Alert Alarm III
4
5.2 Power Out
The Power Out alarm can occur in two cases. One is when the power has been out for more that one
minute. The other situation could be caused by the 120VAC 2 amp fuse located at the bottom, back
of the box, being blown. If the power out alarm condition is active, and you find that there is power
present at the outlet where the alarm is plugged in, then you should check the fuses. Note that both
fuses are 2 amp.
5.3 No Siren at Test
If the siren fails to sound when the test button is pressed, several scenarios could be present. First,
the battery fuse could be blown. Note that both fuses at the bottom of the box are 2 amp. Secondly,
the battery could be disconnected or depleted. Third, the siren itself could be bad. Check for
12VDC at the siren leads themselves. And, of course, there could be a bad connection somewhere
in the siren circuit.
5.4 Temperature Sensors Out of Calibration
If the operator feels that the temperature sensors are not correct, he should follow these steps:
Remove the Upper and/or Lower limit setpoint knobs by loosening their set screws. Next, turn the
Lower limit shaft counter clockwise until it stops. Now, turn the Upper limit shaft clockwise until it
stops--there should be no sensor lights lit. Next, turn the Upper limit shaft until the sensor indicators
are lighted--at this point, you should replace the Upper limit knob with the white indicator arrow
pointing to the correct temperature and tighten it down. Follow the same steps to set the Lower limit
setpoint.
5.5 Trouble-Shooting the Auxiliaries
The auxiliary inputs must always form a closed loop. If the loop is ever open, the alarm will sound.
If an auxiliary input is sounding, the trouble can be isolated between the alarm and the circuit by
disconnecting the circuit from the terminal block in the alarm box and replacing it with a jumper. If
the corresponding auxiliary input still causes an alarm condition, the problem is the alarm, otherwise
the circuit is the culprit.
6. Installation
6.1 Mount the Box
The box should be mounted in a location where it will be protected from damage. The enclosure is
waterproof and should be mounted using the mounting kit supplied with the controller. Holes drilled
through the box allow a path for moisture, dust, and ammonia and will void your warranty.
6.2 Installing Sensors
After determining the location of the sensors, they should be attached to the walls, and/or ceiling of
the confinement building. Next, run the two wires into the enclosure via the watertight connector at
the bottom of the box. The wires should be cut off and a spade terminal crimped to their ends. They
next should be attached to the terminal block in the positions marked Sen 1 and Sen 2. Note that the
sensors are not polarity sensitive, and it therefore makes no difference as to which wire goes to
which sensor terminal.
6.3 Attaching the Siren
After the siren is mounted, it should be wired into the control box. This is done at the terminal
block locations labeled
siren red
and
siren white
. Note that polarity is important here and that the
red siren wire must be connected into the
siren red
terminal block position and the same for the
white wire. Note also, any 12VDC device which uses less that 1 amp of current could be connected
in the siren’s place.
