Bid No.041818-Installation of New Fire Alarm System at Adams Elementary School
1.
Provide to supervise and control operation of 1 conventional NAC of compatible, 24-VDC
powered, polarized audio/visual notification appliances or UL-listed polarized relays for fan
shutdown and other auxiliary control functions.
2.
Mount in standard 4-inch (101.6-mm) square, 2-1/8-inch (54-mm) deep electrical box or to
surface-mounted back box.
3.
Control Module NAC: Wire for Style Z or Style Y (Class A/B) with up to 1 amp of inductive
signal or 2 amps of resistive signal operation. Relay coil shall be magnetically latched to
reduce wiring connection requirements and to ensure 100 percent of all auxiliary relay or
NACs shall be energized at same time on same pair of wires.
4.
Audio/Visual Power: Provide by separate supervised power circuit from main fire alarm
control panel or from supervised, UL-listed remote power supply.
P.
Addressable Control Modules (MMO-6SF):
1.
Provide to supervise and control operation of 1 conventional NAC of compatible, 24-VDC
powered, polarized audio/visual notification appliances or UL-listed polarized relays for fan
shutdown and other auxiliary control functions.
2.
Mount in factory-supplied MBB-2 or MBB-6 enclosure.
3.
LEDs: Flash under normal conditions, indicating monitor module is operational and in
regular communication with control panel.
4.
Control module NAC: Wire for Style Z or Style Y (Class A/B) with up to 1 amp of inductive
signal or 2 amps of resistive signal operation. Relay coil shall be magnetically latched to
reduce wiring connection requirements and to ensure 100 percent of all auxiliary relay or
NACs shall be energized at same time on same pair of wires.
5.
Audio/Visual Power: Provide by separate supervised power circuit from main fire alarm
control panel or from supervised, UL-listed remote power supply.
Q.
Addressable Relay Modules (AOM-2RF):
1.
Available for HVAC control and other building functions. Relay shall have 2 Form C sets
of contacts that operate in tandem and are rated for a minimum of 2.0 amps resistive or
1.0 amps inductive. Relay coil shall be magnetically latched to reduce wiring connection
requirements and to ensure 100 percent of all auxiliary relay or NACs shall be energized
at same time on same pair of wires.
2.
Mount in standard 4-inch (101.6-mm) square, 2-1/8-inch (54-mm) deep electrical box or to
surface-mounted back box.
R.
Addressable Relay Modules (MMO-6RF):
1.
Available for HVAC control and other building functions. Relay shall be Form C and rated
for a minimum of 2.0 amps resistive or 1.0 amps inductive. Relay coil shall be
magnetically latched to reduce wiring connection requirements and to ensure 100 percent
of all auxiliary relay or NACs shall be energized at same time on same pair of wires.
2.
Mount in factory-supplied MBB-2 or MBB-6 enclosure.
3.
LEDs: Flash under normal conditions, indicating monitor module is operational and in
regular communication with control panel.
