The SPMNS, which meets UL 2572 requirements for MNS, interfaces with a building fire alarm system (FAS) to provide a complete In-Building MNS. An integral part of the fire system, the SPMNS controls all audio and visual notification appliances for both fire and MNS and reports trouble and supervisory signal through the FAS. Supervised voice speakers controlled by the SPMNS can be used for both fire and emergency communication applications.
The SPMNS single channel system is capable of delivering 40 watts of supervised high fidelity audio power and 2 amps of supervised 24 VDC synchronized strobe power. It comes standard with an on-board digital voice messaging system with 8 standard messages, a hand-held microphone for fire messages, power supply/battery charger and numerous additional features. A dedicated MNS microphone (SPMNS-MIC) will be utilized for live voice messages for emergency communications. The SAFEPATH system is expandable to 5280 watts utilizing the SPB-80/4 (80 watts and 4 amps of strobe power), the SPB-160 (160 watts) or SPB-320 (320 watts) supervised audio power boosters.
