Periodic Testing
SAFEPATH periodic testing, including the SAFEPATH panel, all notification equipment and all messages, including their audibility
and intelligibility, content and language, sequence, output channel, and priority assignment, must be conducted frequently, at least
twice each year, or more often as required by local, state and federal codes, regulations and laws, by qualified personnel to ensure
proper operation of all equipment. If the notification equipment is not working properly, immediately contact the installer and have
all/any problems corrected immediately. Malfunctioning units should be replaced immediately. Do not attempt to repair
malfunctioning units. Malfunctioning units should be returned for factory repair or replacement. In the event you cannot contact the
installer, contact the manufacturer.
To aid qualified personnel in performing necessary operational testing procedures, a script, listing all messages programmed in the
SAFEPATH panel, must be kept with the SAFEPATH panel.
WARNING: PROVIDE ALTERNATIVE SIGNALING MEANS DURING PERIODIC TESTING TO ASSURE ADEQUATE
PROTECTION OF PEOPLE AND PROPERTY. FAILURE TO PROVIDE ALTERNATIVE SIGNALING MAY
CAUSE PEOPLE TO NOT BE WARNED OF AN EMERGENCY CONDITION WHICH COULD RESULT IN
PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
In addition to testing required by relevant fire codes, regulations and laws, several hardware functions should also be tested. The
hardware functions that should be tested are as follows:
1.
The "short circuit" detection circuitry for any one or all of the eight contact inputs.
2.
The serial port receiver.
3. The
play contact for each of the four output channels on the digital voice module.
4.
The "open circuit" detection circuitry for any one or all of the eight contact inputs.
5.
The audio supervision circuitry for each of the four audio channels.
6.
The status contact.
These hardware functions may be tested as follows:
1.
Activate (short circuit) each contact input and verify that proper message plays.
2.
Transmit a serial port command to the SAFEPATH panel and check for a valid acknowledge response.
3.
Monitor the play contact for each channel to verify proper operation while alternately playing and not playing files on the output
channel.
4.
Disconnect (open) each contact input and verify that the proper trouble condition is indicated.
5.
Listen to each message and check for audibility of each message.
6.
Monitor the status contact while causing the SAFEPATH panel to alternate between trouble and normal states to verify proper
operation.
If the SAFEPATH panel fails to perform any of the above tests correctly, immediately replace the malfunctioning SAFEPATH
module(s) following the SAFEPATH Module Replacement Procedure given in the “Troubleshooting” section.
