3 Overview SIP-H-1/-5 Hazardous Area Page/Talk Wall Stations Guardian's Page/Talk Systems provide reliable and easy to use paging and communication within industrial environments such as plants, mills and factories. Individuals can be paged from any station and two or more persons can communicate on any available line. The Models SIP-H-1 (Single-line) and SIP-H-5 (Multi-line) stations described in this manual are designed for use in Class I, Division 2 hazardous locations. Each SIP-H-1/-5 Wall Station provides up to twelve watts of paging power for an external loudspeaker. A press bar on the handset enables one-hand paging operation. In order to avoid acoustical feedback from a loudspeaker receiving a signal from the station, a jumper on the circuit board provides for the speaker to be muted when the Page button on the handset is pressed. Group muting is also available for the same purpose, this feature mutes adjoining speakers when the page button on any station in the group is pressed. Guardian's stations and related equipment are compatible with systems provided by most other manufacturers.

8 Group Muting In order to avoid acoustical feedback it may be desirable in certain circumstances to mute speakers associated with adjoining stations when making a paging call. This can be accomplished by interconnecting the Group Mute terminals of each station in the group, and setting the speaker mute jumpers on the circuit boards to the appropriate position. Note: Putting the mute jumper of a station in the on position will mute the associated speaker when the page button is pressed. If the jumper is in the off position the speaker will not be muted when the page button is pressed. If group muting is used the associated speaker of any station in the group with its mute jumper in the on position will be muted when a paging call is made from any station in the group, including the associated station. Any speaker associated with a station with its mute jumper in the off position will not be muted when a paging call is made from any station in the group, including the associated station. If it is desired to bypass a station in a group, connect the group paging wires to the PARK terminals of that station. See: Figure 5 - Electrical Connections Note: Paging calls originating from stations outside the group will be heard regardless of the position of the Mute jumper. EXAMPLE OF GROUP MUTING STATION "A" STATION "B" STATION "C" MUTE JUMPER ON OFF MUTE PARK GROUP MUTE SIGNAL CONDUCTORS If the Group Mute Signal Conductors are attached to the Park terminals of station B that station will be bypassed and paging from stations A or C will have no effect on the output of the loudspeaker associated with Station B. If the Group Mute Signal Conductors are attached to the Mute terminals of station B the condition of the loudspeaker associated with that station will depend on the setting of the Mute On/Off jumper. If the jumper is in the ON position the loudspeaker will be muted if a paging call is made from any of the three stations. If the jumper is in the OFF position the paging call will not be muted if a paging call is made from any of the three stations. Paging calls from outside the Group will always be heard, regardless of the position of the mute jumper. Page 8
9 Ambient Noise Level Adjustment The Ambient Noise Sensor on Guardian's Page/Talk stations automatically adjusts the volume of the associated loudspeaker up to 10db, so that pages can be heard over the background noise. There are two controls on the circuit board to adjust the Ambient Noise Sensor mechanism. The Paging Speaker Volume Control which is accessible either from the faceplate or from the back of the module sets the volume of the speaker to a comfortable level when the ambient noise is at a minimum. The Ambient Noise Monitor Adjustment Control determines how the speaker volume tracks the ambient noise. That is if the speaker is not loud enough with a high ambient noise the control can be adjusted to increase the volume. Alternatively if the speaker is too loud with a high ambient noise the control can be adjusted to decrease the volume. It is usually not necessary to change the setting of the Ambient Noise Monitor Adjustment Control since it is set at the factory for average conditions. Adjustment could be necessary if for some reason the Ambient Noise Sensor Microphone is shielded from the source of ambient noise or some similar situation exists. Initiating a Call Remove the handset. Ensure that the line is free. Broadcasting a Page Operating the SIP-1 Single Line Station Press and hold the Page button on the handset. Broadcast the page. (e.g. "Joe, I need to talk to you, pick up a handset.") Connecting with a Second Party When the second party picks up their handset, both parties are connected and can carry on a conversation. Freeing the Line Place the handset back on the cradle. Initiating a Call Remove the handset. Operating the SIP-5 Multi Line Station Select a free line using the Line selector. Broadcasting a Page Press and hold the Page button on the handset. Broadcast the page that includes the number of the line you are using. (e.g. "Joe, talk to me on line one.") Connecting with a Second Party When the second party selects the appropriate channel and picks up their handset, both parties are connected and can carry on a conversation. Freeing the Line Place the handset back on the cradle. See: Figure 6 - Circuit Board Layout Note: There is one talk line on the SIP-H-1. Note: Continue holding down the Page button while broadcasting the page. Note: The second party can be located at any other station. Note: There are five talk lines on the SIP-H-5. Note: Continue holding down the Page button while broadcasting the page. Note: The second party can be located at any other station. Page 9
10 Troubleshooting Note: If access to the interior of the SIP-H-1/-5 is required refer to the appropriate section. Station Is Dead But Associated Speaker Is Working No repair possible, return station for repair. Station Is Dead And Associated Speaker Is Not Working Ensure power is being supplied to the station. Check the fuse located on the circuit board and replace if necessary. Correct the problem that caused the fuse to fail. Handset Microphone Volume Too Low Adjust TX level control on circuit board. Handset Receiver Volume Too Low Adjust RX level control on circuit board. Feedback Or Distortion Adjust sidetone level control on circuit board. Inspect the line and connections for shorts and grounds. Sidetone Adjust sidetone level control on circuit board. Station Stays On or Off Hook 1. Ensure power is being supplied to the station. 2. Test the proximity switch in the handset receiver cradle by moving a small, permanent magnet over the area while listening on the handset for the line to open and close. 3. If the movement of the magnet switches the on/off hook condition, the magnet in the receiver cartridge of the handset may be weak try another handset. It is not necessary to wire in the new handset to perform this test if the new handset switches the on/off hook condition, replace the existing handset with the new unit. 4. If the movement of the magnet does not appear to switch the on/off hook condition the handset itself may be defective try another handset. 5. If these remedies do not correct the problem return the station for repair. Excessive Noise on Line Verify no other station's handset is off the hook. Crosstalk Inspect wire terminations for crossed wire pairs.
