control module
• Operating temp: -4 to 158°F (-20 to 70°C)
• Size: 1/2” x 2 1/4” x 1/2”
Function/Application
A temperature control module (TCM) reduces the amount of current flow to a
lockset one second after energizing, thereby lowering the tem per a ture of the lockset trim. A
(TCM) also converts AC power to DC power and should be used on all electrified mortise and
cylindrical locksets.
NOTE: The TCM is not used with any IDH-Max function.
TERMINOLOGY

Closed – A state in which a connection exists between the common terminal and another terminal on the switch.
See Open also.
Common terminal – A terminal on a switch whose contact can be connected to one or more terminals on the switch.
Door status – A switch that monitors whether the door is open or closed. This switch is used to detect a forced entry, or a door that is propped
open.
Inductive load – An electrical device such as a motor, relay, or solenoid.
NOTE: this type of load can cause arcing across switch con tacts and may burn the contacts. See Resistive load and Lamp load also.
Latchbolt status – A switch that monitors whether the latch is engaged or retracted. This switch is used to detect a forced entry, or a latch that
has been taped open.
Lamp load – An electrical device that produces light using a tungsten filament, such as an incandescent light bulb.
Note: this type of load can cause surges of current upon contact closure. This may cause the contacts to weld together. See Inductive load and Resistive load also.
Maintained – Remaining in a given state until the switch lever or button is actuated. Actuating the switch lever or button causes the switch to
change to another maintained state.
Momentary – Remaining in a given state only as long as an external force is applied to the switch lever or button.
NC – (Normally Closed) Switch contacts that are closed as long as no external force is applied to the switch lever or button.
NO – (Normally Open) Switch contacts that are open as long as no external force is applied to the switch lever or button.
Open – A state in which no connection exists between the common terminal or any other terminal on the switch.
Pole – The number of independent circuits in a switch. For example, a double-pole, single-throw switch can control two separately powered
motors.
See Throw also.
Resistive load – An electrical device, such as a heater, having none of the char ac ter is tics of an inductive or lamp load. This type of load is the
least severe on the switch because only a small amount of arcing occurs when the switch contacts open and close.
See Inductive load and Lamp load also.
RQE – Request-to-exit. A switch that allows the user to exit without setting off an alarm. Turning the inside knob or lever actuates the switch
and, when wired to an alarm system, sends a signal to disable or sound an alarm, start a timer, etc.
Throw – The number of circuits, or contacts controlled by each pole. For example, a single-pole, double-throw switch can control a motor with
two contacts—a forward contact, and a reverse contact.
See Pole also.
1300 – Integrated BAS1300/LNL1300 reader electronics board or (ISC) Intelligent System Controller is embedded behind the escutcheon
secured and out of site. Functions with Mercury on-line equipment only.
