Frequently Asked Questions
Hager Companies
Q: What is the maximum electrical rating of monitoring switch?

A: 48 volts AC or DC



Q: What type of switch is used?


A: Single pole double throw – SPDT



Q: What is the wire gauge that Hager Companies uses for their electric hinge modifications?

A: 28 gauge, double insulated, U/L listed



Q: Is the monitoring function for Hager’s EMN adjustable?

A: Yes - See catalog page for further information.



Q: What is the maximum electrical rating of the power transfer modification when the current is intermittent duty?

A: 16.0 Amps – See catalog page for further information.



Q: What is the maximum electrical rating of the power transfer modification when the current is continuous duty?

A: 3.5 Amps



Q: What is the maximum number of wires that a Hager power transfer (ETW) may have?

A: 12 each.



Q: If number of wires is not stated on a power (ETW) hinge, how many wires are supplied as standard?

A: 4 each.



Q: Which would be the most likely substitution for an electrically modified?

A: BB1279 ETW-6



Q: When using an electric strike on exterior pair of doors, which of the following electric modification is the most proper choice?


A: BB1191 ETW-4



Q: When using an electric strike on a pair of doors, with an alarm system, which electric modification is required?

A: BB1191 ETM-4



Q: A product (exit device) with 18 gauge wires will work properly with another product (hinge) with 28 gauge wires?

A: True.
(For number of wires for other manufacturer's products, please contact the manufacturer of the product.)



Q: What purpose does a Hager 430 Mortar Guard provide?

A: The 430 Mortar Guard protects the wiring of the hinge from damage that may be caused by grout, debris or drywall in the frame. If the mortar guard is not used, the hinge will not carry its standard warranty.



Q: Is the monitoring function for Hager's EMN is

A: Yes.
(The UL symbol appears next to the drawings of all Hager electrical hinges in the catalog. The symbol indicates all Hager electrical hinges are UL listed.)



Q: Which would be the most likely substitution for an electrically modified BB1279 ETW-4:

A: BB1279 ETW-6
(An electrical hinge may be substituted up, but not down (i.e. A BB1279 ETW-4 could not be substituted for a BB1279 ETW-6). An electrical hinge is normally installed in the center of the door, with the corresponding non-electrical hinges installed on the top and bottom of the door. As the original order is for a standard weight hinge (1279), a heavy weight hinge (BB1199 ETW-8) should not be substituted. The ETW is a power-transfer electrical hinge; a monitoring hinge (BB1279 EMN) should not be substituted. "D" is eliminated, as the hinge material is not specified as either brass or stainless steel. The ETM modification is also almost 2X as expensive as Hager's ETW hinge.)



Q: What type of switch is used for the fully concealed EMN hinge?

A: Single pole double throw - SPDT
(From the descriptive text on p. 9A of the catalog, "The EMN is a monitoring hinge with a concealed subminiature, snap action, SPDT (Single pole double throw) switch.")



Q: What is the wire gauge used by the Hager Companies for their electric hinge modifications:

A: 28 gauge, double insulated, UL listed
(The text, "28 gauge wire is used.” can be found in the description of each Electrical hinge as listed in Hager’s current catalog.)



Q: What is the maximum number of wires for a Hager power transfer (ETW) type hinge?

A: 12 each.



Q: What is the maximum electrical rating of the power transfer modification when the current is intermittent duty – sometimes referred to as “pulse”:

A: 16 Amps.
(Electric Hinges can be located in Hager’s current catalog. In the "Maximum Electrical Rating" table located next to most Electric Hinges, 16.0 amps for Intermittent or Pulse duty are listed.)



Q: What purpose does a Hager 430 Mortar Guard provide?

A: The purpose of a 430 Mortar Guard is to protect the hinge from damage (Serves as a mortar shield).



Q: When using an electric strike on a pair of doors, which Hager electric modification should be used?

A: ETW (Electric Through Wire only)



Q: Can Hager provide electric swing clear applications, raised barrel, jamb surface mount, half surface, half mortise, full surface, wide throws, two-knuckle hinges?

A: Consult with Technical Services Managers for detailed information.



Q: What is the maximum electrical rating of the monitoring switch for Hager's fully concealed EMN hinge:


A: 48 volts AC or DC
(The electrical ratings for the EMN hinge are located in the table appearing in the current version of the Hager catalog.)
