to activate the bell. It also provides a Form “C” Bell
Fault Output to be connected to the control panel.
• Current Draw = 7 mA @ 12 VDC, Standby. 50 mA @
12 VDC, Alarm.
• DS7481: Single Phone Line Monitor (1 per system).
The DS7481 provides a means of monitoring a single
phone line for fault conditions. When a fault is detected,
the DS7481 automatically closes its Normally Open
relay contacts to provide a means of signaling the fault.
• Current Draw = 20 mA, Standby. 20 mA, Alarm.
• DS7488: Octal Relay Module (2 per system).
The DS7488 provides 8 Form “C” relay outputs for
addition to the system. The outputs are fully
programmable and can be activated by system events.
Each output operates individually of the other 7 outputs
for complete flexibility.
• Current Draw = 10 mA + 40 mA for each relay when
energized.
• DS7489: Solid State Output Module (2 per system).
The DS7489 is a Solid State Octal Driver Module that
provides 8 open collector transistor outputs. The
outputs are fully programmable and can be activated
by system events. Each output operates individually
of the other 7 outputs for complete flexibility. The
DS7489 Module has not been investigated by
Underwriters Laboratories, Inc.
• Current Draw: 10mA.
• Outputs: Provides a current sink (the output shorts
to common (-) when activated). The maximum current
draw for all 8 outputs combined cannot exceed 750
mA.
• MX280: Multiplexed Photoelectric Smoke Detector (up to 120
detectors may be used per system. Requires a DS7430
and occupies one multiplex zone). Detects smoke and
automatically determines the detector’s sensitivity
using the Detection Systems “Chamber Check” feature.
The MX280 Detector has not been investigated by
Underwriters Laboratories, Inc.
• Current Draw: 500 µA Standby, 560 µA Alarm.
• MX280TH: Multiplexed Photoelectric Smoke Detector with a 135°F
(57° C) heat sensor (up to 120 detectors may be used
per system. Requires a DS7430 and occupies one
multiplex zone). Detects smoke and is equiped with a
135°F (57° C) heat sensor for high temperature alarms.
The Detection Systems “Chamber Check” feature
automatically determines the detector’s sensitivity. The
MX280TH Detector has not been investigated by
Underwriters Laboratories, Inc.
• Current Draw: 500 µA Standby, 560 µA Alarm.
• MX280THL: Multiplexed Photoelectric Smoke Detector with a
135°F (57° C) heat sensor and a 45°F (7° C) freeze
alarm (up to 60 detectors may be used per system.
Requires a DS7430 and occupies two multiplex
zones). Detects smoke and is equiped with a 135°F
(57° C) heat sensor for high temperature alarms and
a 45°F (7° C) sensor for freeze alarms. Freeze alarms
are reported separately from smoke and high
temperature alarms. The Detection Systems “Chamber
Check” feature automatically determines the detector’s
sensitivity. The MX280THL Detector has not been
investigated by Underwriters Laboratories, Inc.
• Current Draw: 500 µA Standby, 560 µA Alarm.
• MX540: Multiplexed Passive Infrared (PIR) Intrusion Detector
(DS7473) with a standard range of 40 by 50 feet (12 by 15
meters). Requires a DS7430 and occupies one
multiplex zone.
• Current Draw = 800 µA Standby and Alarm.
• MX835: TriTech Microwave/PIR Intrusion Detector with “Pet
Avoidance” technology and a standard range of 35 by
35 feet (10.7 by 10.7 m). Requires a DS7430 and
occupies one multiplex zone.
• Current Draw= 6 mA standby, 35 mA in “Trouble”
and walk test mode.
• MX775 Multiplex Passive Infrared (PIR) Intrusion Detector with
(DS7470) a standard range of 50 by 50 feet (15m by 15m).
Requires a DS7430 and occupies one multiplex zone.
• Current Draw= 200 µA standby, 2 µA in walk test
mode.
• MX794 The MX794 is a Long Range Multiplex PIR Intrusion
(DS7474) Detector with Self-test. The standard ranges are 80 ft.
by 50 ft. (24.0m by 15.0m) and 200 ft. by 10 ft. (61.0 m
by 3.1 m). Requires a DS7430 and occupies one
multiplex zone.
• Current Draw = 800 µA Standby and Alarm.
• MX934 Multiplex Passive Infrared (PIR) intrusion detector with
(DS7471) a standard range of 35 by 35 feet (10.7m by 10.7m).
Requires a DS7430 and occupies one multiplex zone.
• Current Draw= 200 µA standby, 2 µA in walk test
mode.
• MX938 360° Ceiling Mount Multiplex PIR Intrusion Detector
(DS7472) with a 60 foot (18.3m) diameter range. Requires a
DS7430 and occupies one multiplex zone.
• Current Draw= 200 µA standby, 2.5 µA in walk test
mode.
• MX950 Multiplex TriTech Microwave/PIR Intrusion Detector
(DS7476) with motion monitor and anti-mask features and with
