Section 9. EXTERNAL SOUNDERS
Relay Output The Control provides a wet bell relay output which is used to power external alarm
sounders. Connections are made to terminals 4 (positive output) and 5 (negative
return). See SUMMARY OF CONNECTIONS Diagram.
UL Household Installations For installations which must provide UL Listed protection, the total current drawn
from this output and the auxiliary power output, combined, must not exceed
750mA in order to comply with the battery independence requirements. If two
System Sensor PA400 piezo alarm sounders, wired in parallel, are used (24mA
total), then 726mA (750mA Ð 24mA) is available for auxiliary output use.
UL
This control complies with National Fire Protection Association
(NFPA) requirements for temporal pulse sounding of fire notification
appliances.
Non-UL Installations For non-UL installations, the total current drawn from this output can be up to 2.8
amps. A battery must be installed since current in excess of 750mA is supplied by
the battery. Up to two 702 sirens can be used, wired in series. Up to two 719
sirens can be used wired in parallel.
Important: Going beyond the above mentioned limits will overload the power
supply or may possibly trip the bell output circuit protector.
Compatible Sounders UL
Use only UL Listed sounding devices for UL installations.
