Specifications
The system shall be a multi-purpose NFPA compliant, supervised, re/emergency communications system and shall interface with a building re alarm system
(FAS) to provide a complete In-Building MNS. The system shall control all audio and visual notication appliances for both re and MNS and report trouble and
supervisory signal through the FAS. The system shall be capable of delivering 40 watts of supervised audio power and 2 amps of supervised 24 VDC synchronized
strobe power. Minimum supervised audio power shall be 40 watts, expandable to 5280 watts, depending on system conguration and with additional modules
and power boosters. Supervised 24 VDC synchronized strobe power shall be 2 amps, expandable to the requirements of the installation. The system shall be
capable of operating from a 120 VAC power source. SPMNS shall be capable of operating from a 240 VAC power source. All models shall have a 24 VDC
battery backup. Standard on-board system features shall include: digital voice messaging, a hand-held push-to-talk microphone with override priority, and a power
supply/battery charger. Form C contacts shall be provided for system alarm and trouble conditions.
The system shall have 8 message contacts with contact closure activation. The system shall have 10 priority ordered inputs, including: On Board Microphone,
Auxiliary Input (Line Level), and 8 Digital Messages. The system shall have preset audio levels for emergency messaging (prerecorded and live mic). The
system shall be supplied with 8 pre-recorded messages and be capable of in-eld recording of customer unique messages. The system shall have a dual-tone
tone generator with Code-3 Tone and Slow Whoop.
The panel shall have power-limited circuitry with an internal battery charger and power supply. The power supply/charger section shall be able to charge 24 VDC
batteries with a maximum capacity of 33 amp hours. Up to two 12 VDC, 12 AH batteries may be housed in the enclosure. Batteries larger than 12 Ah shall be
housed in a separate enclosure such as the Cooper Wheelock BATC or equivalent. Batteries shall be supplied separately.
The system shall have power limited circuitry and class B wiring. Wiring terminal blocks will be removable and accept #22 - #12 AWG wire. Audio output voltage
shall be selectable for 25V or 70.7V. The voice (live microphone or recorded message) frequency response shall be 275 Hz – 6.5 kHz. Stand by current draw
shall be 140mA. Alarm current draw shall be 4.7 amps. The signal to noise ratio shall be better than 65 dB, dynamic range shall be better than 65 dB, total
harmonic distortion shall be less than 2%.
The system shall be wall mountable, enclosed in a steel locking enclosure. The required batteries for 40-watt systems shall t inside the enclosure. The 40 watt
system shall weigh no more than 36 lbs (without batteries) and its dimensions shall not exceed 21” H x 16” W x 6” D. Approvals for the system shall include: UL
Standard 864, 9th edition, UL 2572 for MNS, and UL Standard 1711. The system shall be OSHA 1910.165, and ADA compliant. 1 Year Warranty.

Mass Notication System
11
The power supply shall be Wheelock POWERPATH™ Series PS-8, or equivalent. The unit shall be stand alone power supply intended for powering re alarm
notication appliances via its own Notication Appliance Circuit(s) (NAC). The unit shall be UL 2572 for MNS, UL 864 Listed for power limited operation of outputs
and comply with NFPA 70 (NEC), article 760.
The power supply shall support a full 8A of notication power even if the battery is in a degraded mode and only AC power is connected.
The power supply shall be activated by a standard Notication Appliance Circuit (NAC) from any Fire Alarm Control Panel (FACP) or a “Dry contact” opening.
The units shall be 8 ampere, 24 VDC, regulated and ltered, supervised remote power supply/charger. It shall operate over the voltage range of 8 to 33 VDC
or FWR. The primary application of the unit shall be able to expand re alarm system capabilities for additional NAC circuits to support ADA requirements and
to provide auxiliary power to support system accessories or functions. The power supply shall provide four Class “B”, two Class “A”, or two Class “B” and one
Class “A” NAC circuit(s). Eight Class “B” or Four Class “A” circuits shall be available with an optional PS-EXP module. The PS-8 unit shall supply up to 240 mA
of auxiliary power that is available during both non-alarm and alarm or auxiliary power of not less than 2.5A at 24 VDC during non-alarm. The power supply shall
be capable of charging batteries of up to 33 ampere hours per NFPA 72 at maximum rate of 0.750 Amps per hour.
Input activation options shall be from not less than two NAC circuits or Dry Contact closures. These inputs shall have the capability of being directed to any
combination of the four NAC circuit outputs. Each NAC circuit output shall be rated at 3 amperes for Class “B” applications or 3 amperes each for Class “A”. The
outputs shall be programmable to generate a steady or Temporal (Code 3) output and or a synchronized strobe or horn output. The power supply shall provide
independent loop supervision for either Class “A” or Class “B” FACP NAC circuits and shall have the capability to “steer” all alarm or trouble conditions to either
incoming NAC circuit. The units shall have common trouble terminals. The power supply shall be powered from a 120 VAC source with a current consumption of
xx amperes max. The unit shall incorporate short circuit protection with auto reset. The power supply shall incorporate a built in battery charger for lead acid or
gel type batteries with automatic switchover to battery back up in the event of AC power failure. The charger shall incorporate fused protection for the batteries
and have the ability to report low battery and/or no battery condition(s). Standby current for battery back up shall be 0.129 Amps max. The power supply shall
have the ability to latch trouble LED’s so the circuit in trouble can be identied. The cabinet dimensions shall be 17” H x 15” W x 5.5” D.
