These smoke detectors are UL Listed for use with the FOCUS 200 PLUS, and are the
only
2-wire smoke
detectors that may be used.
Figure 4-1: 2-Wire Smoke Detector Connected to Point 1 (can also be connected to Point 2,
Terminals 27 and 28)
To wire 2-wire smoke detectors to points 1 and 2 (terminals 25 - 28), perform the following steps:
Step Action
1 Select from the list compatible 2-wire smoke detectors.
Note:
These are the only 2-wire smoke detectors that may be used with the FOCUS 200
PLUS system.
2 Connect 2-wire smoke detectors across point 1 and/or point 2 terminals (25 through 28).
See
Figure 4-1.
Note:
Observe proper polarity when connecting the detectors.
3 If EOL resistors are presently connected across point 1 and point 2 terminals, remove
them. Connect the EOL resistors across the loop wires of each point at the last detector.
Wiring 4-Wire Smoke Detectors to Points 1-8
When programmed for fire, points 1-8 can monitor 4-wire smoke detectors, normally-open fire alarm
initiating devices, or normally-open sprinkler system supervisory devices.
You may use as many 4-wire smoke detectors as can be powered from the panel's Auxiliary Relay
Output without exceeding the output's rating. Program the Auxiliary Relay Output to respond to 4-wire
smoke detector reset. Also, Jumper P3 must be set to the top position, shorting pins 1 and 2.
U
L
Power to 4-wire smoke detectors must be supervised with an EOL device (use a ADT 435243 or a System
Sensor A77-716B EOL Relay Module). See
Figure 4-2.
Auxiliary power to 4-wire smoke detectors is not automatically reset after an alarm, and therefore must be
momentarily interrupted using the built-in auxiliary relay. This allows the detectors to be reset via the Alarm
Reset sequence.
Programming for the Alarm Reset sequence must be done via the downline loader in order for the system
to process the command properly.
Compatible 4-Wire Smoke Detectors
Use any UL Listed 4-wire smoke detector that is rated for 10-14VDC operation and that has alarm
reset time not exceeding 6 seconds. Some compatible 4-wire smoke detectors are listed below.
