The PS-110 is designed to provide convenient reliable service. This compact, easy-to-use monitor plugs into any
standard 2-prong 120V AC outlet that requires monitoring. It has an attached 15’ (4.57 m) cable that wires into
remote warning devices such as alarm systems, telephone dialers or other emergency equipment.
When power to the monitored circuit is interrupted for more than 3½ to 8 consecutive minutes, the PS-110
activates alarms and dialers through a dry contact output. This time delay feature means that short power
outages (< 3½ minutes duration) will not cause the PS-110 to activate. As long as electrical power is restored
within 3½ minutes to the circuit which the PS-110 is monitoring, the unit will automatically reset itself to a
normal condition. Several PS-110s can be wired into a single warning system, making power failure monitoring
for an entire complex easy.

INSTALLATION
A standard screwdriver is all you need to install PS-110.
STEP 1
Disconnect AC Power
To prevent possible injury, shut off electrical power to the circuit by turning off the circuit breaker or removing the
circuit fuse.
STEP 2
Mounting
Plug the PS-110 into a working 2-prong 120V electrical outlet (this outlet should not be controlled by a wall switch).
Remove screw from the center of the outlet’s faceplate and attach the PS-110 with the eyelet and screw.
Note: DO NOT use an extension cord to increase the distance between the electrical outlet and the sensor.
STEP 3
Connecting Power-Out Alert
Connect sensor wires to the remote device being used to receive the warning signal from the PS-110.
STEP 4
Restore power to circuit
Restore electrical power to the circuit by turning the circuit breaker back on or by replacing the fuse. Wait
approximately 15 minutes for the sensor to become operational before continuing. (The time delay will vary
depending on the ambient room temperature.)
STEP 5
Testing
Manually activate the sensor for testing by interrupting the electrical power to the circuit by turning off the circuit
breaker or by removing the fuse for 3½ to 8 minutes. Within 3½ to 8 minutes of the loss of power, the PS-110 will
activate your remote device.
Note: Remember to disconnect the telephone line during testing if the PS-110 is connected to a security system
which incorporates a telephone dialer. Following this procedure will eliminate the possibility of a false alarm
whenever the unit is tested. When testing is complete, remember to reconnect the telephone line if the PS-110 is
connected to a security system which incorporates a telephone dialer.
To insure proper operation, test unit weekly.

FREQUENTLY ASKED QUESTIONS
Is the 3 1/2 to 8 minute response time adjustable?
No, the response time is determined by the ambient room temperature.
Warmer temperatures = slower response for alarms.
Colder temperatures = slower response for clearing alarms.
Is the Power-Out Alert normally closed (N.C.)?
No. The PS-110 operates in normally open (N.O.) mode and closes upon alarm condition.
