to identify the zone loop in which said device in said alarm condition is connected. - View Dependent Claims (6, 7)

5. Apparatus for testing devices distributed throughout one or more zone loops remote from a central panel, comprising:
-
means at the central panel for monitoring each of said devices in a test mode for an alarm condition, sounding means for sounding an alarm which is aurally detectable at the location of each of said zone loops, means at the central panel for detecting a device in an alarm condition and for automatically causing said sounding means to sound an alarm which is coded so as to identify the zone loop in which said device in said alarm condition is connected, and means at the central panel for detecting a trouble condition in a zone loop and for automatically causing said sounding means to sound an alarm which is coded to indicate detection of a trouble condition. - View Dependent Claims (8, 9)
