Tone Switch Locations

NOTES:

• Switch Positions 1 and 2 in the OFF position to select isolated horn and strobe power inputs
• Switch Position 6 ON = HIGH dBA
• Switch Position 6 OFF = LOW dBA

Super Slide® Mounting Bracket
Allows the installer to pre-wire the system, test for system supervision, remove the signal head until occupancy, switch out signals without changing mounting brackets and has locking edge connector for snap-in-place installation.

Checkmate Instant Voltage Verification

It is often necessary to confirm the voltage drop along a line of devices. The access holes are provided in the back of the terminal block to allow the voltage to be measured directly without removing the device. Typically, this would be done at the end of the line to confirm design criteria. Most measurements will be taken using the S+ and S- locations although access is provided to other locations.

NOTE:
Care should be taken to not short the test probes.

To remove bezel, grip both sides of bezel and pull in a download and outward motion.

NOTES:

• Operating temperature: 32°to 120°F (0° to 49°C). The 177 Series is not listed for outdoor use. The sound output for the temporal 3-tone is rated lower since the time the horn is off is averaged into the sound output rating. While the horn is producing a tone in the temporal 3 mode its sound pressure is the same as the continuous mode.
• For nominal and peak current across UL-regulated voltage range for filtered DC power and unfiltered (FWR [Full Wave Rectified]) power, see the installation manual.

Operating the horn in this mode at this voltage will result in not meeting the minimum ANSI/UL 464 reverberant sound level required for public mode fire protection service. These settings are acceptable only for private-mode fire alarm use. Use the high dBA setting for public mode application (not applicable when using the chime tone. The chime tone is always private mode).

RMS current ratings are per UL average RMS method. UL max current rating is the maximum RMS current within the listed voltage range (16- 33VDC for 24VDC units). For strobes, the UL max current is usually at the minimum listed voltage (16VDC for 24VDC units). For audibles, the max current is usually at the maximum listed voltage. For unfiltered FWR ratings, see the installation manual.

Architect & Engineering Specifications

The audible and/or visible signal shall be Potter S24-177 strobe and Potter HS24-177 horn/strobe Series or approved equal and shall be listed by Underwriters Laboratories, Inc. per ANSI/UL 1971 and/or ANSI/UL 464. The notification appliance shall also be listed with the California State Fire Marshal (CSFM).

The notification appliance (combination audible/visible) shall produce a peak sound output of 100dBA or greater at 24VDC as measured in an anechoic chamber. The signaling appliance shall also have the capability to silence the audible signal while leaving the visible signal energized with the use of a single pair of power wires. Additionally, the user shall be able to select either continuous or temporal tone output with the temporal signal having the ability to be synchronized. Unit shall be capable of being installed so that any unauthorized attempt to change the candela setting will result in a trouble signal at the fire alarm control panel.

The audible/visible and visible signaling appliance shall also maintain a minimum flash rate of 1Hz or up to 2Hz regardless of power input voltage.VThe appliance shall be polarized to allow for electrical supervision of the system wiring. The unit shall be provided with a mounting bracket with terminals and barriers for input/output wiring and be able to mount to a single gang or double gang box or double workbox without the use of an adapter plate. The unit shall have an input voltage range of 16-33 volts with either direct current or full wave rectified power for 24VDC models. The appliance shall be capable of testing supervision without disconnecting wires, verify voltage without removing unit and be capable of mounting to a surface back box.
