When you see this Signal Word on the following pages, it will alert you to the possibility of damage to your door and/or the door operator if you do not comply with the cautionary statements that accompany it. [. . . ] This proximity switch must be mounted in the same room as the release device. RELAY AND TROUBLE OUTPUTS OPTION Connect wiring from the Alarm Relay Outputs (#11 N/C or #13 N/O and #14 Common) to the appropriate inputs on the fire alarm control panel to provide a signal at the panel when the release device is in an alarm state. Connect wiring from the Trouble Relay Outputs (#14 N/C or #16 N/O and #15 Common) to the appropriate inputs on the fire alarm control panel to provide a signal at the panel that the release device is in a trouble state (Figure 9). If these features are desired, coordinate the interconnection between the Release Device and the Fire Alarm Control Panel with the fire alarm installer. ANNUNCIATOR OPTION To power one or two (maximum) horn/strobes or similar annunciators , connect wiring to terminals 9 and 10 (Figure 10). Route wires through the non-conductive sleeving (provided) covering any exposed bare wires. Maximum distance of wire run within conduit not to exceed 20' total This is a supervised, non power-limited circuit. NOTE: If installing two visual annunciators, they must be installed on opposite sides of wall.

Horn/Strobe 9 Horn/Strobe + + 10k Ohm @ 1/2 watt Supervisory Resistor (LMEOLRES-10) Non-conductive sleeve 10 Terminal Strip ­ ­ Horn/Strobe Annunciator #LMHS2475ADA WIRING OPTIONAL CONNECTIONS (cont'd) VOICE BOARD OPTION The voice board provides one of two verbal warnings that the fire door is closing. Typically, depending on the length of the delay chosen on the release device, a warning tone will occur prior to the message, which is approximately 10 seconds in length (for example, a 20 second delay setting on the release device will result in a 10 second warning tone followed by the verbal warning message). There are two messages that may be selected: Message 1: Warning tone followed by the message, "Warning!An emergency condition exists and this fire door is about to close; please remove any obstructions from its path and stand clear. " Message 2: Warning tone followed by the message, "Warning!the fire door is now closing; please remove any obstructions from its path and stand clear. " The release device has an 4-position DIP Switch mounted on the circuit board, and the switch at position #3 permits selection of either message. In the "ON" position, Message 1 is activated; in the "OFF" position, Message 2 is activated. The voice board can drive up to two 70. 7V speakers (Model LM8SP) or speaker inputs to speaker strobes (Model LMPSTR2475ADA). A potentiometer (VR1) is mounted on the board and rotation counterclockwise increases the volume (clockwise to decrease volume) (Figure 11). DIP SWITCH SELECTION The release device will provide a factory default delay of 10 seconds (to minimize nuisance alarms) before releasing the fusible link chain upon alarm or power loss. A 4-position DIP Switch found on the PC board within the release device can be used to adjust the length of the delay to one of four preset delays. The optional delay settings are as follows: Delay Setting 1 10 Seconds 20 Seconds 30 Seconds 60 Seconds Off Off On On Switch Position 2 Off On Off On 3 Off Off Off Off 4 Off Off Off Off FIGURE 11 Volume Control CCW for Max Wire to Speaker FIGURE 12 NOTE: Position 4 is unused and should remain in the OFF position. Position 3 is used to select one of the two available voice messages. ON 1 2 3 4 Factory default setting of 10 seconds shown. NOTE: Set all DIP switch options before applying power to the system. 10 TESTING TEST PROCEDURES TO BE PERFORMED BY FACTORY AUTHORIZED PERSONNEL ONLY!CLEAR FIRE DOOR OPENING AND PROHIBIT TRAFFIC THROUGH DOOR OPENING WHILE TESTING!Testing does not affect normal operation of alarm system when connected to release device/control panel. [. . . ] If lit, indicates that the fire door or shutter is closed and activating the proximity switch. If not lit, refer to the Close Door Detection section of this manual for correct wiring instructions. If lit, indicates a trouble condition (a short) within the annunciator loop (emanating from terminal board positions 9 and 10), resulting from either incorrect wiring or incorrect placement of the end-of-line resistor. Refer to the Annunciator section of this manual for correct wiring instructions. [. . . ]
