QUESTION ANSWER

1 "I have a UTA-1 in a washdown area. Is it ok if I

hose it down?"

Although the unit is weather resistant, it is not

recommended to directly spray the unit with water.

2 "I purchased, the CRT-T-40 Relay. After the

phone rings the relay contacts seem to stay

closed."

First check to see if you have the relay set to the low

sensitivity. If this does not fix the problem gently bend the

contacts up.

3 "My customer is calling me looking for a loud

horn for his garage. He currently has an old

Wheelock bell on the wall but I can’t seem to find

it in your catalog. What would be the

lacement?"

The bell you are referring to is probably a Series 163

Bell.The recommended replacement would be a

MTH-24, which is 117dB, and a CRT-T-40 which is the

relay to activate the horn.

4 "I am trying to get the UTA-WH-VPS to operate on

my analog phone no matter what phone I try the

thing won’t ring. What is the issue?"

That unit requires a 115vac wired directly to TB3 on the

unit.

5 "My customer has called me to fix his

PS-33A-WPW because it won’t stop flashing on

his analog phone line. Do you have any

suggestions?"

The unit is working fine. The problem is the unit is not the

right product for the application. That device requires 18-

30 volts AC or DC. The device you need is either the PS-

11A-WPW, which also needs to be plugged into a 110

VAC wall outlet, or the PS-15A-WPW, which can connect

directly to the analog phone line.

6 "I have a CA-312 that was working but I moved its

location and now it does not operate even though

I measure ring voltage coming into device."

The common problem with these devices is they require a

good ground. If you place your butset on tip and the

ground you are using and do not pull dial tone, it will verify

that the ground is not correct. Make sure you have a solid

earth ground.
